On-board power supply system

The EBL 252 electroblock consists of:

F

a charge module (18A) for charging all batteries connected

F

the complete 12V distribution system

F

fuses for the 12V circuits

An IT ... or LT ... control and display panel must be connected to the EBL 252 for operation.

Together these devices control the electrical functions in the vehicle’s leisure area, including

accessories.
It is also possible to connect an auxiliary charger (LAS ...) and solar regulator (LR ...).
Flat vehicle fuses and resettable fuses (Polyswitch) protect the various circuits.
The electroblock is protected from:

F

Overtemperature of the final charge stage

F

Overload of the various outputs

F

Short-circuit of the various outputs
