UPS (parallel without redundancy) - A UPS made up of several (n) parallel-connected UPS units with equal output ratings (P) and each equipped with its battery, for large loads. The total output is equal to the number of units multiplied by their individual output (n x P). In this configuration, no UPS unit is redundant.
Intermittent Test - A test during which a battery is subjected to alternate periods of discharge and rest according to a specified discharge regime.
Critical Load - Devices and equipment whose failure to operate satisfactorily jeopardizes the health or safety or personnel and/or results in loss of function, financial loss, or damage to property deemed critical by the user.
RMS Voltage - The range of usable voltage + or - 170 VAC.
Brownout - A steady state RMS voltage under nominal by relatively constant percentage.
Midpoint Voltage - The voltage of a battery midway in the discharge between the start of the discharge and the end voltage.
Noise level - Acoustical decibel level of a source of noise, measured according to the applicable ISO standard.
