VMIVME-7807 Gas turbine module industry application

DC power is connected to the System 57 via the DC Input Card terminal block TB1. The DC Input Card provides diode isolation to permit the connection of two separate power supplies. eg. A mains derived dc power supply and battery backup dc supply. Note that current will be drawn from the supply input with the highest voltage and in some circumstances current will be shared between the two inputs. Each of the two inputs have twin +24V and 0V terminals for easy through power connection or paralleling of input sources. A fused +24V output, which is the combination of both dc inputs, is provided for powering ancillary devices.

Individually Powered Control CardsNote: In individually powered control systems a DC connection is still required to the DC Input Card in order to provide power to the Engineering Card. Individually powered control cards may be required where the local or other regulations dictate individual connections in order to achieve the highest integrity for power distribution.

AC TO DC POWER SUPPLY UNIT CONNECTIONS

The input supply to the AC to DC Power Supply Unit may be: a. an ac supply of 85V to 264V at 47Hz to 440Hz. b. a dc supply of 110V to 340V (Refer to Zellweger Analytics for information on dc supplies). The supply must be fused at 6A maximum at the supply source. eg. At the distribution panel. Where additional cabling is used this must be mains rated for a minimum of 6A. Two cables emerge from the rear of the AC to DC Power Supply Unit: a. AC Input The ac supply cable connections are colour coded BROWN - LIVE, BLUE - NEUTRAL and YELLOW/GREEN - EARTH. If necessary, these wires should be connected to the ac supply via a suitable intermediate mains rated terminal block. b. DC Output The dc output cable connections are colour coded RED - +24V and BLACK - 0V. These should be connected to the appropriate DC Input Card terminals.
