Quick fact

Devices for generating charging voltages (23 A) for all batteries installed in the motorcaravan (living area, starter, or auxiliary battery)
EBLs distribute and protect the output circuits
The overall supply switching is via two electronic main switches (MOSFETs)
The living area supply on / off switch and the vehicle supply on / off switch with complete isolation of all consumers from the batteries (shutdown)
Connection facility for auxiliary chargers (20 A)
Connection facility for solar charge controller (up to 20 A charging current)
D+ signal evaluation
3 electronic switched outputs (water pump, two additional switched outputs), function customer specicfic programmable, e.g. for fridge
Input for water tap contacts (microswitches)
Low quiescent current consumption
Integrated booster with 35 A
IUoU, integrated charging output with two adjustable slide switches for lithium 1 + 2, AGM, lead-gel
CI BUS Connector (Panel , Li-Batteries, 3rd party devices)
Tank probe connectors
Parallel panel interface

Product description

The EBL 557 Electroblocks is a motorcaravan power supply unit designed to generate charging voltages for all onboard batteries with integrated 23 A capacity. It distributes and protects circuits while managing power through electronic main switches for complete system control. Featuring connections for auxiliary and solar chargers, an integrated booster, and configurable outputs, it ensures efficient energy management. With low standby consumption and IUoU charging for multiple battery types, it provides reliable and flexible onboard performance.
