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. DS200GDPAG1A DS200GDPAG1AGC weighs exactly 2.1 kg for robust mechanical stability. You will find 112 discrete components on a six-layer PCB.
Moreover, the board integrates a 3300 µF primary bulk capacitor bank. This bank stores energy and filters ripple from the DC input line. It also provides a 30 ms hold-up time during input voltage sags.
High-Frequency Switching Design
A pair of MOSFETs switches at 80 kHz for power conversion. This high frequency reduces the size of the main transformer significantly. The board uses a ferrite core transformer for minimal core losses. Consequently, the power supply achieves 88% efficiency across most load 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 and remote sense lines. Two 10-pin auxiliary connectors carry status signals and fault indicators. Furthermore, four LED indicators show input presence, output OK, and overtemperature warnings.
Thermal Management and Cooling
A passive extruded aluminum heat sink covers the MOSFETs and diodes. This design removes heat without requiring any forced-air cooling fans. Therefore, the board operates reliably in sealed turbine control cabinets. The thermal pad between components and sink ensures efficient heat transfer.
Typical Application Scenarios
You can deploy DS200GDPAG1A DS200GDPAG1AGC in gas turbine high-frequency power distribution panels. It also works well for steam turbine excitation systems and servo drives. This board powers sensitive analog circuits and digital I/O modules. Its high switching frequency produces minimal audible noise during operation.
