AB5 - A metal alloy (e.g., LaNi5) capable of undergoing a reversible hydrogen absorption/desorption reaction as the battery is charged and discharged, respectively.
Filter (phase-shift) - Filter used to reduce, if necessary, the overall distortion due to the current harmonics injected into the mains upstream of a UPS by its rectifier-charger. Filtering is superior to that of a traditional filter of the L or C type.
Internal Impedance - The opposition exhibited by a circuit element (cell or battery) to the flow of an alternating current (a.c.) of a particular frequency as a result of resistance, induction and capacitance.
Drain - The current withdrawn from a battery during discharge.
Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
Thermostat - A temperature sensitive switch.
Bypass (automatic) - In the event of an overload or an unlikely UPS problem, your application is still powered, thanks to the automatic bypass module.
