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.

Remote Sense
Remote Sense is provided on Output #1 and will com-
pensate 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 V
DC
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 over-
heating occurs and automatically restarts. Automatic
restart when temperature drops below threshold.
