VOTRONIC - Innovative Elektronik Made in Germany

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

Often, however, this signal is not accessible in the vehicle or is no longer available with newer alternators. The VOTRONIC D+ simulator can help here. It generates a voltage-controlled (e.g. from the starter battery) a corresponding signal for a (cut-off) relay or a charging converter. Other possible uses are the control of additional consumers that should only be activated when the battery is sufficiently charged, e.g. switching on an air conditioning system while driving or switching a refrigerator, cold or warm box to 12 V on-board operation.

In newer vehicles (Euro 6), a voltage-controlled simulation of the D+ signal is often no longer possible due to the energy-optimized alternator controls. This is where the new VOTRONIC D+ Simulator PRO comes into play.

It works independently of the alternator's charging mode, as it generates the signal by recognizing the vibrations of the running engine. Thus it is suitable for all vehicle types of all years of construction. In order to bridge start-stop phases (e.g. at traffic lights) or stop-and-go (e.g. in a traffic jam), the new D+ Simulator Pro has an adjustable switch-off delay. In addition, a built-in charging voltage monitor prevents unwanted activation in the event of external vibrations, such as for ferry trips.

D+Simulator PRO

The VOTRONIC D+ simulator Pro generates the control signal by recognizing the vibrations of the running engine. It works fully automatically and independently of the charging operation of the alternator and is therefore particularly suitable for vehicles that have an alternator management, this can be e.g. vehicles that comply with the Euro 6 standard. With its low power consumption of less than 3mA, it meets the requirements of DIN EN 13976.

• Switching output: max. 0.3 A (+ switching, overload and short-circuit proof)
• Switch-on delay approx. 4 seconds to avoid incorrect activation
• Adjustable, additional voltage monitoring and switch-off delay
• Display of the device status via three-color LED
• Low own consumption
• Suitable for 12 V and 24 V systems.

D+Simulator

An intelligent voltage evaluation of the switching thresholds avoids control errors in case of voltage drops or peaks. The dynamic threshold recognition avoids swinging around the switching points when switching very large loads. The display of the switching state is effected by a light-emitting diode. The electronic system is protected against humidity; the connection is made in the rear terminal box by means of a plug-in type terminal screw. The rating of the terminal is 12 V / 0.5 A, it is short circuit-proof and overload-proof and of the type PNP, plus output, load ground side.
