(1.000) external output trimming (6) output can be externally trimmed by 10% using either method shown below. notes 1 nominal inputs are 24vdc and 48vdc. 2 maximum figure at full load. 3 measured from high line to low line. 4 measured as load changes from 20% to 100% full load. 5 remote sense will compensate for a load line voltage drop of up to 400mv per leg. if the remote sense facility is not utilised, output sense pins must be jumpered to the respective output power pins. for normal operation connect pin 3 to pin 6 and pin 5 to pin 7. 6 to trim the output voltage, connect a resistor from pin 4 to pin 3 (trim down) or pin 4 to pin 5 (trim up). a trim resistor value of zero ohms yields the maximum output change of approximately 10%. 7 the remote on/off control can be used as undervoltage shutdown signal for the converter. a user-provided input undervoltage circuit can start the converter by toggling the remote on/off control when the input voltage is within proper limits. 8 the wp series includes a special amp-reg circuit that allows paralleling multiple converters, either directly or with isolation diodes. the circuit is essentially an output current limit set at 105% of stated maximum output. when multiple converters are paralleled, the converter with the highest output voltage will provide all the output current until it reaches current limit. then its output voltage begins to drop and the converter with the next highest output voltage starts to contribute current. the wp series are designed to operate reliably in current limit indefinitely. 9 fixed frequency design provides for easier input filtering and better noise performance. 10 in many cases, the isolation specification may be upgraded. consult factory for details. 11 standard specifications are conservative and can be optimised for specific applications. in particular, converter start-up at lower than specified temperature, wider input voltage range and output voltage adjustment are all relatively simple modifications to the standard product. consult factory for details. input output output input current (2) typical regulation model voltage (1) voltage current no load full load efficiency line (3) load (4) number 9-36vdc 5vdc 5000ma 20ma 1370ma 76% 0.5% 0.5% wp24s05/5000u 9-36vdc 12vdc 2500ma 20ma 1520ma 82% 0.5% 0.5% wp24s12/2500u 9-36vdc 15vdc 2000ma 20ma 1500ma 83% 0.5% 0.5% wp24s15/2000u 20-72vdc 5vdc 5000ma 20ma 680ma 77% 0.5% 0.5% wp48s05/5000u 20-72vdc 12vdc 2500ma 20ma 750ma 84% 0.5% 0.5% wp48s12/2500u 20-72vdc 15vdc 2000ma 20ma 740ma 85% 0.5% 0.5% wp48s15/2000u pin connections (5,6,7) pin function 1 + input 2 C input 3 + sense/trim down 4 output trim 5 C sense/trim up 6 + output 7 C output 8 remote on/off tolerance .xx = 0.02 .xxx = 0.005 10k w trimpot trim up trim down 5 4 3 5 4 3 25 to 30 watt wide input dc/dc converters dc/dc converters | 25-30w dc page 2 http://www.artesyn.com ds_wp_19980401.pdf
