DS200FSAAG2ABA General Electric FIELD SUPPLY AMPLIFIER DS200FSAAG2A

The control cabinet can accept power from multiple power sources. Each power input source (30 A / 120 V ac, 15 A / 240 Vac, or 30 A / 125 V dc) should feed through its own external, two-pole, thermal, magnetic circuit breaker before entering the control system enclosure. The breaker should be supplied in accordance with required site codes. The circuit breaker must be included in the installation. If used as the panel disconnect, it must be suitably located and easily reachable. The circuit breaker must be marked as the disconnecting device and suitably located near the equipment for servicing.Mark VIe control cabinets / systems may use up to three mains supplies; two for redundant control power (ac and / or dc) and one auxiliary ac supply for accessories such as cabinet lights and fans. The following are example mains power supply rating labels used on the front cabinet door where the panel main power is to be connected.

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.
