They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering.

As shown in Figure 1, to raise the converter output voltage a resistor must be placed between the Trim pin and Return pin. The WPA60C is equipped with a primary ON/OFF pin used to remotely turn the converter on or off via a system signal. The input is TTL open-collector and/or FET open-drain compatible. For the positive logic model a system logic low signal will turn the unit off. For negative logic models a system logic high signal will turn the converter off. For negative logic models where no control signal will be used the ON/OFF pin should be connected directly to –Vin to ensure proper operation. For positive logic models where no control signal will be used the ON/OFF pin should be left open for normal operation. + Vout1 + Vin RL1 Trim ON/OFF WPA60C (Top View) RT Return RL2 + Vout2 - Vin + Vout1 + Vin Trim Figure 1 – Trim Up Circuit ON/OFF To lower the converter output voltage a resistor must be placed between the Trim pin and Vout1 pin as shown in Figure 2.

If trimming is not desired then the Trim pin should be left unconnected. Product: www.cd4power.com WPA60R48DC The over temperature shutdown feature of the WPA60C will cause the unit to shutdown at a typical pwb temperature of 120oC. This protective feature is comprised of a thermistor in the unit control loop. At a temperature of 120oC this circuit will cause the PWM to go into an idle mode, resulting in no output from the converter and preventing damage to the converter components. When the temperature of the unit drops below 120oC the fault condition will clear and the converter will resume normal operation. If the cause of the over temperature condition is not identified and corrected the unit will continue to cycle on and off. REV A: RoHS 08/2006 4 APPLICATION NOTES Input Under-Voltage Shutdown Performance Characterization The nominal input voltage for the WPA60C is 48Vdc. At an input voltage of 32.5Vdc nominal the unit will shutdown on an input under-voltage condition. At an input voltage less than 32.5V the under-voltage sensing circuit will send a signal to the PWM causing it to go into idle mode. This will result in no output from the converter, protecting the unit from a high input current condition. When the input voltage returns to a level above 32.5V the unit will return to normal operation. The unit will typically turn on at an input voltage of 34.5V nominal as indicated on the Product Data Sheet. This is due to hysterisis designed into the protective circuit to prevent excessive cycling of the converter. Thermal Derating Over-Current Protection Efficiency To protect against fault or short-circuit conditions on the output, each module is equipped with current-limiting circuitry designed to provide continuous protection. After reaching the current limit point (typically 20% above the rated output current), the voltage will range between its rated value and zero, depending upon the amount of overload. The unit will remain in operation continuously during this period down to a short-circuit condition. Once the short or overload has been eliminated, the output voltage will return to normal without cycling the input power. Efficiency data for each model was determined as a function of Load Current and Input Voltage. Efficiency vs. Load Current was measured at an ambient temperature of 25oC, an airflow of 300LFM with an input voltage of 48Vdc. Efficiency vs. Input Voltage was measured at an ambient temperature of 25oC, an airflow of 300LFM and rated load. Graphs for each model are provided in their respective section. Safety The WPA60C meets safety requirements per UL/ CUL 60950 and VDE to EN60950. Additionally, the converter meets CISPR22/ EN55022/ FCC15J Class B specs for EMI levels with external filtering. Product: www.cd4power.com WPA60R48DC Maximum ouput current vs. ambient temperature at various airflow rates has been determined for each model of the WPA60C. From these graphs, the combination of maximum ambient temperature and minimum airflow for select output current combinations can be determined. Each model was analyzed for maximum allowable output power over an ambient temperature range of 0 to 85oC and for airflows up to 600LFM. In each case the maximum allowable power at a given airflow and ambient temperature is defined as the point at which a known component reaches its individual temperature limit. Start-Up, ON/OFF and Transient Response For each model, waveforms are provided showing output voltage response and timing to input voltage power up/down, Remote ON/OFF state change and load current transient responses. Separate traces are provided showing the on/off timing sequence of the two outputs relative to one another. Output voltage transient responses are provided for step load changes of 50% - 100% of rated load current and 100% - 50% of rated load. Waveforms for each model are provided in their respective section.
