Votronic D+ Simulator Pro - 3067

The D+ Simulator Pro generates the control signal by detecting the vibrations of the running engine. It operates fully automatically and independently of the alternator's charging operation, making it particularly suitable for vehicles with alternator management, such as those compliant with the Euro 6 standard. With its low current consumption of less than 3mA, it meets the requirements of DIN EN 13976.

If additional consumers are only to be switched on when the engine is running (the alternator supplies power) or if the on-board battery is to be optimally charged via a charging converter while driving, the D+ contact of the alternator is usually used for control. However, this contact is often not accessible in the vehicle or is no longer available in newer alternators. This is where the VOTRONIC D+ Simulator comes in. It generates a voltage-controlled signal (e.g. from the starter battery) for a (isolating) relay or a charging converter. Further application possibilities arise in the control of additional consumers which are only to be activated when the battery is sufficiently charged, such as switching on an air conditioning system while driving or switching a refrigerator, a 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 energy-optimized alternator controls. This is where the new Votronic D+ Simulator PRO comes in. It operates independently of the alternator's charging mode, generating the signal by detecting the vibrations of the running engine.

This makes it suitable for all vehicle types of all models. To bridge start-stop phases (e.g., at traffic lights) or stop-and-go situations (e.g., in traffic jams), the new D+ Simulator Pro features an adjustable shutdown delay. Additionally, a built-in charging voltage monitor prevents accidental activation due to external vibrations, such as during ferry rides.
