Votronic D+ Simulator Pro - 3067

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 conforming to the Euro 6 standard. With its low current consumption of less than 3mA, it meets the requirements of DIN EN 13976.

If auxiliary consumers are only to be switched on when the engine is running (the alternator is supplying power) or if the leisure battery is to be optimally charged by a charge 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 no longer exists in newer alternators. The VOTRONIC D+ Simulator provides a remedy here. It generates a corresponding signal for a (cut-off) relay or a charge converter, controlled by voltage (e.g., from the starter battery). Further applications arise in controlling auxiliary consumers that should only be activated when the battery is sufficiently charged, such as switching on an air conditioner while driving or switching a refrigerator, a cold or warm box to 12 V on-board operation.

In newer vehicles (Euro 6), 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 into play. It operates independently of the alternator's charging operation, as it generates the signal by detecting the vibrations of the running engine.

This makes it suitable for all vehicle types of all model years. To bridge start-stop phases (e.g., at traffic lights) or stop-and-go (e.g., in traffic jams), the new D+ Simulator Pro has an adjustable switch-off delay. In addition, a built-in charging voltage monitor prevents unintentional activation due to external vibrations, such as during ferry journeys.
