Product Description:

The CS0174100020-05 is a power electronics card from B & R Automation that fits into the CS0 Motherboard Module Cards series. Within a control cabinet, the card hosts an IGBT inverter stage, a rectifier bridge, and an integrated cooling fan so that drive power can be mounted directly beside logic modules. In an automation line, it delivers the switching, rectification, and temperature sensing needed to run compact servo or spindle drives without adding discrete components.

The fan uses a supply of 24 V, draws 0.21 A through two-wire leads, and occupies a compact 60 × 60 × 25 mm footprint to move air across the heat spreader. Gate control nodes tolerate ±20 V, and the input capacitance of 1.5 nF shapes the turn-on waveform. On the power side, the IGBT collector can withstand 1200 V; its switching channel carries up to 45 A in short bursts while the continuous inverter rating is 25 A. An isolation barrier of 2.5 kV separates the power stage from signal tracks so the motherboard backplane remains at SELV potential. The rectifier diodes allow 1600 V reverse stress for three-phase mains. This combination suits medium-power drive sections used on 400 VAC supply systems where compact power conversion hardware is installed beside control modules.

The junction temperature limit is 150 °C, monitored by an onboard NTC that reads 5 kΩ at 25 °C and follows a 3375 K B-value curve. Mechanical retention uses M4 fasteners tightened to 3 Nm, ensuring stable thermal contact between the module body and its heat sink. Despite integrating inverter, rectifier, fan, and sensors, the assembly weighs only 180 g, reducing mass on slide-in racks. The onboard temperature signal supports continuous thermal monitoring, and the combined inverter and rectifier functions keep the cabinet layout compact without requiring separate power-stage modules.
