SMART ENGERGY MANAGEMENT SYSTEM
Intellitec
131 Eisenhower Lane North

630.268.0010/1.800.251.2408
The System senses when the coach is connected to a 50 Amp service, or operating
from the generator and allows simultaneous operation of all the 120 volt loads. When
50 Amp service is not available and the coach is connected to a smaller electrical
service, such as 30 or 20 Amp, the system automatically takes control of the loads to
practically eliminate circuit breaker tripping. It constantly monitors the total amount of
current drawn in the RV and controls the loads, as necessary, to keep the total current
to a value less than, or equal to, the available power service.
There is no programming necessary and the unit will work with any load within the
circuit breaker limits. The Smart EMS automatically "learns" the amount of current
drawn by each of the controlled loads as it turns them on and off. In this way, it auto-
matically adapts to differing loads, or loads whose current changes with line voltage
or temperature.
Smart EMS Operation
The Airstream A-Series motorhomes are equipped with 50 Amp electrical service and
over-load is typically not a problem. However, 50 Amp service is often not available
at campsites. It is then that energy management system is needed. The Smart EMS
controls certain electrical loads to limit the peak demand, thereby almost eliminating
nuisance circuit breaker tripping.
Large appliances, such as air conditioners, water heater, washer/dryer, coffee maker,
etc., whose use can be can be temporarily postponed, are automatically controlled.
ELECTRICAL SYSTEM
Temporarily postponing their use leaves enough power to operate the "on demand"
appliances, such as the microwave, hair dryer, or toaster.
Smart EMS turns off each controlled appliance when the total current in the RV ex-
ceeds 30 amps. It will restore appliance power when the total current drops below a
level connected to 20, or 30 Amp service that allows it to operate again.
EMS REMOTE MONITOR PANEL
The optional remote monitor panel is located in the galley area and displays a digital
readout of the total amount of current being drawn by all the loads in the coach. A
series of LED's indicate the loads that have power applied. When the power is avail-
able, the LED will be on. The panel includes a switch to select operation from 30 Amp
or 20 Amp service.
