BATTERY ISOLATOR RELAY COLE HERSE INSTALL

For example, the 48051 with a rating of 75A has a per leg rating of 37.5A per leg. All Littelfuse–Cole Hersee brand battery isolators have a per leg rating equal to half the alternator rating. A 4-stud battery isolator can be used with older pattern alternators (in this case the 4th stud will remain unconnected), but a 3-stud battery isolator cannot be used with the Delcotron-type alternator.īattery isolators have a ‘per leg’ rating which indicates the maximum current it can deliver to either battery. The newer alternators were first introduced by Delco and are therefore sometimes called ‘Delcotron-type alternators’. The small 4th stud is for connection to a circuit switched by the ignition switch. Most alternators on new vehicles have an integral electronic voltage regulator that requires the use of the 4-stud battery isolator. The amp rating of each item is the maximum alternator rating. In addition, both batteries can be charged simultaneously from one source. KKK-A-1822B.įor vehicles with two batteries, these devices electrically isolate the batteries to prevent the battery with the higher charge from draining into that with the lower charge.

Reduces the load on the charging system by not connecting the auxiliary battery until the primary battery is charged to 13.2V which extends the life of charging components.The Cole Hersee Diode Battery Isolator 48051-BX is used to isolate medical equipment batteries from vehicle batteries. 48070 Battery Isolator Guard Max 70A Alternator 12-36V DC Cole Hersee Co No.

Allows bi-directional charging from the alternator or from shore power.

There are no efficiency losses due to diodes.

Smaller and lighter than traditional isolators.

This heavy duty 50 A switch allows forward and reverse motion of a motor without the need for a relay, especially for operation of tarps on trucks. The Cole Hersee range features models which can be used for more common applications.
