Eaton mVEC Multiplexed Vehicle Electrical Center

CAN Network Oversight for High Power Circuits in Vehicle Power Distribution.

The Eaton Multiplexed Vehicle Electrical Center (mVEC) offers economical CAN Network oversight for high power circuits in vehicle power distribution. Rated at 200 amps, the mVEC can be configured to provide various OEM circuit protection and switching functions, using industry standard fuses, relays, and breakers, with the status and control of each circuit accessible through J1939 CAN-open messages. The mVEC is offered in various standard and customized versions, with custom versions being configured to OEM wiring requirements.
