Physical Construction and Component Layout
This DS200RTBAG5A DS200RTBAG5AHC excitation board measures 10.2 inches in length. Its width reaches 6.9 inches with a thickness of 2.4 inches. The total weight comes to approximately 2.35 pounds. Manufacturers placed 224 discrete components on this heavy copper PCB. These components include SCR bridges, firing circuits, PID controllers, and protection relays. Both DS200RTBAG5A and DS200RTBAG5AHC share the same excitation control design.
Excitation Output and Field Regulation
DS200RTBAG5A DS200RTBAG5AHC delivers up to 90V DC at 15 amps for field excitation. The output voltage adjusts continuously from 0 to 90V DC. A PID closed-loop regulator maintains precise field current control. The control input accepts either 4-20 mA or 0-10V command signals. Response time reaches 50 milliseconds typical for dynamic regulation. Accuracy stays within ±0.5% of the setpoint value. Therefore, this board provides stable excitation for synchronous machines.
Protection Features and Status Indication
DS200RTBAG5A DS200RTBAG5AHC includes comprehensive protection for safe operation. Overcurrent protection shuts down the output during field faults. Overvoltage protection prevents damage from regenerative conditions. Six LED indicators show critical operational status clearly. Green LEDs indicate power and regulation active status. Red LEDs illuminate for overcurrent or overvoltage faults. The board accepts either 120V AC or 240V AC input power. Total power draw reaches 250 VA under full load conditions.
Energy Storage and Application Use
DS200RTBAG5A DS200RTBAG5AHC integrates four 2200µF capacitors for bulk storage capacity. Six additional 470µF capacitors filter ripple from the excitation output. Natural convection cooling eliminates the need for fans. You will find this board in GE generator excitation and motor control systems. It supplies field current for synchronous motors and alternators. The board operates reliably from 0°C to 55°C ambient temperature. For example, it excites large industrial generators or synchronous drives. Therefore, this power excitation board delivers reliable field control for rotating electrical machines.
