Charge Regulator SCR Marine

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 operating and provides useable power as soon as electric consumers are switched on. This state of charge is indicated by a LED.

The SCR Marine is suitable for lead acid batteries, gel batteries and AGM batteries (AGM = Absorbed Glass Mat) and has temperature compensated charging characteristics. For special applications, the maximum charging voltage can be adjusted to customer requirements.

The charge regulator SCR Marine is completely sealed and effectively protectet against the marine environment. It has two separate outputs, which can be used to charge two battery sets separately (eg. starter battery and service battery on a yacht).

Important: An advantage of the CRM is that it only regulates the voltage of the wind turbine. It is not influenced by (and does not influence) other power sources connected to the battery like alternators, gensets etc.

Stop-Switch

The stop switch is used to shut down the wind generator if it is not to be operated or to prevent starting of the rotor when working on it. Wiring the stop switch is not obligatory if a charge regulator has been installed.

When using the Superwind on a boat or a sailing yacht, the stop switch is strongly recommended to shut the wind turbine down in heavy weather at sea. Spray and waves, parts detached from the rigg or from the sails etc. could touch the rotor. Furthermore in such situations the restricted mobility on board increases the risk of accidentially touching the running rotor.

If the system is operated without charge regulator, a stop switch is necessary. In this case charging must be continuously supervised by the operator and terminated when the battery is fully charged. The stop switch disconnects the Superwind from the battery and simultaneously shuts down the rotor. The stop switch must be installed in the line between the wind generator and the battery as close to the wind generator as possible. In this line between wind generator and stop switch fuses or circuit breakers must not be installed.

The stop switch has two positions

RUN
The positive line from the generator is connected to the battery. The negattive line from the generator is connected to the battery.

STOP
The positive line and the negative line from the wind generator are short-circuited. (generator short circuit brakes the rotor) The positive and the negative lines from the battery are both open and disconnected from the wind generator.

The stop switch is designed for indoor panel mounting. For easy adaption to panels of up to 22 mm thickness, the shaft is adjustable.
