Solidstate Controls’ RS Series Remote Manual Bypass Switch (RMBS) is a 3-position switch that allows for complete isolation of a UPS or inverter while performing routine or emergency maintenance on the equipment.
The load is temporarily transferred from the inverter (UPS) onto the bypass (alternate) AC power source. This “make-before-break” switch is designed to transfer between two in-sync sources to enable a zero-break transfer in both directions, so there is no disruption of power to the connected load(s).
