Mastervolt BI 1202-S

BI 1202-S

Onboard systems usually consist of two or more batteries that
function independently when powering the 12, 24 or 48 V consumers.
These batteries require independent charging with reliable battery
isolators or battery combiners.

Mastervolt offers several intelligent solutions:

Features:

• Battery isolators that divide your charge current with a
  minimum energy loss.
• The Charge Mate for connecting and/or disconnecting two
  batteries.
• Battery Watch for monitoring the condition of your batteries
  (also usable as main switch).

 

Mastervolt’s BI battery isolators are based on conventional
diode technology. The diode voltage drop (ca. 0.6 V) can be
compensated for by adapting the output voltage of the connected
charger or alternator. Mastervolt battery chargers and Alpha Pro MB
charge regulators come as standard with automatic voltage drop
compensation.

Compact and lightweight

The Mastervolt BI battery isolators are compact and fully solid
state, preventing wear. The weight varies from 580 to 1300
grams.

Robust and durable

Completely corrosion-proof material with aluminium heat
sinks. The electronic components are encased in synthetic
materials, the BI models have molded diode splitters.

Fast installation

The synthetic end plates feature connection lugs, the solid bolt
connections with nuts and locking rings ensure easy
installation.
