4.2.5 POWER SUPPLY ASSY: PS2001-XX
The NV3128 Frame and its Power Supply are UL listed. The Power Supply Module
AC Power enters the system through connectors mounted on the rear panel. In addition to providing an AC connection, each connector contains both a 1.6 ampere fuse and a Radio Frequency Interference (RFI) /Electromagnetic Interference (EMI) filter.
This
A single PS2001 can safely supply the NV3128. A second may be added for redundancy.
CAUTION: HIGH VOLTAGES EXIST IN THE INPUT AND RECTIFIER CIRCUITRY. ALWAYS USE CAUTION WHEN HANDLING COMPONENTS IN THESE DANGEROUS AREAS.
The AC input voltage is rectified by diodes and filtered by capacitors.
This provides raw DC at a high voltage.
CAUTION: THE SETTING OF J1 SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL ONLY.
The power input source and jumper location must be consistent.
Jumper J1 is set at the factory for either 115 VAC or 230VAC.
ALWAYS CHECK FOR THE CORRECT SETTING BEFORE
APPLYING POWER TO THE UNIT IN A NEW INSTALLATION.
When the jumper is in the 115 VAC position, the input circuit acts as a voltage doubler. The raw DC output is the sum of the positive and negative
The power supply module incorporates several protective elements. A common problem with
