Votronic D+ Simulator 12 V

If additional consumers are to be switched on only when the engine is running (the alternator supplies current) or if the on-board battery is to be optimally charged via a charging converter while driving, then the D+ contact of the alternator is usually used for control.

Often, however, this contact is not accessible in the vehicle or, in the case of newer alternators, is no longer available. This is where the VOTRONIC D+ Simulator comes in. It generates a voltage-controlled signal (e.g. from the starter battery) for a (cut-off) relay or a charging converter

Other possible applications include the control of additional consumers that should only be activated when the battery is sufficiently charged, such as switching on an air conditioning system while the vehicle is in motion or switching a refrigerator, cooling or heating box to 12 V on-board operation.

An intelligent voltage evaluation of the switching thresholds avoids false triggering in case of voltage dips or peaks. The dynamic threshold detection also avoids oscillation around the switching points when switching very large loads

The switching status is indicated by a light emitting diode. The connection is made in the rear terminal compartment by a plug-in screw terminal. The switching output is loadable with 12V / 0,5A, short-circuit and overload proof and of type PNP, plus output, load ground side.

The marine version are special devices with moisture-protected electronics additionally equipped
