Compact voltage regulator for all alternators with 12Volt. The regulator supplies alternating current and optionally also direct current. It is therefore not only the perfect and reliable replacement for all conventional voltage regulators, it also enables a modern expansion of the existing on-board power supply system.


AC - AC alternating current: Input and output for the unregulated alternating current of the ignition base plate and the regulated current for the wiring harness.

  • SENSE: The AC input and output must be bridged. The output voltage is compared with a reference via the sense line (bridge). This way the voltage remains constant even if the load fluctuates.
  • DC Direct current: Output with direct current for charging the battery. However, if the ignition system is powerful enough, consumers can also be connected directly. For example: Satnav systems, water pumps, tachometers, speedometers and all other imaginable toys.
  • Earth - Ground: Ground connection to the frame, can be easily taken over from the old controller. Otherwise output ground to frame and best still to the housing of the controller.

The connection to the existing wiring harness is very simple. For complete AC systems, simply connect the regulated AC current to the cables for the electrical consumers. For systems that are operated with AC and DC, a distinction only needs to be made between AC and DC and the cables must be wired accordingly.
