AVS3P Automatic Voltage Switchers

The AVP3P is an Automatic Voltage Switcher designed to protect three phase loads from voltage fluctuations, over voltage, under voltage, surges, dips, and frequent starts/stops. The output is a single-volt-free changeover contact, rated at 16A. This is intended to control an external contactor, control circuit, start/stop system, or alarm. If the voltage on any one phase goes above or below the pre-set limits(the 'window'), then the AVP3P will switch off. Once the voltage returns within the window limits, the AVP3P will wait for a pre-set time, continuing to check the voltages, before automatically turning the load back on. The over-voltage, under-voltage, and delay settings are all adjustable using controls in the terminal compartment of the AVP3P. The standard window that is considered acceptable is 185V-260V(320V-450V three phase). Outside these limits electronic and electrical equipment are likely to be damaged.
