AP-1294 ISOLATED INTERFACE BOARD FOR POWEREX DUAL IPM MODULES

The AP-1294 provides a complete, tested, fast time-to-market solution for customers who need to interface to POWEREX Third Generation Dual IPM modules.

The AP-1294 incorporates two isolated DC-DC converters which supply power to the IPM module. High speed optocouplers provide the proper interface between the module and the customers’ control electronics. The assembly provides direct mounting to the IPM module and is packaged in a small footprint printed circuit board that measures only 2.50” X 4.30”.

The AP-1294 supports the following IPM modules:

PM75DSA120
PM100DSA120
PM200DSA060
