The Wakespeed 48v/12v Bi-Directional DC-DC Converter simplifies and streamlines installation with its efficient Bi-Directional Buck-Boost DC-DC Converter. From installation using the existing chassis alternator to supplementing or even replacing the chassis alternator with a high-energy unit, the WS48-12x seamlessly manages power distribution, putting it exactly where you need it.
- WS500 Advanced Alternator Regulator is required.
- Seamless transfer of up to 3,000 watts of power from one voltage bus to the other.
- Support for 12v/48v power buses.
- Works with existing chassis alternators – no changes needed.
- Charge higher voltage batteries utilizing existing chassis electrical system.
- Suppliant system power generation using 2nd higher voltage alternator fully controlled by the WS3000.
- On demand supplemental chassis electrical system power to support surge loads without cost of additional batteries.
- J1939/RV-C based CAN support for system and BMS integration.
- Wide BMS integration support, both CAN and non-CAN based batteries.
- Compatible with additional WS500 controlled alternators installed in same system.
