• Reliability- Nations has the experience and quality to last under the harshest conditions

Wakespeed WS500 Advanced Regulator

In a resounding departure from the vast majority of multi-stage voltage-only regulators currently available, the WS500 uses a unique approach to charge control by factoring multiple criteria - battery voltage, current in, current out, battery temperature, alternator temperature - resulting in a smarter approach to battery and system care. Highly configurable and able to communicate via J1939 CAN protocol, the WS500 provides superior charging efficiency and safety along with the singular ability to address the specific needs of newer battery technologies like LiFePO4 and similar chemistries.

Ideal for RV applications, some exclusive features of the WS500 include:

• Active regulation of voltage, current, and temperatures to assure proper battery charging while protecting the system - including ensuring battery C rate is never exceeded without needing to artificially restrict the alternator capacity.

• Zero Output Technology allows alternators to continue to power house loads after the battery is fully changed.
• Adaptive Idle Technology reduces alternator load at lower engine RPMs to minimize impact on performance.
• Auto-adjusts for 12, 24, 48/51 volt systems and allows advanced user-configuration for system voltages in between.
• CAN communication for ease of install and reliable measurement of critical battery and system information such as: battery amperage/voltage, alternator and battery temperature, battery capacity and status, electrical and engine loads
• Full BMS and Operator Display compatibility using RV-C, OSEnergy and other protocols
