Voltage Regulator/Backup Power Supply
Environment When the Series 1000 is being used for the resale of fuel, Weights and Measures
regulations require a backup power supply. The voltage regulator/backup power
supply protects line-operated equipment from low line voltage (brownout) and
total line power failure by providing virtually instant emergency power. The
voltage regulator/backup power supply also protects line-operated equipment
from potentially dangerous voltage spikes coming in on the commercial AC
power. Although it does help to condition the power to the Series 1000, it cannot
totally compensate for extremely poor power conditions. The voltage
regulator/backup power supply must be located in an area protected from direct
contact with weather (typically near the system circuit breakers) and should be no
further than 50 feet from the Series 1000 System for optimum protection. The
unit is designed for an operating temperature range of 32
o F to 112 o F.
