Many thanks for purchasing a superwind product. The SCR 12 Marine is a charge regulator of highest quality and will perfectly and reliably charge your batteries for many years. However, reliable operation not only will depend on product quality but also on accurate assembling and proper wiring. Please read this manual carefully before you start the installation. Please also keep in mind our safety instructions and warning notices. Our main concern is with your safety. Labelling This manual refers to the charge regulator SCR 12 Marine Manufacturer: superwind GmbH Am Rankewerk 2 4 D-50321 Brּhl / Germany Tel.: +49 / 2232 / 577357 Fax.: +49 / 2232 / 577368 e-Mail: [email protected] Internet: www.superwind.com You will find the label with the serial number and the nominal voltage on the side of the housing. Intended use and range of application The SCR 12 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 12 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. General safety recommendations Always abide by the acknowledged rules of technology and the rules for accident prevention when working on the electrical system. Take care that works on the electrical system like installation, maintenance and repair is carried out by qualified persons only. These persons must also have studied the instructions before given in this manual. 1 >

Batteries store a large amount of energy. In any circumstance avoid to short circuit a battery. For your safety connect a fuse to each of the battery cables. Charging lead-acid batteries produces inflammable hydrogen gas. Unsealed lead-acid batteries have vent holes releasing hydrogen, which forms detonating gas with the ambient air. A small spark e.g. of an electrical switch can detonate the explosive gas mixture. For explosion prevention therefore always provide sufficient ventilation. Avoid touching and short circuiting wires or terminals. Be aware that the voltage on specific terminals or...

Choosing the position The charge regulator and the dump resistors are designed for indoor use and shall be mounted at a place well protected from the effects of weather. As the charge regulator has a temperature sensor in order to adapt the charging voltage to the battery temperature, it should be placed in the same room with the batteries or in a room with the same temperature level. If this is not possible, an external temperature sensor is available (part no.: 0300.15.01.04) which then replaces the standard sensor mounted at the regulator housing. The distance between the regulator and the...

If you are not sure of the polarity of the cables led down from the wind generator you can identify POSITIVE (+) and NEGATIVE (-) easily by means of a simple multimeter before connecting the cables to the charge regulator. Select DC (range e.g. 10 VDC) on your multimeter, There is normally a red measuring line connected to the V plug and black line to the COM plug. Connect the measuring lines to the cables coming from the wind turbine. Ask an assistant to turn the rotor of the wind turbine slowly by hand. The wind turbine already produces low voltage gaugeable by the multimeter. If the voltage...

Connecting an additional solar panel The SCR 12 Marine can also be used for charge regulation of an additional solar panel ( See diagram below). The solar panels peak power output must not exceed 150 Watts. In order to prevent current flowing from the wind turbine to the solar panel, an extra blocking diode (Schottky diode) must be wired into the positive line of the solar panel. The blocking diodeԴs current rating must match with the solar panels maximum output. A ready-to-install blocking diode ( max. current 15 A / max. voltage 45 V ) can be ordered with superwind GmbH ( part no.: 0300.16.00.00)...
