Power Supply Module
Power Supply Module Description
The power supply module converts a quasi-square wave, 50 – 60 Hz AC input
voltage into four well-regulated DC output voltages. The supply is an off-line,
switched-mode power supply with a large operative input range. This reduces
service outages by converting long duration AC surges into load power. The power
supply is a constant power device, meaning that it automatically adjusts its internal
operating parameters for the most efficient use of the different levels of input voltage
and current it will receive within the cable plant.
The DC output voltages generated by the power supply, at given load currents, are
shown below:
+24.5 VDC @ 6.2 Amps
+8.5 VDC @ 1.0 Amps
+5.5 VDC @ 1.3 Amps
-6.0 VDC @ 0.8 Amps
Test points are provided on top of the power supply module for AC input and all
output DC voltage rails.
