In a resounding departure from the vast majority of multi-stage 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 – to create a smarter approach to battery care. Highly configurable and enabled to communicate via J1939 CAN protocol, the WS500 provides superior charging efficiency, and the singular ability to address the specific needs of newer battery technologies like LiFePO4 and similar chemistries.Ideal for RV or marine applications, the WS500 auto-adjusts for 12-, 24- and 48-volt systems and allows advanced user-configuration for system voltages in between. The WS500 can be easily configured to most popular battery types: standard and high-density AGM, standard and deep-cycle flooded, gel, carbon foam and TPPL via an internal switch. Two custom presets (one of which is preconfigured for a LiFeP04 battery profile) can be configured to battery manufacturer recommendations or by an OEM installer to deliver optimized charging for specific applications. Advanced configuration via PC provides adjustment to more than 100 charging modes.Some other exclusive features of the WS500 include:• Adaptive Idle Technology™ minimizes impact of the alternator on smaller engines by controlling alternator loads based on engine rpm.• Zero Output Technology™ enables the regulator to limit output to loads when batteries require discontinued charging.• Multiple Alternator Support, without need for relays or switching devices.• Full BMS Compatibility using RV-C and OSEnergy protocols
Select your Wiring harness based on whether you need positive or negative type alternator excitation. You WILL need either a Positive or Negative Wiring Harness unless you are prepared to build your own. Make sure you include it when you buy. For a quick overview of the differences and how to check your alternator, scroll down to the “How to determine Alternator polarity” link.
You may also wish to include a battery temperature sensor wiring harness. This is optional but is strongly recommended, especially in “Battery Centric” configurations where the WS500 can reduce its output when your battery starts to warm up.
