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 equipped with alternator management, such as vehicles meeting Euro 6 standards. With its low current consumption of less than 3 mA, it meets the requirements of DIN EN 13976.

If auxiliary consumers are only to be switched on when the engine is running (when the alternator is supplying power) or if the onboard battery is to be optimally charged during driving via a charge converter, the alternator's D+ contact is usually used for control. However, this contact is often inaccessible in the vehicle or no longer present on newer alternators. The VOTRONIC D+ Simulator solves this problem. It generates a corresponding signal for a (disconnecting) relay or charge converter, controlled by voltage (e.g. from the starter battery). Additional applications include controlling auxiliary consumers that are only to be activated when the battery has sufficient charge, such as switching on an air conditioner during driving or switching a refrigerator, cooling box, or heating box to 12 V onboard 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 because it generates the signal by detecting the vibrations of the running engine.

It is therefore suitable for all vehicle types of all model years. To bridge start-stop phases (e.g. at traffic lights) or stop-and-go traffic (e.g. in traffic jams), the new D+ Simulator Pro features an adjustable switch-off delay. In addition, a built-in charging voltage monitor prevents unwanted activation due to external vibrations, such as on ferry crossings.
