5 wpa60 rev d th/smt 2/2004 product: www.cdpoweronline.com application notes output voltage trim each of the wpa60?s output voltages may be simulta- neously adjusted above or below the nominal set point by a value as indicated on the product data sheet. as shown in figure 1 , to raise the converter output voltage a resistor must be placed between the trim pin and return pin. figure 1 ? trim up circuit wpa60 trim return + vout1 + vout2 + vin on/off - vin (top view) r t r l1 r l2 to lower the converter output voltage a resistor must be placed between the trim pin and vout1 pin as shown in figure 2 . figure 2 ? trim down circuit wpa60 trim return + vout1 + vout2 + vin on/off - vin (top view) r t r l1 r l2 the resistance value required to achieve the desired amount of positive/negative trim can be determined by referring to the trim graph for each model. if trimming is not desired then the trim pin should be left uncon- nected. remote on/off function wpa60 trim return + vout1 + vout2 + vin on/off - vin (top view) control signal the wpa60 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. figure 3 ? remote on/off control circuit protective functions operation temperature shutdown the over temperature shutdown feature of the wpa60 will cause the unit to shutdown at a typical pwb temperature of 120 o c. this protective feature is comprised of a thermistor in the unit control loop. at a temperature of 120 o c 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 120 o c 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.
6 wpa60 rev d th/smt 0 2/2004 product: www.cdpoweronline.com application notes input under-voltage shutdown the nominal input voltage for the wpa60 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. output short circuit protection when a short circuit condition appears on the output the converter will go into hiccup mode. in hiccup mode the converter will cycle on and off repeate dly until the short circuit condition is cleared. safety the wpa60 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 ?ltering. performance characterization thermal derating maximum ouput current vs. ambient temperature at various air?ow rates has been determined for each model of the wpa60. from these graphs, the combination of maximum ambient temperature and minimum air?ow 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 85 o c and for air?ows up to 600lfm. in each case the maximum allowable power at a given air?ow and ambient temperature is de?ned as the point at which a known component reaches its individual temperature limit. ef?ciency ef?ciency data for each model was determined as a function of load current and input voltage. ef?ciency vs. load current was measured at an ambient temperature of 25 o c, an air?ow of 300lfm with an input voltage of 48vdc. ef?ciency vs. input voltage was measured at an ambient temperature of 25 o c, an air?ow of 300lfm and rated load. graphs for each model are provided in their respective section. s tart-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.
