PRODUCT DESCRIPTION

The

is a completely self-contained120 volt power distribution and energy management system

intended to be used in recreational vehicles. It is housed in a sheet metal enclosure with removable front panel. It
provides circuit protection for all the 120 VAC loads in the RV and a system of energy management to minimize the
over-loading and tripping of circuit breakers.

- the

offers slots for four single or dual, standard 120 volt circuit breakers. One of

these breakers must be a 30 Amp unit that acts as a main input protection for the remainder of the branch breakers
(up to 7).

- the

offers control of up to four, 120 volt operated appliances to help keep the

total 120 volt current draw to less than 30 Amps. These appliances may be any type load, but are typically heavier
loads, those whose use can be "postponed" until a time when current is available for their use.
