BATTERY GUARD KEMO M148A 12V/DC

This battery saver protects your car battery from total discharge by switching off consumers such as ice boxes, heaters, radios + television sets, etc. in time. It switches on again automatically after return of the normal voltage. The interrupting voltage is adjustable: approx. 10.4 - 13.3 V.
 

The module is installed in such a manner that it is not exposed to humidity, strong vibrations or great heat. No additional cooling is required for load currents up to approx. 10 A. The module should, however, be installed “well ventilated” so that any heat that may possibly occur is carried off from the metal plate through circulation of air. In case of higher currents 10 - 20 A the module has to be mounted with a metal plate planely on another larger metal plate so that the heat will be carried off. We recommend a plate of approx. 10 x 15 x 0.5 cm or the like with a similar cooling effect. The base plate of the module must not heat up to more than 70°C during continuous operation. 
 

Depending on the load the module heats up. The heat is dissipated from the aluminum plate at the bottom of the module. Under certain circumstances it must be mounted on a cooling surface according to installation instructions. It is important that the module is fixed with 4 M3 screws (or 2.9 mm metal screws) on the cooling surface. This may be the back wall of a metal casing. The aluminum plate on the bottom of the module must not bend, do not use larger screws and do not drill larger holes. The screw heads must rest on the plate of the module, rather than on the plastic edge of the module! During assembly, the module should not be curled up (if the ground is not flat).
 

Important! The aluminium base plate must not be exposed to mechanical tension (do not drill holes, do not screw on an uneven cooling surface, etc.).
