CARD RACK POWER SUPPLY
OPERATING INSTRUCTIONS:
I. General:
The Models Q-2 and Q-4 power supplies transform 120/240 VAC, 50/60 Hz
input power into unregulated 24 VDC outputs. Each output is rated for 300 mA
of load current and can be paralleled (via the rack wiring) for increased current
capability. The Model Q-2 has two outputs and the Model Q-4 has four outputs.
The Models Q-2 and Q-4 have four configurations: 120 VAC 50 Hz, 120 VAC
60 Hz, 240 VAC 50 Hz, and 240 VAC 60 Hz. Your input voltage and frequency
must match your need.
Please verify rack wiring before applying power.
Turn the power switch OFF whenever removing or inserting the power supply
module.
