The Progressive EMS-PT50C Portable RV Surge Protector provides high & low voltage protection, whenever source power falls below 104 Volts, or rises above 132 volts and will automatically shut down power to the RV. Once the AC source rises above 104-volts, or below the 132-volt level the time delay indicator flashes for the preset time and then automatically restores power to RV.
