External Maintenance Bypass Switches (MBS)

Typical 10-40 KVA Bulkhead Mount MBS

In applications where external MBS are required in harsh environment, industrial grade products often fall short in being able to withstand high shock, vibration, and humidity for extended periods of time. Now, the same standalone MBSs previously only supplied with Nova’s military power conversion equipment are available for purchase on their own. Rack mount and bulkhead mount versions are available, all featuring the same ruggedized construction that allows our supplies to be qualified to MIL-STD-810, MIL-S-901, MIL-STD-167 and other related environmental standards.

When used with one of our UPS systems, the External Maintenance Bypass Switch allows the complete removal of power from the UPS system for safe service and maintenance, while maintaining power to the load.
