DC-DC converter Buck-Boost for smart alternators

Description

The Buck-Boost charges a 12 V or 24 V service battery in vehicles with a smart alternator (Euro 5 and Euro 6) with the right current. Such alternators do not always deliver the correct charge current; the converter compensates for this. A built-in engine running detection only lets it supply current once the engine has started, protecting the starter battery against deep discharge. The settings are programmed via PC software over USB.

Features

• Charges a 12 V or 24 V service battery with a smart alternator (Euro 5 and Euro 6)
• Input and output voltage range 10–30 V, undervoltage threshold 10 V
• Built-in engine running detection protects the starter battery against deep discharge
• Programmable via PC software over USB, voltage and current limits adjustable
• LED status indicators
• Versions with 25, 50 or 100 A charge current at 12 V
• Important accessory: CAN bus temperature sensor, especially for LFP lithium batteries

Application

For vehicles and boats with a smart alternator whose service battery – including an LFP lithium battery – is to be charged.

Selection guide

When charging LFP lithium batteries in cold conditions, the CAN bus temperature sensor accessory is important: it reduces the charge current below 5 °C and stops charging below 0 °C.
