GE DS200FHVAG1A DS200FHVAG1ACA SCR High Volt Gate Interface Board

The GE DS200FHVAG1A DS200FHVAG1ACA belongs to the Mark V series. General Electric designed this board as an SCR gate driver. This component triggers high-voltage thyristors in power converters. It also provides isolation between control and power circuits.

Technical Specifications

The table below lists all key parameters for the GE DS200FHVAG1A DS200FHVAG1ACA.

SCR Gate Drive Features

The GE DS200FHVAG1A DS200FHVAG1ACA uses a rugged six-layer PCB. Over 145 resistors, capacitors, and pulse transformers drive SCR gates. A single 64-pin DIN connector links this board to the backplane. Consequently, firing pulses reach high-voltage thyristors reliably. Three onboard LEDs show power, gate activity, and fault status. Moreover, film capacitors store energy for high-current gate pulses.

Input and Output Capabilities

You get six fiber optic receiver inputs on this gate interface board. These inputs receive firing commands from the main controller. The GE DS200FHVAG1A DS200FHVAG1ACA provides six isolated SCR gate drive outputs. Each channel delivers up to 2 amps of peak gate current. Therefore, this board triggers large thyristors in high-power applications.

Isolation and Protection

Each gate drive channel provides 2500 V RMS of galvanic isolation. Fiber optic inputs eliminate electrical connections to the control side. The GE DS200FHVAG1A DS200FHVAG1ACA also includes snubber circuits on each output. As a result, the board survives high dv/dt transients from power circuits.

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 DS200FHVAG1A DS200FHVAG1ACA. Ceramic capacitors filter high-frequency noise on power lines. Film capacitors store energy for high-current gate pulses. Consequently, the board delivers consistent gate drive under all load conditions.

Mechanical Layout

This SCR gate interface 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 high-voltage board by its edges. This precaution prevents electrostatic discharge damage.

Installation Context

This board works alongside other Mark V power supply and control cards. Its compact size allows easy placement near SCR stacks. The robust design handles continuous high-voltage switching. Choose the GE DS200FHVAG1A DS200FHVAG1ACA for your SCR gate drive needs.
