CONVERTER / INVERTER – The UPS components which contain the equipment and controls
necessary to convert input AC power to output AC power required by the critical load.

regulate DC power required for battery charging and for supplying power to the Inverter.
BYPASS MODULE – The metal enclosure which contains the Bypass line, the Static transfer switch,
UPS operator controls, and internal control systems.
BYPASS LINE – The line which conducts electricity directly from the input power source to the critical
