Automatic Transfer Switch for 3 – 50 Amp Power Sources ES-350
Automatic Transfer Switch for 3 – 50 Amp Power Sources Automatic Switching between shorepower, generator, and inverter. Three heavy duty contactors designed for rigorous use, rated up to 50 amps 120/240V shoreline, 12 KW generator, and 6KW, 120V Inverter. Transfers both hot and neutral legs simultaneously. Designed to shed inverter power loads, when used with a 30 amp transfer switch. Utilizes both mechanical and electrical interlocks, to insure no power feedback. Built-in time delay allows generator to get up to speed. Quick and easy installation. Designed for OEM and aftermarket applications. The ES350 is designed to monitor both legs of the generator, with generator always being dominant supply source. Board also performs as time delay (average 37 sec.), with the added feature of switching the unit to shore power, after the time delay sequence, should generator power output drop to 105 volts or less for 5 seconds. If shore power is not available, unit will source inverter power. Once the generator output is over 105 volts, then the unit will switch from shore power or inverter back to generator. The ES350 is designed for use, not to exceed, generators having a rated output of 50 amps 120/240 VAC single phase 60Hz, external power source (shorepower cord) of 50 amps 120/240 VAC single phase 60Hz, and up to 50A 120VAC inverter.
