Power Distribution and Protection Features
The GE IS200MVRPH1A IS200MVRPH1AED Power Distribution Board delivers clean power to all twelve rack slots. Each output rail has independent overcurrent protection with fuses. The board includes a two-stage filter for each voltage rail separately. Furthermore, it provides status feedback for each rail’s health condition. Consequently, the main controller knows exactly which rail has failed.
Installation and Connection Steps
Mount this GE IS200MVRPH1A IS200MVRPH1AED Power Distribution Board as the backplane inside any Mark VI rack chassis. First, connect the external DC supply to the two power input stabs. After that, secure the board using factory-installed standoffs and screws. Then, insert each VME card into its designated slot carefully. Finally, verify all rail voltages before powering up any other cards.
Energy Discharge and Safety Notice
This GE IS200MVRPH1A IS200MVRPH1AED Power Distribution Board stores significant energy in its capacitors. Therefore, you must wait at least three minutes after power removal. The six bulk capacitors discharge through internal bleeder resistors. Never insert or remove cards while the backplane remains powered.
Status Indication and Diagnostics
A green LED indicates the presence of valid input power on the board. Four yellow LEDs show the status of each output voltage rail. A red LED illuminates when any rail fuse has opened due to overload. These indicators help technicians verify power distribution without removing any cards.
