RMS Voltage - The range of usable voltage + or - 170 VAC.
Cubicle (parallel UPS unit) - Cubicle containing a rectifier/charger and an inverter. It is connected to one or several other identical cubicles and a bypass cubicle to make up a parallel UPS.
Polarization - The lowering of the potential of a cell or electrode from its equilibrium value caused by the passage of an electric current.
Pulse Current - A periodic current drain of higher than normal drain rates.
Power source (alternate) - Backup source used in the event of a mains failure. The connection time and the duration of the source depend on the type of source used. (back)
Voltage-Keyed - A system which incorporates a mechanical identifier on batteries and devices to ensure only batteries of the correct voltage are connected to the device.
Voltage Depression - An abnormal drop in voltage below expected values during the discharge of a battery.
