PLCs, Power Supplies & Others

The GE DS200LUVAG1A DS200LUVAG1AEC manage voltage regulation for GE Mark V turbine systems. These module controllers oversee generator excitation and power factor control. You can use either controller for automatic voltage regulation (AVR) functions. The units provide precise voltage control for synchronous generators.

Control and Electrical Specifications

The GE DS200LUVAG1A DS200LUVAG1AEC support automatic voltage regulation and power factor control. These module controllers accept potential transformer inputs from 0 to 150 VAC. You can switch between AVR, FCR, VAR, or power factor modes seamlessly. The units output ±10 VDC signals to SCR gate drive boards.

Physical Dimensions and Weight

Each module controller weighs 0.52 kg for secure chassis mounting. The unit measures 280 mm long by 178 mm wide. Its PCB thickness reaches 1.6 mm with six internal copper layers. You can mount either controller using six M4 screws through the designated holes.

Interface and Connection Points

Three 50-pin ribbon cable headers connect to the main turbine backplane. Two 6-pin terminal blocks handle PT and CT input wiring. The GE DS200LUVAG1A DS200LUVAG1AEC include a 4-pin connector for control output signals. You will find eight LED indicators showing mode and fault status. Additionally, twelve test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These module controllers store moderate energy for control stability. Eighteen electrolytic capacitors provide 1,200 µF of total bulk storage. These capacitors smooth power supply ripple for the analog circuits. The controllers do not contain any battery for configuration retention. An onboard EEPROM stores calibration and tuning parameters permanently.

Component Layout and Construction

A dedicated 32-bit DSP handles all control algorithm calculations. Six precision operational amplifiers condition PT and CT input signals. You will find 148 resistors, 96 capacitors, and 14 integrated circuits on the board. The GE DS200LUVAG1A DS200LUVAG1AEC include over-excitation and under-excitation limiters. A metal shield covers the analog section for noise reduction.

Variant Equivalence and Use

The GE DS200LUVAG1AEC represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these controllers restores voltage regulation to Mark V systems. Use GE DS200LUVAG1A DS200LUVAG1AEC for generator excitation control in power plants. For best results, verify PT and CT wiring polarity before commissioning.
