Product Data Sheet
500 WATT AC/DC POWER SUPPLY
PX500
DESCRIPTION
The PX500 is a compact 500 watt Power Factor Corrected, multiple output power supply. All outputs are fully isolated and regulated. Active current sharing circuitry, together with control functions and alarm options, simplifies N+1 and redundant applications. Fan and disk drive applications are handled by the peak current ratings of the auxiliary outputs.
FEATURES
! Active Power Factor Correction ! High Surge Current Auxiliary Outputs ! Fully Isolated Outputs ! One, Two, Three or Four Output Models ! N + 1 Current Sharing ! FCC/VDE Class B EMI Filter Standard ! Fast Transient Response ! Optional Cover With Fan

Remote Sense Remote Sense is provided on Output #1 and will compensate for 1.0V of line drop. Remote Sense leads are protected against open, short and reversal. Remote On/Off (Optional) The power supply is turned on with a TTL logic `1' (or open) signal and turned off by a switch closure or TTL logic `0' referenced to (-) sense terminal. Consult the factory for other options. Over Voltage Protection Output #1: 6.5V, 0.5 VDC The power supply will latch off until AC power is cycled. Over Current Protection Individual current limit on all outputs. Automatic recovery upon fault removal. Transient Response The peak output voltage excursion will not exceed 2% and will recover within 1% in 400 sec for a 25% step load. Output Isolation All outputs are fully isolated.
N+1 Load Share Output #1 has active load sharing circuitry. Units will load share within 1.0% of Maximum Rated Load. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 5msec before loss of DC output. Upon AC input turn-on, signal remains low until outputs are in regulation. Consult the factory for other options. Over Temperature Protection Internal thermal switch turns off power supply if overheating occurs and automatically restarts. Automatic restart when temperature drops below threshold. Safety UL Recognized: UL File Number E14675 (1950 & 1012) CSA Certified: CSA File Number LR 9070-154C (C22.2 No9. 234-M90, Level 6) TUV License Number: R9576030 (EN60950) (IEC950) Cooling The unit is designed to operate with 40 CFM of airflow.
