VOLTAGE REGULATION
Voltage regulation description:
Automatic Voltage Regulation (AVR) circuits maintain clean, regulated computer-grade 120V
nominal output, without using battery power, during brownouts to 75V and overvoltages to
147V
Overvoltage correction:
Input voltages between 128 and 147V AC are reduced by 12%
Direct pass through:
Input voltages between 108 and 127V AC are passed on to connected equipment
unchanged
Brownout correction:
Input voltages between 93 and 107V AC are boosted by 14%
Severe brownout correction:
Input voltages between 75 and 92V AC are boosted by 30%
LEDS ALARMS & SWITCHES
Front panel LEDs:
4 front-panel indicator LEDs show line power status, battery power status, battery
low/replace status and voltage regulation operation
Alarms:
Audible alarm indicates power failure conditions, silenceable via alarm cancel switch. Once
cancelled, alarm will resume when approximately 2 minutes of battery operation remain
