Superwind Wind Generators

Charge Regulator SCR Marine

The Superwind 350 is a small wind generator for professional use, which

The SCR Marine is designed to sense and limit the output voltage of a Superwind 350 12 V wind generator and thus to prevent batteries becoming overcharged.

It is suitable for lead acid batteries, gel batteries and AGM batteries (AGM = Absorbed Glass Mat) and has two battery charging outputs isolated by Schottky blocking diodes. This allows the wind turbine to charge two batteries totally independent of each other.

The SCR Marine is not influenced by other power sources connected to the batteries like alternators, gensets, solar arrays and battery chargers. For that reason, it can be used very well in complex systems and hybrid systems.

The regulator is fully potted to protect the electronics against humidity and vibration. Fields of application for example are sailing yachts, campers, summer cottages, mountain shelters, as well as industrial applications, like navigational aids, traffic management systems, environmental monitoring stations or transmitters.

The SCR Marine charge regulator has been especially designed for the Superwind 350 wind generator and guarantees optimum charging of the batteries. The secondary function of the SCR Marine is to electronically keep the wind generator under load. When the batteries have reached their maximum charging voltage, the SCR Marine's PWM circuit automatically diverts the wind turbine's surplus power to the dump resistors. Thus with batteries even fully charged, the wind turbine continues operation and provides usable power as soon as electric consumers are switched on. This state of charge is indicated by the LED and the resistors will make a very slight buzzing sound when operating and dissipating power.
