    Equipped with a powerful 60 Hz 1800 RPM General Motors engine, the Gillette SP-520 Series 50/52kW Gas Standby Generator is the right solution for all critical power needs. This fully digital generator set comes with a Deep Sea 7420 microprocessor controller that auto starts the system during a power failure. The controller also monitors speed, voltage, pressure and fuel levels as well as offering configurable inputs and outputs, timers and modes while making it easy to see data through the LCD display. 

    The Gillette SP-520 Series 50/52kW Gas Standby Generator runs on 50,000 watts on natural gas and 52,000 watts on liquid propane gas. It also features a heavy-duty 100% to 125% rated circuit breaker as well as an automatic voltage regulator with over-excitation, under-frequency compensation, under-speed protection and EMI filtering. Five different voltage options ensure that commercial establishments get enough power for their needs.

It measures 78”L x 42”W x 38”H for the open unit and 94”L x 42”W x 53”H for the enclosed unit. This series has a fuel consumption of 750 cu. ft/hr. on natural gas and 8.10 gal/hr. on LP gas.
