Progressive Industries’ Hardwired Electrical Management System (EMS) provides full RV surge and electrical protection against all adverse power conditions.
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).
