Description
The ABB JINT-B2C Main Circuit Board is a medium-voltage phase module engineered for ACS 2000 3.3 kV / 630 kW drives, serving as one of three identical modules per inverter. It integrates high-current IGBTs (1,200 A / 6.5 kV, four in parallel) to achieve reliable power conversion at nominal switching frequencies of 500 Hz, with a maximum of 1 kHz. The board supports continuous operation at 125 A per phase, delivering approximately 630 kW at 50 Hz with a power factor of 0.95.

The DC-bus operates at roughly 4.6 kV after rectification, and the module includes an aluminum fin heatsink with forced air cooling, maintaining a thermal resistance ≤ 0.08 K/W. Temperature monitoring is provided by two PT100 sensors with 2 mm plug-in connectors, ensuring accurate thermal protection of the IGBT modules.

For precise switching, the board incorporates fiber-optic firing interfaces with two HFBR-1528 receivers and two HFBR-2528 transmitters. The fan interface supports 24 V DC / 2 A power with open-collector speed feedback to manage thermal load efficiently.

Designed for industrial environments, the JINT-B2C operates safely within 0 °C to +40 °C with forced air cooling, and can be stored between −40 °C and +70 °C. It is rated IP42 at the front and IP20 at the rear, suitable for installation at altitudes ≤ 1,000 m without derating. The module meets CE, IEC 61800-4, and RoHS standards, with main-to-earth withstand of 18 kV for 1 minute.
