Whenever electrical power falls below 104 volts or rises above 132 volts, the EMS automatically shuts down power to the RV.
Once the electrical power 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 the RV. Remote digital readout features built-in surge fault indication, amperage meter, voltage meter, frequency meter, 3-mode surge protection, reverse polarity protection, open neutral/open ground protection, lost/open neutral protection, and AC frequency protection. Factory setting 15 seconds but can be adjusted to a 2 minute 16 seconds (136 seconds) delay for A/C Protection. Frequency Protection (Low <51Hz, High 69HZ>).
Remote display: Scrolls continuously through all of the power source information: voltage, current, frequency, error codes, and previous errors. Each reading is displayed for 2 seconds. Modular design for easy repair, eliminating removal of unit. Should the software ever change, EMS owners can receive a free upgrade at no cost.
The remote display works on 56419 (EMS-HW30C) and 56420 (EMS-HW50C).
Progressive Industries' Hardwired Electrical Management System (EMS) provides full RV surge and electrical protection against all adverse power conditions.
