POWER SUPPLY MODULE
8.10.1
DESCRIPTION
The 2000 PS series of power supply modules are the power source for all logic circuits in the RFL
9508D, and are available in both dc-input and ac-input versions. 50 watts of output power is available.
The high power model will give 75 watts of output power.
Input fusing and output overcurrent protection are provided as safety features. In addition the supplies
are designed to meet the Oscillatory, and fast transient tests specified in IEEE C37.90.1-2002.
There are two types of power supplies that can be used with the 9508D Digital Chassis, as shown in
Table 8-16. The 9508D Digital Chassis can be powered with either one or two Power Supply modules.
The first power supply is inserted into the "P.S. MAIN" slot. The second, optional, power supply is
inserted into the "P.S. REDUNDANT" slot. The second power supply, if installed, provides power
supply redundancy. If the main power supply fails, the redundant supply automatically comes on-line
with no interruptions.
If you are adding modules to an existing system equipped with dual power supplies, always verify that
total power consumption does not exceed the capacity of a single supply. This will insure power
supply redundancy.
