INSTALLATION & SERVICE MANUAL

TM

50 AMP Smart Energy Management System  Model 900

PRODUCT DESCRIPTION

 

TM

The 

50 Amp Smart EMS  Model 900

 consists of two elements: the 

Display Panel

 and the 

Distribution Panel.   

The 

Display Panel is mounted on a wall or suitable surface, remotely from the distribution panel and convenient to the user.  
The Distribution Panel is a completely self-contained 120/240 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.

TM 

Circuit Breakers

 - the 

50 Amp Smart EMS

 

Model 900

 Distribution Panel offers slots for eight single or dual, standard 

120 volt circuit breakers.   Two of these breakers, located in the two center stab positions, must be  50 Amp units that act as 
a main input protection for each of the lines supplying the remainder of the branch breakers (up to 12).

TM

 

Energy Management

 - the 

50 Amp Smart EMS Model 900

 automatically senses the available power to the vehicle.   It 

determines whether it is connected to a 120 VAC - 30 Amp shore power source, 240 VAC - 50 Amp shore power source, or 
Generator source.   Depending upon available power, it controls the operation of 6 possible loads that may include: the 
front and rear air conditioner fan, and compressor using low voltage switching, and other 120 Volt loads (such as the 
refrigerator, water heater, washer/dryer, or other large appliances).  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.

HOW IT WORKS

TM

The 

50 AMP SMART EMS

 

Model 900

 provides main circuit protection for 120/240 VAC split phase incoming lines and 

branch circuit protection for up to 12 circuits, including Energy Management of up to six selected branch circuits.  If 120 
VAC - 30/20 Amp source is available, the control helps to limit the total current draw of all the appliances in the RV at or 
below 30/20 Amps provided by the main power feed.  If the Generator source is available, the   control helps to limit the 
total current draw of all the appliances in the RV at or below the rated current provided by the Generator, which is 45 Amps 
for gas-powered generators or 60 Amps for diesel-powered generators (installer selectable).    

Circuit Protection:

Circuit protection for ALL the 120 VAC loads is offered by standard, reset-able circuit breakers, provided by the installer.  
There are eight positions available for circuit breakers.   The breakers located in the two center stab positions must be 50 
Amp breakers to act as the main breakers for the entire system.   These breakers back-feed power into the circuit breaker 
bus to feed power to the branch breakers.The remaining six positions may be occupied by single, or dual units.  All the 
loads in the RV are fed from the branch breakers.

Energy Management:

Note 

- When connected to 50 Amp - 240 VAC Service the Energy Management features of the unit are disabled and the 

unit switches all controlled loads"ON".

The main neutral line is routed through the magnetically coupled current sensor, which measures the current flowing 
through the neutral line.     This is the total amount being drawn by all the 120 volt appliances in the RV when the available 
power service is 120 VAC.  When this current exceeds the "shore" service rating of 30 Amps (20 Amps if the threshold has 

TM

been set lower) or the generator service rating and 240 VAC service is not available, the 

50 AMP SMART EMS  

will turn 

off the controlled loads in an effort to bring the total current to the limit of the incoming service.

Controlled Loads:

The system offers control of up to six powered loads; each one connected to one of the relay circuits of the 

50 AMP Smart 

TM

EMS  Model 900

 system.   Four of these relays: relays 1, 2, 3, and 4, are 30 Amp relays with normally-open contacts used 

to interrupt the 120 volt power to the loads.   These circuits are intended to control 120 volt appliances such as refrigerator, 
water heater, washer/dryer, coffee maker, etc.  

For the 120 VAC switched loads, power is routed from the individual branch circuit breakers to one of these 120 VAC 
relays on the Control Module.   The controlled load is then fed from that relay.
