Voltage Depression - An abnormal drop in voltage below expected values during the discharge of a battery.
Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
RMS Voltage - The range of usable voltage + or - 170 VAC.
Passivation - The phenomenon by which a metal, although in conditions of thermodynamic instability, remains indefinitely unattacked because of modified or altered surface conditions.
RS232C (Recommended standard RS232C) - Standard defining the communication circuits between devices for synchronous and asynchronous transmissions on the following types of lines - two-wire, four-wire, point-to-point, telephone lines and local links with short cables. Though the standard covers only transmissions over distances up to 15 meters, it is often possible to ensure correct transmission over greater distances using high-quality shielded cable in a reasonably satisfactory electrical environment. Most terminals and devices on the market can implement this transmission standard.
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
Inverter (on-line) - UPS configuration in which the inverter is in series mounted between the mains and the load. All power drawn by the load passes via the inverter. This is the only configuration used for high outputs.
