WhisperPower Battery Link WBL 120
120 A smart battery link that connects two battery banks for shared charging when charge voltage rises and isolates them when voltage drops; for 12 V and 24 V systems.
Description
The WhisperPower Battery Link WBL 120 is a smart switching regulator that automatically connects two battery banks when the charge voltage stays above a threshold, so both are charged from one source, and separates them again when the voltage drops.
Key features
- Simultaneous charging of two battery banks from one source
- Safe-connect algorithm and intelligent battery monitoring
- Start-assist function: banks can be connected in parallel for emergency starting
- Automatic isolation on voltage drop
- No programming required; compact and robust
- Optional remote control; LED indicators
Technical data
- Part number: 60110120
- Continuous capacity: 120 A; peak/inrush (10 s): 180 A
- Input voltage: 9–35 VDC
