The converters have been designed according to the latest industry requirements and standards. They are ideal for use in outdoor and other demanding applications to power building control systems, factory automation, industrial controls, instrumentation, electromagnetic drives, fans, and other DC loads. Different models are available with a single output or two independently regulated, electrically isolated outputs with 24, 36, or 48 V. Special models for battery charging are available. The outputs deliver an electrically-isolated Safety Extra Low Voltage, SELV, (except models LXR/LXN1740) and low output noise. They are no-load, overload, and short-circuit proof. The electronically controlled short-term peak power capability of up to 150% of the rated output power enables the front end converters to deliver additional power to start-up motors or to safely operate subsequent circuit breakers. Built-in large sized output capacitors absorb possible reverse energy, which may be caused by quick deceleration of electromagnetic drives connected directly to the output. A green LED at the front cover displays the status of the output(s). Key features of the Convert Select line include power factor correction with low harmonic distortion, negligibly low inrush current, high immunity to transients and surges, and low electromagnetic emissions. Internal protection circuits such as input over- and undervoltage lockout, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system. The Convert Select Series was designed according to all relevant international safety standards. The converters are approved by TUV and UL, and are UL 508 listed. Adequate clearances and creepage distances allow operation in pollution degree 3 environment (with AC input). All board assemblies are coated with a protective lacquer.

The power-factor-corrected single-step conversion of the input voltage to a low output voltage results in extremely high efficiency. Depending on the output power, the converters are fitted with three (375 W) or four (500 W) powertrains. 03105 Fuse N Rectifier CY Shunt Shunt 2 2 Vo+ 3 6 7 CY Cy Cy 2nd fuse (option F) Output filter Cy Input filter 3 Input filter L 4 Vo- 5 8 9 1 Control circuit including PFC and input OVP/UVP Vo/Io control 1 12 2nd control loop (SELV) 10 Aux1 11 Aux2 Fig. 1 LXR 375 W single-output converter. 03106 N 2 2nd fuse (option F) + Shunt Shunt Output filter Rectifier Cy Cy Cy 1 Input filter Control circuit including PFC and input OVP/UVP 2 Cy 4 Cy 6 Cy 8 3 5 Vo+ Vo- 2nd control loop (SELV) + Shunt Shunt Cy Control circuit including PFC and input OVP/UVP Cy Vo/Io control Vo/Io control 2nd control loop (SELV) Output filter 3 Input filter L Input filter Fuse 7 9 Vo+ Vo- 1 12 10 Aux1 11 Aux2 Fig. 2 LXN 500 W double-output converter For the pinout of 500 W single-output models see fig. 1.

Double-output models exhibit individual control of each output. The input voltage is fed via fuse, filter, and rectifier to the powertrains with main transformers designed in planar technique. The input filter with very small input capacitance generates virtually no inrush current. An input transient suppressor protects the converter against high voltage peaks and surges. Input over- and undervoltage lockout as well as input current limitation protect the converter from operation outside of its specification. The input voltage waveform is sensed by the primary control logic to allow active power factor correction, forcing the input current to follow the input voltage waveform. The secondary side of each main transformer supplies via the rectifier diode a large electrolytic output storage capacitor providing for the hold-up time. Double-output models exhibit an individual control logic for each output. The output voltage and the output current are measured and fed back to the primary control logic via an optocoupler. A second control loop monitors the output voltage. It disables the output in the case of a failure in the control logic and limits the output voltage. Built-in temperature sensors monitor the internal temperature of each powertrain. If the temperature exceeds the limit, the converter reduces the output power continuously to keep the temperature below its limit. A green LED on the front cover confirms the presence of the output voltage(s). The R input (option R, M1, or M2) allows for external adjustment of the output voltage by means of a resistor or an external voltage source. An external sensor can be connected to the R input and allows for temperature-controlled battery charging; see Accessories.

The powertrain temperature depends on the output power, the input voltage, and the cooling method. At low input voltage the losses increase. At the maximum specified environment temperature TA free air convection cooling might be insufficient. As a result, the output power has to be reduced according to the tables 4 and 5. An under- and overvoltage lockout protects the converter by disabling it below Vi min and above Vi max. The built-in bridge rectifier provides reverse polarity protection at the input if operated from DC. Efficiency [%] Note: The measurements have been made at the approval tests with free air convection cooling according to UL 60950, specified ambient temperature TA, and with the converter built in a cardboard box according to UL 508 and a specified temperature outside the box Tout. The tables give a correlation between TA or Tout and the case temperature TC (measuring point TC see Mechanical Data).

Both outputs can be connected in parallel, provided that the options S (included in M1) and R are not used, since they influence only the 2nd output. The two pairs of powertrains share the current due to their output voltage droop characteristic. AUX1 10 Vi Vo+ 6 Vo- 5 Up to 3 converters with the same output voltage may be operated in parallel. It is possible to parallel W Series with X Series converters. Reasonable current sharing is achieved by the droop characteristic. Correct mode of operation is highly dependent upon the wiring of the converters and the impedance of these wires. Use wires with equal length and equal cross sections of min. 1.5 mm 2. The best results for parallel operation can be achieved with the wiring shown in fig. 6. Parallel operation of single-output models using option R (output voltage adjust) is possible, but not recommended.

However, it is possible to insert bleeding resistors in the Vo+ output lines of each converter in order to create a droop of approx. 0.6 V @ Io nom for 24 V outputs (1.2 V @ Io nom for 48 V outputs), but this creates considerable power losses. 03099d Thermal Considerations The thermal conditions are influenced by input voltage, output current, airflow, and temperature of surrounding components. TA max is therefore, contrary to TC max, an indicative value only. Input + - Note: Sufficient forced cooling allows TA to be higher than TA max provided that TC max is not exceeded. It is recommended that continuous operation under worst case conditions of the following 3 parameters be avoided: Minimum input voltage, maximum output power, and maximum temperature.

Protective covers over input and output terminals are available on request; see Accessories. 1 3 Any penetration of liquid or foreign solid objects has to be prevented, since the converters are not hermetically sealed. Standards and Approvals 2 The X Series converters were approved according to IEC/ EN 50178, IEC 61010-1, IEC60950-1, UL/CSA 60950-1 2nd Ed. The converters have been designed in accordance with said standards for: Fig. 16 Cage clamp terminals. Use 0.5 to 2.5 mm 2 (AWG 20 to 12) solid or stranded wires depending on local requirements. * Class I equipment * Power-supply for building-in, vertical mounting on 35 mm DIN-rail or on a wall * Overvoltage category II (III for 110 VAC supply) The phase input (L) is internally fused; see Input Fuse and Protection. This fuse is designed to break an overcurrent in case of a malfunction of the converter and is not customeraccessible. External fuses in the wiring to one or both input lines (L and/or N ) may be necessary to ensure compliance with local requirements. A built-in second fuse in the neutral path is available as option F. A second fuse in the wiring to the neutral terminal N or option F is needed if: * Basic insulation between input and case, based on 250 VAC * Double or reinforced insulation between input and output, based on 250 VAC and 350 VDC * Functional insulation between outputs and case * Functional insulation between outputs * Pollution degree 3 environment (AC-input) and degree 2 (DC input). CB Scheme is available (SE-34628). * Local requirements demand an individual fuse in each source line The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and with ISO9001:2000. * Neutral and earth impedance is high or undefined See also the Declaration of Conformity (last page). * Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals (L to phase and N to neutral). Railway Applications Models with option F: Caution! Double-pole/neutral fusing. If the converter operates at source voltages above 250 VDC, an external DC fuse or a circuit breaker at system level should be installed in the phase input line L . Caution: * Installation must strictly follow the national safety regulations. * Do not open this apparatus! All X Series converters have been designed by observing the railway standards EN 50155 and EN 50121. All boards are coated with a protective lacquer. Isolation The electric strength test is performed in the factory as routine test in accordance with EN 50116 and IEC/EN 60950, and should not be repeated in the field. Power-One will not honor any warranty claims resulting from electric strength field tests.

The current values are proportional to the voltage Vi and the frequency fi of the supply (mains). The leakage currents are specified at maximum operating input voltage, provided that phase, neutral, and protective earth are correctly connected as required for class I equipment. Caution: Leakage current may exceed 3.5 mA, if f i > 63 Hz. Safety of Operator-Accessible Output Circuits If the output circuit of a converter is operator-accessible, it shall be a SELV circuit according to the safety standards IEC/EN 60950. Description of Options The converters have SELV output circuits up to an output voltage of 57.5 V. However, if the isolated outputs are connected to another voltage source or connected in series with a total of >57.5 V, the outputs are hazardous. LED Indicator A green LED is activated, when the output voltage Vo is within the normal operating tolerance band. Note: This LED is also activated, when the converter is not powered by the input, but a loaded battery is connected to the output.

In double-output models, D1 monitors only output 2 (Vo2). Description In applications without battery-buffering the D1 signal may not be suitable, since smaller dynamic load changes may cause D1 to trigger. For such applications, D5 with a trigger level of approx. 85% of Vo nom should be chosen (e.g., for a bus voltage of 24.7 V: trigger level at 21 V). Adjustment of trigger values D1 and D5 In double-output models, only output 2 is concerned. D5: System Volt. Monitor (Battery Deep Discharge) Multiple Options M1 or M2 The option board is suitable for applications, where several options are needed. Option M1 is standard for battery charger models, option M2 is suitable for applications without battery or for simple applications with battery. In general, the multiple options M1 or M2 are connected to an additional D-SUB connector. Some signals (but not option R) can also be connected to AUX1 and AUX2, if the D-SUB connector is not suitable to the customer. D2: Input Voltage Monitor (Power Fail) D2 monitors the input voltage V i. When V i drops below 653 VAC or 92 VDC, the D2 signal output is high impedance (open-collector, max. 50 V). D5 monitors the output voltage Vo (Vo2 in double-output models) or the lowest admissible voltage of a connected battery (battery deep discharge). The definition of D5 is similar to D1, but the trigger level is lower. When Vo (or Vo2) is greater than Vo low D5 specified in table 17, the D2 signal output is conducting: VD5 < 1.5 V, I D5 max < 50 mA. When Vo is lower, the D5 signal output is high impedance (open-collector, max. 58.6 V). In double-output models, D5 monitors only output 2 (Vo2). In systems without battery support, D5 signals that Vo (or Vo2 ) is going to drop below a safe value. In battery-buffered systems, D5 indicates that the battery has reached its deepest discharge level prior to getting damaged. When V i is greater then said level, the signal output D2 is conducting: VD2 < 1.5 V, I D2 max < 50 mA. The D5 signal can be used for instance to disable loads, save data, or to start a controlled switch-off of running processes. D1: Output Voltage Monitor Adjustment of Threshold Levels (D 1 or D 5) D1 is intended for monitoring the bus voltage of a batterybuffered system. It indicates that the system is powered from the battery and can for instance be used as warning signal or to switch off a part of the load. When the output voltage Vo (or Vo2) is greater than Vo low D1 specified in table 17, the D1 signal output is conducting: VD1 < 1.5 V, I D1 max < 50 mA. Pin 7 of the D-SUB connector allows for adjustment of the threshold levels of D1 and D5. Both levels are influenced by the voltage divider Rx / Ry. Resistor Rx to pin 3 (VCC) lowers the levels, whereas Ry to pin 1 (GND1) increases them; see fig. 19.

Converter disabled (Po approx. 1 W) Converter enabled Note: If longer wires are used to connect the R input at the D-SUB connector, the wiring to pin 1 (GND1) should be done as a star point connection. If wired differently, the output voltage setting may be adversely affected. Sys-OK: Status This function allows in a battery charger application for checking, whether the output is correctly following the external control signal at the R-input (coming for instance from the temperature sensor). The logic is shown in table 19. The open-collector output Sys-OK is protected by a Zener diode and withstands up to 58.6 V. When the system status is OK, the signal output is low: VSys-OK < 1.5 V, I Sys-OK < 50 mA. R: Adjustment of Vo or Vo2 The R input allows external adjustment of the output voltage in the range of 50% to 110% Vo nom. Double-output models allow only adjustment of output 2 (connected to the terminals 6, 7, 8, and 9). This enables asymmetric output voltage configuration. In battery charging systems, an external battery temperature sensor (see Accessories) can be connected to optimize Vo. However, adjustment using the R input (pin 2 of D-SUB) is possible as well. The above shown formulas are valid, but Vo nom stands for the voltage with open R input (= Vo safe). F: Built-in Second Fuse A built-in second fuse in the neutral line provides safe phaseto-phase connection at low mains voltages (e.g. USA 120 / 208 V /60 Hz systems). The built-in second fuse also enables safe connection to the mains, where phase and neutral are not defined or cannot be identified, as e.g. in the case of plug and socket connection to Table 20: System OK (M1 with external battery sensor) System Status Input Vcontrol sensor signal VBat theoretical VBat measured Sys-OK output System OK O.K. 2.7 V 27 V 27 V Low ohmic Battery overchared / temp. sensor defect / control voltage to high O.K. 2.7 V 27 V 28 V High ohmic Overload, converter cannot follow the control signal O.K. 2.7 V 27 V 24 V High ohmic Output does not follow control signal, since battery would be overcharged O.K. 3.0 V 30 V 27 V High ohmic System OK O.K. 2.5 V 25 V 25V Low ohmic BCD20021-G Rev AC1, 13-May-2013 Page 19 of 21 www.power-one.com X Series Data Sheet 375, 500 Watt AC-DC and DC-DC DIN-Rail Converters (R) the mains via German Schuko-plugs; see also Safety and Installation Instructions.
