WBL 140 (WhisperPower Battery Links) are smart switch regulators that automatically connect two battery banks if the charge voltage rises above a certain value for at least five seconds. This means that the battery banks can be charged from the same source. To protect the battery banks they are separated from each other as soon as the voltage drops.
- Simultaneous charging of two batteries
- Intelligent battery monitoring function
- Safe connect algorithm
- Temporary additional power with start assist function
- Simple to install, no programming required
- Compact and robust
- Automatic isolation with voltage drop
- Remote control possible (optional)
- Connect battery banks in parallel for emergency start
- LED indicators
