Description
Product Overview
The GE IS2020RKPSG2A VME Rack Power Supply Module is engineered for the Mark VI System, delivering regulated power to control and interface racks. It mounts on the right side of the VME rack using a sheet metal bracket and connects via PSA and PSB harnesses.
This module supplies +5, ±12, ±15, and ±28 Vdc to the VME backplane. It also offers an optional 335 Vdc output for flame detector circuits connected to TRPG. The unit supports two input voltage options: 125 Vdc from a Power Distribution Module (PDM) or a low-voltage 24 Vdc version.
Each of the five internal 28 Vdc modules powers a specific rack section labeled A through F. The P28C output can also support external peripherals when configured via jumper settings. A fan connector powers cooling only when a controller is installed.
