Physical Construction and Component Layout
This DS200UPSAG1A DS200UPSAG1ADB power control board measures 8.5 inches in length. Its width reaches 5.9 inches with a thickness of 1.6 inches. The total weight comes to approximately 1.75 pounds. Manufacturers placed 278 discrete components on this six-layer PCB. These components include pulse transformers, optocouplers, phase detectors, and timing circuits. Both DS200UPSAG1A and DS200UPSAG1ADB share the same power control design.
Control Channels and Output Specifications
DS200UPSAG1A DS200UPSAG1ADB provides 12 independent power control channels. Each channel delivers adjustable pulse widths from 10 to 180 microseconds. Output current reaches 200 milliamps per channel for reliable SCR triggering. Optical isolation withstands 2500V RMS between logic and power sections. The board accepts standard 24V DC logic signals for input control. Firing angle adjusts continuously from 0° to 180° of the AC cycle. Consequently, this board controls power delivery with high precision.
Timing Control and Protection Features
DS200UPSAG1A DS200UPSAG1ADB uses phase-locked loop for line synchronization. The PLL locks to the AC line frequency automatically. Shoot-through prevention circuitry blocks overlapping firing pulses. This protection prevents short circuits across the DC bus. Twelve green LED indicators show active firing status per channel. Each LED illuminates when the corresponding channel receives a firing command. Therefore, technicians can verify output activity at a quick glance.
Energy Storage and Application Use
DS200UPSAG1A DS200UPSAG1ADB integrates six 470µF capacitors for bulk energy storage. Eight additional 100µF capacitors filter high-frequency power noise. The board draws 300 milliamps at 5V and 150 milliamps at 24V. You will find this board in GE power control and SCR drive systems. It generates firing pulses for thyristor stacks in AC and DC drives. The board operates reliably from 0°C to 55°C ambient temperature. For example, it controls large motor starters or heating elements. Therefore, this power control board provides precise phase control for industrial power applications.
