The converters have been designed according to the latest industry requirements and standards. The converters 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 12, 24, 36, or 48 V. Special models for battery charging are available. The EW models are particularly suitable for 110 V railway applications; they have been designed in accordance with the railway standards EN 50155 and EN 50121. 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 Table of Contents 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 outputs deliver an electrically-isolated Safety Extra Low Voltage, SELV, (except models LWR/LWN1740) 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). 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.

Functional Description The W Series converters are primary controlled AC-DC or DCDC flyback converters with a constant switching frequency of 130 kHz. The power-factor-corrected single-step conversion of the input voltage to a low output voltage results in extremely high efficiency. Depending upon the output power, the converters are fitted with one (125 W) or two (250 W) powertrains. Models with two powertrains have one or two outputs. Double-output models exhibit indiviually regulated powertrains. The input voltage is fed via fuse, filter, and rectifier to the main transformer, 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. Specific type designation, input voltage range, nominal output voltages and currents, degree of protection, batch no., serial no., and data code including production site, version, and date of production. The secondary side of the 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 each. 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). 03103a Cy 2nd fuse (option F) 1 Rectifier Input filter N 2 Vo- 2 Vo+ + Shunt Shunt Output filter 3 Vo+ Input filter L Fuse 3 6 CY 4 Vo- Cy Cy 7 5 8 Control circuit including PFC and input OVP/UVP Vo/Io control CY 9 1 2nd control loop (SELV) 11 10 AUX Fig. 1 LWR 125 W and LWN 250 W single-output converters.

BCD20020-G REV AA Page 6 of 28 www.power-one.com W Series Data Sheet 125, 250 Watt AC-DC and DC-DC DIN-Rail Converters (R) Output Power Derating The output power of LW models must be decreased at low input voltage and/or powertrain temperature above 125 C. 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 approaching maximum ambient conditions. As a result, the output power has to be reduced according to the tables below. Note: The measurements have been made by the approval boards 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). For models not specified, please contact Power-One. EW models have no derating.

EW models have a smaller fuse (250 V, 4 x 9 mm, SOC NT3 6.3A V009, ULrecognized E-39265). For DC input voltages above 250 V observe the Installation Instructions. 04071 90 Converters with option F have 2 small fuses, one in each input line. Converters with option E and F have 2 large fuses ( T 6.3 A, 5 x 20 mm). The DC input voltage for all converters with option F is limited to 250 V. 80 70 60 A VDR and a symmetrical input filter form an effective protection against input transients. 50 40 An under- and overvoltage lockout protects the converter, which is disabled below Vi min and above Vi max by an internally generated inhibit signal. 30 20 10 The built-in bridge rectifier provides reverse polarity protection at the input if operated from DC. EW models are protected by the (blowing) input fuse in connection with the body diode of the main transistor. Option Q offers a serial diode, but this affects efficiency by approx. 1%.

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.

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.

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 48V outputs), but this creates considerable power losses. Input Thermal Considerations Power supply 03099c Vo+ Vo- Load R 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. + - Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in the table Temperature specifications. 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.

The converters have been designed in accordance with said standards for: * Class I equipment Fig. 19 Cage clamp terminals. Use 0.5 to 2.5 mm2 (AWG 20 to 12) solid or stranded wires depending on local requirements. * Power-supply for building-in, vertical mounting on 35 mm DIN-rail or on a wall * Overvoltage category II (III for 110 VAC supply) * Basic insulation between input and case, based on 250 VAC This fuse is designed to break an overcurrent in case of a malfunction of the converter and is not customer-accessible. * Double or reinforced insulation between input and output, based on 250 VAC and 350 VDC. 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. * Functional insulation between outputs and case. A second fuse in the wiring to the neutral terminal N or option F is needed if: * Local requirements demand an individual fuse in each source line * Neutral and earth impedance is high or undefined * Functional insulation between outputs. * Pollution degree 3 environment (AC-input) and degree 2 (DC input). CB Scheme is available (SE-34392). The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and with ISO9001:2000. * Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals (L to phase and N to neutral). For details see the Declaration of Conformity (last pages). Models with Option F: Caution! Double-pole/neutral fusing. All W Series converters have been designed observing the railway standards EN 50155 and EN 50121. All boards are coated with a protective lacquer. If the converters operate at source voltages above 250 VDC, an external fuse or a circuit breaker at system level should be installed. Caution: Railway Applications The EW Series is particularily suitable for connection to 110 V railway batteries. * Installation must strictly follow the national safety regulations. * Do not open this apparatus! Protection Degree The protection degree of the converters is IP 20. Protective covers over input and output terminals are available on request; see Accessories. Cleaning Agents Any penetration of liquid or foreign solid objects is to be prevented, since the converters are not hermetically sealed.

Power-One will not honor any warranty claims resulting from electric strength field tests. Leakage Currents in AC-DC Operation Leakage currents flow due to internal leakage capacitance and RFI suppression Y-capacitors. The current values are proportional to the mains voltage and nearly proportional to the mains frequency. They are specified at maximum operating input voltage where phase, neutral, and protective earth are correctly connected as required for class I equipment. Leakage current may exceed 3.5 mA, if fi > 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 IEC/EN 60950 related safety standards. 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. It is the sole responsibility of the installer to ensure the compliance with the relevant and applicable safety regulations. 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.

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. If the output voltage drops below Vo low D1, the D1 signal (open-collector) goes to high impedance. I D max <50 mA. The D1 output is protected by a Zener diode against transients up to 75 V (for models with Vo max >50 V up to 90 V). In double-output models D1 monitors only output 2. Reduces the output power to approx.1 W, i.e., the converter is not fully disabled. In a no-load condition Vo drops below 6.2 V; see fig. 23. In double-output models, only output 2 is influenced. 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% Vo nom should be chosen (e.g., for bus voltage 24.7 V, trigger level at 21 V).

The definition of D5 is similar to D1, but the trigger level is lower. When Vo drops below the value specified in the table below, the D5 signal (opencollector) goes to high impedance. I D max < 50 mA. The D5 output is protected by a Zener diode against transients up to 75 V (for models with Vo max >50 V up to 90 V). 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. The D5 signal can be used for instance to disable loads, save data, or to start a controlled switch-off of running processes. Adjustment of Threshold Levels (D1/D5) 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. 22).
