KX500 8/99 REV B
Page 1
DESCRIPTION
The KX500 is a compact 500 watt Power Factor Corrected, multiple
output power supply. All outputs are fully isolated and regulated.
The main +5V output delivers 80A with remote sensing. Five
outputs allow this one power supply to fill all system voltage
requirements, including fan and disk drive applications. Both
Power Fail Warning and DC OK signals are standard features as
well as Remote Inhibit.

Remote Sense
Remote Sense is provided on Output #1 and will
compensate for 0.3V 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 level `1' (or
open) signal and turned off by a switch closure or TTL logic
level `0' referenced to (-) sense terminal. Consult the factory
for other options.
Over Voltage Protection

.
Output #2: 14.0V 1V

. (Output #2 12V)
17.0V 1V

. (Output #2 15V)
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.
Reverse Voltage Protection
All outputs are protected to rated load.
Transient Response
The peak output voltage excursion on the main output will
not exceed 2% and will recover within 1% in 50 mSec for a
25% load step change. On outputs #2-5, the peak output
voltage excursion will not exceed 1% for a 25% load step
change.
Output Isolation
All outputs are fully isolated.
Power Fail Signal
Upon AC input voltage removal, the power fail signal drops
to logic level `0' 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.
DC Power Good Signal
The signal drops to logic level `0' by a 10% loss of regulation
on any output, common with Output #1 (-) sense. 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.
