The PX400 is a compact 400 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 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
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 Voltag e 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 200 µsec for a 25% step load.
Output Isolation
All outputs are fully isolated.
Reverse Voltage Protection
All outputs are protected to rated load current.
Power Fail Signal
Upon AC input voltage removal, the power fail signal drops
to logic zero at least 10msec before loss of DC output.
Upon AC input turn-on, signal remains low until outputs are
in regulation. Consult the factory for other options.
N+1 Load Share (PX402)
Output #1 has active load sharing circuitry. Units will load
share within 1% of the Maximum Rated Load.
Over Temperature Protection
Thermal switch turns off power supply if overheating occurs
and automatically restarts.
