The TriStar pulse width modulated (PWM) controller can operate as a solar charge controller, a load controller, or a diversion regulator in any 12, 24 or 48 volt systems. It can operate in only one of these modes at a time, but two or more controllers can be used to provide multiple functions. PWM operation may be changed to on/off operation to prevent telecom noise.
Two models are available with current ratings of 45 and 60 Amps. A choice of 7 different set points are easily selectable with DIP switches. An RS-232 communications device enables PC connection to adjust control set points and data logging.
Knock-outs on the bottom of the charge controller match knock-out spacing on MPPT controllers, allowing easy mounting to available power system components.
5-year warranty. UL Listed for U.S. and Canada.
An optional digital display may be mounted on the front of the controller or up to 100 feet away using 4-conductor phone cable with RJ11 jacks. Battery temperature compensation may be added with the optional temperature sensor.
