Manual bypass switches are an added benefit to allow service and isolation for safety purposes. Correctly designed systems should enable these operations to be performed without loss of power to the load.
What is UPS static switch?
While the UPS is on-line, using either mains or battery power, the static switch is in ‘On UPS’ state, connecting the inverter output to the load. When supplies return to normal, the static switch automatically transfers the load back to bypass while the battery recharges and the inverter reverts to standby mode.
What is inverter bypass?
The bypass switch allows the owner to send power to inverted loads (usually electrical outlets, heaters, dehumidifiers etc.), by sending electric current around the inverter.
