Physical Dimensions and Component Layout
This board measures 26.0 cm in length and 18.5 cm in width. Its total height reaches 5.5 cm including the heat sink assembly. DS200GDPAG1A DS200GDPAG1AJF weighs exactly 2.1 kg for stable mounting. You will find 112 discrete components on a six-layer PCB with ground planes.
Furthermore, the board integrates a 3300 µF primary bulk capacitor bank. This bank stores energy and filters ripple from the DC input line effectively. It also provides a 30 ms hold-up time during momentary input sags.
High-Frequency Switching Topology
A pair of power MOSFETs switches at 80 kHz for efficient conversion. This high frequency allows the main transformer to remain physically small. The board uses a ferrite core transformer for minimizing eddy current losses. Consequently, the power supply achieves 88% efficiency across most operating ranges.
Connector Interfaces and Signal Routing
The front panel provides one 4-pin terminal block for DC input connections. A separate 6-pin header delivers the 24V output plus remote sense lines. Two 10-pin auxiliary connectors carry status signals and fault indicators to the controller. Moreover, four LED indicators show input presence, output OK, and overtemperature warnings.
Thermal Management and Cooling Approach
A passive extruded aluminum heat sink covers the MOSFETs and rectifier diodes. This design removes heat without requiring any forced-air cooling fans. Therefore, the board operates reliably in sealed turbine control cabinets without noise. The thermal interface pad between components and sink ensures efficient heat transfer.
Typical Application Scenarios
You can deploy DS200GDPAG1A DS200GDPAG1AJF in gas turbine high-frequency power distribution panels. It also works well for steam turbine excitation systems and servo drive power supplies. This board powers sensitive analog circuits and digital I/O modules reliably. Its high switching frequency produces minimal audible noise during normal operation.
