I/O modules

The DS200DACAG1A DS200DACAG1ACC converts 240V AC input into regulated 125V DC output. This board delivers clean DC power for Mark V turbine control systems. It operates with 95% efficiency at full load conditions.

Key Technical Specifications

Physical Layout and Component Configuration

This board measures 22.5 cm in length and 16.0 cm in width. Its total height reaches 4.5 cm including all components. DS200DACAG1A DS200DACAG1ACC weighs exactly 1.8 kg for secure mounting. You will find 94 discrete components on a six-layer PCB.

Moreover, the board integrates a 4700 µF DC link capacitor bank. This bank stores energy and smooths the rectified DC waveform. It also provides a 40 ms hold-up time during input brownouts.

Connector Interfaces and Signal Routing

The front panel provides one 3-terminal AC input connector for field wiring. A separate 4-terminal DC output block carries the 125V DC power. Two 10-pin auxiliary connectors send voltage and current feedback signals. A grounding terminal also sits near the bottom edge for safety.

Thermal Management and Cooling Design

A passive aluminum heat sink covers six power diodes and IGBTs. This design removes heat without any forced-air cooling fans. Therefore, the board runs silently in sealed industrial cabinets. The four mounting holes allow secure attachment to any flat surface.

Typical Application Scenarios

You can deploy DS200DACAG1A DS200DACAG1ACC in gas turbine excitation systems. It also works well for steam turbine control panels and drives. This board supplies stable 125V DC power to field coils. Its high efficiency reduces waste heat in dense cabinets.
