Surge Protector with Voltage Protection, Hardwired 50-amp

Catalog Item # 56417

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. Features include: Built-in digital readout, built-in surge fault indication, amperage meter, voltage meter, frequency meter, integrated digital readout, 3-mode surge protection, and 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).

Modular design for easy repair, eliminating removal of the unit. Should the software ever change, EMS owners can receive a free upgrade at no cost.

You CANNOT use the remote display with the LCHW30 or LCHW50. These models have a built-in display and there is no provision for connecting an additional remote display. If you want a remote display, you'll have to purchase the HW30 or HW50 models which DO NOT have a display on the device. I prefer a display in the power compartment so I can see the power immediately after connecting. Having a remote display in the coach would be nice, but only if there were also one in the electrical compartment.

No, the EMS-RDS(SKU#56418) remote display is not compatible with the LCHW series surge protectors(SKU#56417 & 56406) as they have a built-in display.

The remote display is used with the EMS-HW30C(SKU#56419) and EMS-HW50C(SKU#56420).

Assuming a "dogbone" is a typical 50 to 30 amp adapter, the answer is yes. The unit will work properly with any 120 or 240 volt service applied and, it will check to make sure your adapters and the supplied power are wired and configured properly. If not, it will give you a fault code and prevent power from being applied to the RV. I've supplied power to my coach via this unit from 50 amp, 30 amp, standard 15/20 amp wall outlets, and offboard generators. It performs flawlessly.
