GE DS200DSFBG1A DS200DSFBG1AEB Driver Shunt Board

Key Technical Specifications

This GE DS200DSFBG1A DS200DSFBG1AEB driver board monitors 600V DC bus voltage levels. It measures 100A shunt current for drive feedback applications. The unit measures 21 cm in length, 16 cm in width, and 4.5 cm in height. Its total weight reaches 0.85 kg without any packaging materials.

The GE DS200DSFBG1A DS200DSFBG1AEB includes one precision shunt resistor for current sensing. Additionally, it features two isolated amplifier circuits for voltage and current feedback. A single 6-pin terminal block connects the shunt and bus voltage inputs. The board contains 1 shunt resistor, 2 isolation amplifiers, 3 op-amps, 12 resistors, and 8 capacitors.

GE DS200DSFBG1A DS200DSFBG1AEB stores energy using two ceramic capacitors. Together, they provide 10 µF at 100V rating for input filtering. This arrangement removes high-frequency noise from shunt measurements. Therefore, the board delivers clean feedback signals to the drive controller.

Design and Integration

Both the GE DS200DSFBG1A and DS200DSFBG1AEB versions share identical sensing topology. These boards use four-layer PCB construction with isolated analog and digital grounds. Consequently, the GE DS200DSFBG1A DS200DSFBG1AEB operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 50 mA typical current from a 15V DC auxiliary supply. The shunt can carry 150A overload for up to 1 second. We recommend using 6 AWG wire for the main shunt connections.

Practical Application

This driver shunt board reports DC bus current and voltage to a motor drive controller. It senses current through the external shunt resistor with high accuracy. The GE DS200DSFBG1A DS200DSFBG1AEB then sends isolated analog signals to the regulator board. Therefore, it enables precise torque and speed control in DC drive systems.
