Battery Control Booster MT BCB

Battery Control Booster MT BCB 20/20 IUoU

The new MT BCB 20/20 Battery Control Booster from BÜTTNER ELEKTRONIK is the ultimate 3-in-1 solution for charging your on-board batteries. Adjustable to battery type (gel, AGM, liquid), the batteries are always optimally charged according to the latest IUoU characteristics:

A charging current of 20 A is available on the 230 V network.

While driving, the alternator also provides 20A thanks to the booster function. For longer journeys, a full charge is guaranteed by the IUoU characteristic, which is adapted to the respective battery type. Overloads are therefore ruled out.

The device has a long-term charge programme and can remain constantly connected with the 230 V mains network. An integrated "pulser" prevents dangerous sulfation of the battery.

Naturally the device comes equipped with an inverter (gel, AGM, liquid acid) and a battery temperature sensor. The control panel can be removed and installed as a remote control in the interior.

All devices of the MT BCB 20/20 series are equipped with a high-voltage relay with cable set and fuse. This means it is very simple to install, even in vehicles which already have a built-in Electroblock (EBL).

Supplied with temperature sensor and connecting cable (5 m) for the control panel (cable extension No. 21212-15, optionally available), cable set, 12V 80A high-load relay, and fuse

Charging current in 12 V booster mode: 20 A
Dimensions (HxWxD): 223 x 70 x 270 mm

Battery Control Booster MT BCB 30/30/20 IUoU & MT BCB 40/40/30 IUoU

BCB 30/30 and BCB 40/40 are also optimal 3-in-1 solutions. Due to high output power, they are not only suitable for parallel charging of existing charging devices but can also be used as a main charging station. For self-assembly or van mounting, the 30A or 40A BCB version can be integrated directly between the start battery and vehicle battery. Lay the charging cable from the starter battery to the BCB and then to the on-board battery, the usual isolating relay is eliminated. Adjustable to wet; gel; AGM and common LiFePO4 battery systems.

Delivery incl. temp. sensor; cable extension (5m) for control panel.
If the BCB is installed in a vehicle with EBL, a high-voltage relay must be ordered as well.(Product No.: 259740)
