These extremely compact DC-DC converters incorporate all necessary input and output filters, signaling and protection features, which are required in the majority of applications. The converters provide important advantages such as flexible output power through primary current limitation, high efficiency, excellent reliability, very low ripple and RFI noise levels, full input to output isolation, negligible inrush current, overtemperature protection, and input over-/undervoltage lockout. The converter inputs are protected against surges and transients occurring on the source lines. Full system flexibility and n+1 redundant operating mode are possible due to virtually unrestricted series or parallel connection capabilities of all outputs. In parallel connection of several converters, automatic current sharing is provided by a single-wire interconnection. The converters are particularly suitable for rugged environments, such as railway applications. They have been designed in accordance with the European railway standards EN 50155 and EN 50121-3-2. All printed circuit boards are coated with a protective lacquer. The outputs are continuously open- and short-circuit proof.

The switching frequency is approximately 200 kHz under nominal operating conditions. The built-in high-efficient input filter together with a small input capacitance generate very low inrush currents of short duration. After transformer isolation and rectification, the output filter reduces ripple and noise to a minimum without compromising the dynamic ability. The output voltage is fed to the secondary control circuit via separate sense lines. The resultant error signal is sent to the primary control circuit via a signal transformer. Double-output models have the voltage regulation of output 2 relying on the close magnetic coupling of the transformer and the output inductor together with the circuits' symmetry. The current limitation is located at the primary side, thus limiting the total output current in overload conditions. This allows flexible loading of each output for unsymmetrical loads in the range 10 to 90% of the total output power. In applications with large dynamic load changes, we recommend connecting such a load to output 1. If output 2 is not used, it should be connected parallel to output 1. Both outputs can either be series- or parallel-connected (see Electrical Output Data). In normal operation, the internal control circuits are powered by a third winding of the main choke (except 48 Q models). Start-up is ensured from the input voltage by a linear regulator. Note: When the output voltage is much lower then the nominal value, this linear regulator is activated, generating considerable power losses. 03111a 2 22 Out OK+ Primary control circuit i 28 Output monitor 24 Out OK- Output control 18 T 16 R3 12 S+1 Vi+ 30 Input filter Output filter 4 Vo+ 6 Vo+ 8 Vo- 10 Vo- Vi- 32 Fuse Cy 1 26 Cy 14 S-1 Isolation 20 1 2 Leading pins Potentiometer for option P Fig. 6 Block diagram of a single-output converter 3 4 4 Do not connect for models xQ1101 or with option P Do not connect 03112a 2 22 Out OK+ Primary control circuit i 28 Output monitor Vo2 24 Out OK- Output control 18 T 16 6 R3 Vo2+ Output filter Vi+ 30 10 Vo2- Input filter 12 S+1 Vi- 32 Fuse Cy 1 26 20 Leading pins 2 Potentiometer for option P Fig. 7 Block diagram of a double-output converter BCD20011- G Rev AG, 12-Mar-2012 Vo1+ 8 Vo1- 14 Cy Isolation 1 4 Output filter 3 Do not connect for models with option P Page 5 of 26 4 S-1 4 Do not connect www.power-one.com Q Series Data Sheet 66 - 132 Watt DC-DC Converters (R) Electrical Input Data General Conditions: - TA = 25 C, unless TC is specified. - Sense lines connected directly at the connector, inhibit (28) connected to Vi - (32). - R input not connected; with option P, Vo set to Vo nom at Vi nom.

The fuse is not externally accessible. Reverse polarity at the input will cause the fuse to blow. If a Q Series converter is connected to the power source with long input lines which exhibit a considerable inductance, an additional external capacitor connected in parallel to the input improves stability and avoids oscillations. Note: Customer-specific models with no internal fuse are available on request; the customer must prevew an external fuse according to table 3. Actually, a Q Series converter with nominal load acts like a negative resistor, as the input current rises when the input voltage decreases. It tends to oscillate with a resonant frequency determined by the line inductance Lex t and the input capacitance Ci + Cext and damped by the resistors Ri + Rext. The whole system is not linear at all and eludes a simple calculation. One basic condition is given by the formula: Vin --* Rext << ---- Po Rext is the series resistor of the source voltage including input lines. If this condition is not fulfilled, the converter cannot reach stable operating conditions. Worst case conditions are low input voltage Vi and high output power Po.

Nominal battery voltages in use are: 24, 36, 48, 60, 72, 96, and 110 V. In most cases each nominal value is specified in a tolerance band of -30% to +25%, with short excursions to 40% or even more. In some applications, surges according to RIA 12 are specified in addition to those defined in IEC 60571-1 or EN 50155. The power supply must not switch off during these surges and since their energy can practically not be absorbed, an extremely wide input voltage range is required. The Q Series input range has been designed and tested to meet most of these requirements. See also Electromagnetic Immunity.

Inrush Current The inherent inrush current value is lower than specified in the standard ETS 300132-2. The converters operate with relatively small input capacitance, resulting in low inrush current of short duration. As a result, in a power-bus system the converters can be hot-swapped, causing negligible disturbance. BCD20011- G Rev AG, 12-Mar-2012 Low inductance Lext of the input lines and a parallel connected input capacitor Cext are helpful.

There is no inconvenience or restriction using the Rinput with sense lines. Single-output and/or double-output models can be connected in series.

The current sharing may be improved by interconnecting the T pins of the converters. This circuit is a bit less accurate, but more flexible and less sensitive. T Out OK+ If one of the converters fails, the remaining converters can deliver the whole output power. Fig. 10b shows a quite similar circuit with ORing diodes DR, but with different output loads. To compensate for the voltage drop of the ORing diodes (if necessary), an auxiliary circuit is added to each power supply consisting of a small diode DS and a small resistor RS. We recommend a current of approximately 10 mA through DS and RS. Only Load 0 benefits from a secured supply voltage. Vo+/Vo1+ Out OK+ produce reasonable current sharing between the parallelconnected converters. Caution: Do not connect the sense lines after the ORing diodes, but directly with the respective outputs. If for some reason one of the converters switches off and the ORing diode is blocking, a reverse voltage can appear between the sense pin and the respective output pin and damage the converter.

Correct connection of the sense lines almost eliminates any load regulation; see Sense Lines. T Out OK+ 10 s 0 Load 1 Out OK+ In a symmetrical configuration the output 1 with open R input is regulated to Vo1 nom, regardless of the output currents. If the load on output 2 is too small (<10% of Io nom), its voltage will rise and may activate the overvoltage protection, which will then reduce the voltage on both outputs. Vo2 depends upon the load distribution: If each output is loaded with at least 10% of Io nom, the deviation of Vo2 remains within 5% of Vo nom. The following figures explain the regulation with different load distributions up to the current limit. If Io1 = Io2 or the two outputs are connected in series, the deviation of Vo2 remains within 1% of the value of Vo nom, provided that the load is at least Io min. Page 13 of 26 www.power-one.com Q Series Data Sheet 66 - 132 Watt DC-DC Converters (R) Note: If output 2 is not used, we recommend to connect it in parallel to Vo1. This results in improved efficiency and stability. Vo2 [V] Vo2 max = 14.2 V 05111a There is no specific built-in protection against externally applied overvoltage. Io1 = 7.2 A Io1 = 5.6 A Io1 = 4.0 A Io1 = 2.4 A Io1 = 0.8 A Vo1 + 0.5 V (in double-output models, the 2 nd output is monitored). This circuitry further protects the load in the unlikely event of a malfunction of the main control circuit. Note: If output 2 is not loaded, the 2nd control loop may reduce V01 under boundary conditions. Output Current Protection Vo1 All outputs are fully protected against continuous open-circuit condition or continuous short-circuit by an electronic current limitation located on the primary side.

However, a small current should remain on both outputs to guarantee good voltage regulation. In case of overload (Io1 + Io2 > Io max) both output voltages are reduced simultaneously. 05112a Io1 = 6.0 A Io1 = 4.6 A Io1 = 3.3 A Io1 = 2.0 A Io1 = 0.66 A Vo1 + 0.5 V Single-output models and series- or parallel-connected double-output models have a quasi rectangular constant current limitation characteristic. Current distribution in overload is dependent upon the type of overload. A short-circuit in one output will cause the full current flow into that output, whereas a resistive overload results in more even distribution and in a reduced output voltage.

A nonconnected pin 28 will be interpreted by the internal logic as an active inhibit signal and the output(s) will remain disabled (fail safe function). An inhibit input enables (logic low, pull down) or disables (logic high, pull up) the output, if a logic signal, e.g. TTL, CMOS is applied. In systems consisting of several converters, this feature may be used, for example, to control the activation sequence of the converters by means of logic signals, or to allow the power source for a proper start-up, before full load is applied.

This feature avoids that some converters are driven into current limitation and thus produce excessive losses. As a result, the stress of the converters is reduced, and the system reliability is further improved. Simple interconnection of the T pins causes the converters to share the output current. The current tolerance of each converter is approx. 20% of the sum of its nominal output currents Io1 nom + Io2 nom. In n+1 redundant systems, a failure of a single converter will not lead to a system failure, if the outputs are decoupled by diodes; see fig. 10. BCD20011- G Rev AG, 12-Mar-2012 Note: T-function only increases the output voltage, until the currents are evenly shared. If in a redundant system, one converter fails, the remaining converters keep sharing their currents evenly. Since the T pins are referenced to the pins S -, the S- pins of all converters must have the same electrical potential. Double-output converters with both outputs connected in series can also be paralleled with current sharing, if pins Vo1- of all converters are connected together, see fig. 8c. If the output voltages are programmed to a voltage other than Vo nom by means of the R pin or option P, the outputs should be adjusted individually within a tolerance of 1%. Important: For applications using the hot-swap capabilities, dynamic output voltage changes during plug-in/plug-out must be considered. Page 16 of 26 www.power-one.com Q Series Data Sheet 66 - 132 Watt DC-DC Converters (R) Programmable Output Voltage (R-Function) Note: R-inputs of n converters with paralleled outputs may be paralleled too, but if only one external resistor is used, its value should be R1/n or R2/n, respectively. This feature is not available on models with 3.3 V output or with option P. 06093b Note: Models with 3.3 V output or with option P: The R-input must be left open-circuit. Doubleoutput model The converters offer a programmable output voltage. The adjust is performed either by an external control voltage Vext or an external resistor R1 or R2, connected to the R-input.

It can be used for control functions such as data protection, central system monitoring or as a part of a self-testing system. It can be connected to get a centralized fault detection or may be used for other systemspecific applications at the primary or the secondary side of the converter. Connecting the Out-OK as per fig. 22, VOK <1.0 V indicates that the Vo or Vo1 of the converter is within the range V t1 low - Vt1 high. V t1 low corresponds to 0.95 - 0.98 Vo1 nom, V t1 high to 1.02 - 1.05 Vo1 nom. Note: Using the R-input or the option P, the monitor level is tracking the programmed output voltage. In an error condition, if the output voltage is out of range due to overload or an external overvoltage, VOK will approach Vp. The output is formed by an NPN transistor. The emitter (Out OK-) can be connected to primary Vi- or secondary Vo1- to get an open-collector output. In a configuration of several Q Series converters, the Out OK pins can be series-connected in order to get a system level signal (as shown in fig. 9). If one of the converters fails, the series-connected output rises to high impedance.

The test sockets are protected by internal series resistors. Double-output models show the sense line voltage of output 1 at the test jacks. 48Q models have no test jacks. Fig. 22 Out OK function Vp Dimensioning of resistor value Rp ------ 0.5 mA Caution: Out-OK is protected by an internal series resistor and a Zener diode. To prevent damage, the applied current IOK should be limited to 10 mA. 48Q models exhibit a green LED In-OK to monitor the input voltage. BQ - GQ models have an additional LED Out-OK, which is activated simultaneously to the Out-OK signal. Table 12: Display status of LEDs Table 10: Out-OK data Conditions VOK Out-OK voltage Output okay, IOK < 0.5 mA IOK Caution: Sense lines should always be connected. Incorrectly connected sense lines may cause an overvoltage at the ouput, which could damage the output load and activate the second control loop. The sense lines can handle only small currents. Note: Sense line connection in a redundant configuration is shown in fig. 10. Out OK+ 22 24 Characteristics To ensure correct operation, both sense lines must be connected to their respective power output. With doubleoutput models, the sense lines must be connected to output 1 only. Caution should be exercised, if outputs are seriesconnected, as the compensated voltage is effectively doubled. Because the effective output voltage and output power are increased by the sense lines, the minimum input voltage rises proportionally to the compensated output voltage. + Vp 06096a Output control circuit Applying generously dimensioned cross-section load leads help avoiding troublesome voltage drops. To minimize noise pick-up, wire the sense lines parallel or twisted. For unsymmetrical loads, we recommend connecting the sense lines directly at the female connector.

See Input Stability with Long Supply Lines. Due to high output currents, the Q1001/1101 models offer two internally parallel-connected contacts for both, the positive and the negative output path (pins 4/6 and pins 8/10). It is recommended to connect the load to both female connector pins of each path in order to keep the voltage drop across the connector pins to a minimum. Make sure that there is sufficient air flow available for convection cooling. This should be verified by measuring the case temperature when the converter is installed and operated in the end user application. The maximum specified case temperature TC max shall not be exceeded. See also Thermal Considerations. Ensure that a converter failure (e.g. by an internal short-circuit) does not result in a hazardous condition. See also Safety of Operator-Accessible Output Circuits. Cleaning Agents In order to avoid possible damage, any penetration of cleaning fluids must be prevented, since the power supplies are not hermetically sealed. Do not connect pin 16 for models with 3.3 V output or opt. P ! Leading pin (pre-connecting). If not actively used, connect with pin 32. 30 Important: * Do not open the converters, or warranty will be invalidated. Pin 2 The Vi- input (pin 32) is internally fused. This fuse is designed to protect in case of overcurrent and may not be able to satisfy all customer requirements. External fuses in the wiring to one or both input pins (no. 30 and/or no. 32) may therefore be necessary to ensure compliance with local requirements.

The converters comply with class S1 of the fire protection standard E DIN 5510-2 (Oct. 2007). Isolation and Protective Earth The test of the resistance of the protective earthing circuit (max. 0.1 ) and the electric strength test (table 19) are performed in the factory as routine tests in accordance with EN 50116 and IEC/EN 60950-1, and should not be repeated in the field. Power-One will not honor any warranty claims resulting from electric strength field tests. Safety of Operator-Accessible Output Circuits If the output circuit of a DC-DC converter is operatoraccessible, it shall be an SELV circuit according to IEC 60950. Table 21 shows some possible installation configurations, compliance with which causes the output circuit of the DC-DC converter to be SELV up to a configured output voltage (sum of nominal voltages, if in series configuration) of 35 V. However, it is the sole responsibility of the installer to ensure the compliance with the relevant and applicable safety regulations. reduced accordingly, so that the maximum specified output power is not exceeded. Description of Options Option P: Output Voltage Adjustment Option P provides a built-in multi-turn potentiometer, which allows an output voltage adjustment of 10% of Vo nom. The potentiometer is accessible through a hole in the front cover. With double-output models, both outputs are affected by the potentiometer. If converters are parallel-connected, their individual output voltage should be set within a tolerance of 1%. Option -7: Temperature Range Option -7 designates converters with an operational ambient temperature range of - 25 to 71 C. Not for new designs. Option B, B1: Additional Heat Sink Thickness: 12.5 mm (opt. B) or 20 mm (opt.
