48V/12V Bi-Directional DC-DC Converter

Description

Unlock next-level power capabilities with high-energy systems and experience lower costs, faster charging, and more real-world power availability!

The Wakespeed 48v/12v Bi-Directional DC-DC Converter (WS48-12x) 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.

Wakespeed Configuration Utility App:

*Hardware Updates (Including Configuration File Transfers) Require PC or Android based Phone.

*The lithium ion battery market has become immersed by a rapidly growing number of internally BMS controlled “drop in” batteries that provide little or no ability to communicate with other devices like the WS500 or other charge sources. In many cases, these drop in batteries use disconnects as a normal part of charge control. Unfortunately, these batteries make it impossible to anticipate disconnects because of the lack of suitable forewarning. Wakespeed has worked closely with the battery manufacturers represented in our list of pre-engineered configuration profiles to ensure that the regulator will have the ability to charge the listed batteries safely — as such, we recommend using batteries and BMS systems included in this list. Using the WS500 regulator with batteries that aren’t included in our list of pre-engineered charging profiles may result in unintended disconnects and potential load dumps and voltage spikes. If you choose to use batteries not listed below, beware that Wakespeed cannot guarantee the safety of your charging system. Wakespeed holds no responsibility for damage caused by use of the WS500 regulator when connected to a LiFePo4 battery system not included in the list below.
