Current loop (20 mA) - Transmission system used on certain devices and offering better performance than the RS232C. It provides a high degree of immunity to interference and is easy to implement, but has not been standardized.
Bypass (automatic) - In the event of an overload or an unlikely UPS problem, your application is still powered, thanks to the automatic bypass module.
Coulomb - The amount of electricity transported by a current of one ampere flowing for one second.
Anode - The electrode in an electrochemical cell where oxidation takes place. During discharge, the negative electrode of the cell is the anode. During charge, the positive electrode is the anode.
Output (rated) - Apparent power Pn that the UPS can deliver under given load conditions (power factor = 0.8).
Working Voltage - The typical voltage or range of voltage of a battery during discharge (also called operating voltage or running voltage).
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.
