GE Mark VIe System Manual page 133

Power requirements for a typical large, four-cabinet turbine control containing controllers, I/O, and terminal boards are
displayed in the following table. The total cabinet current ratings must include the current supplied to external loads, such as
solenoids and ignition transformers as described in the notes below the table. Heat dissipation in a typical TMR turbine
control is about 1600 watts. However, power supply mains and heat dissipation requirements must be calculated for each
Mark VIe cabinet application based on the number and mix of controllers, I/O modules, IONet switches, power supplies, and
external loading.
Cabinet
Large, 125 V dc
four-cabinet 120 V ac
turbine control 240 V ac
1.
Add 0.5 A dc † continuous for each 125 V dc external solenoid powered.
2. Add 6.0 A rms † for a continuously powered ignition transformer (2 maximum).
3. Add 3.5 A rms † for a continuously powered ignition transformer (2 maximum).
4. Add 2.0 A rms † continuous for each 120 V ac external solenoid powered (inrush 10 A).
Note
† These are external and do not create cabinet heat load.
