The TriStar pulse width modulated (PWM) controller can operate as a solar charge controller, a load controller, or a diversion regulator in 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 UL current ratings of 45 and 60 amps. A choice of 7 different setpoints are easily selectable with DIP switches. An RS-232 communications enables PC connection to adjust control setpoints and data logging. 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 RJ-11 jacks. Battery temperature compensation may be added with the optional temperature sensor. Knocks-outs on the bottom of the charge controller match knock-out spacing on the Xantrex DC-175/250 disconnect and the OutBack FLEXware power system components, allowing easy mounting on either.
