Excitation Control Features

The GE DS200EXDEG1A DS200EXDEG1ADA uses a rugged four-layer PCB. Over 150 resistors, capacitors, and precision op-amps regulate field current. A single 64-pin DIN connector links this board to the backplane. Consequently, excitation commands reach SCR gates within microseconds. Four onboard LEDs show power, regulation, limit, and fault status. Moreover, film capacitors provide stable energy for gate drive circuits.

Feedback and Output Capabilities

You get six SCR gate drive channels on this excitation board. These channels control three-phase bridge rectifiers. The GE DS200EXDEG1A DS200EXDEG1ADA accepts three phase potential transformer inputs for voltage feedback. Three current transformer inputs monitor field current. Therefore, this board maintains generator voltage within ±0.5% accuracy.

Power and Energy Storage

You must install this board inside a protected Mark V cabinet. The backplane supplies 5 VDC and 24 VDC to the GE DS200EXDEG1A DS200EXDEG1ADA. Aluminum electrolytic capacitors store energy for short hold-up during transients. Film capacitors filter noise on analog feedback lines. As a result, the board delivers precise excitation control consistently.

Mechanical Layout

This excitation control board measures exactly 25.4 cm in width. Its height reaches 17.8 cm. The total weight equals just 0.45 kg. As a result, this board saves valuable rack space. The lightweight design also reduces stress on the backplane connector. Always handle this excitation board by its edges. This precaution prevents electrostatic discharge damage.

Installation Context

This board works alongside other Mark V power supply and I/O cards. Its compact size allows easy placement near generator control panels. The robust design handles continuous industrial excitation. Choose the GE DS200EXDEG1A DS200EXDEG1ADA for your generator excitation control needs.
