I/O modules

The DS200GSIAG1C DS200GSIAG1CFD manages regenerative energy on the common DC bus for GE Mark V drives. This board recovers braking energy and returns it to the power supply. You can rely on it for energy efficiency and system stability.

Key Technical Parameters

The table below lists all essential technical specifications for this common DC bus regenerative board.

Physical Characteristics and Installation

This regenerative board weighs approximately 0.65 kg for secure rack mounting. Its dimensions measure 280 mm x 80 mm x 25 mm for Mark V drive racks. First, align the DS200GSIAG1C DS200GSIAG1CFD with the backplane connectors. Then, press firmly until the board seats completely. Finally, secure the board using the top and bottom retaining screws. A conformal coating protects the PCB from moisture and dust.

Regenerative Power Specifications

The DS200GSIAG1C DS200GSIAG1CFD handles a common DC bus voltage from 400V to 750V DC. This board regenerates up to 50 kW of braking energy back to the AC line. The switching frequency operates at 4 kHz for efficient power conversion. Voltage-sourced control maintains stable DC bus regulation. The board returns excess energy during motor deceleration. Consequently, this design reduces energy waste and cooling requirements.

Protection Features and Component Layout

This regenerative board includes overcurrent protection at 150% for 10 seconds. The control logic monitors DC bus voltage and current continuously. A fault signal triggers the regenerative inverter during abnormal conditions. The board contains 15 integrated circuits for gate drive and control logic. Thirty capacitors provide filtering and energy storage. Twenty-five resistors establish proper timing and feedback levels. The DS200GSIAG1C DS200GSIAG1CFD units share identical electrical specifications. The “CFD” suffix indicates a revised PCB layout or newer component revision.
