... The LED string is protected against over voltage by the over OVP voltage divider for each channel. The OVP threshold is adjusted to approx. 60V on the 1st channel ( Low- and High-Beam) and approx. 50V on the 2nd channel (Daytime Running Light). That means, an output voltage of > 60V at the 1st chann ...

Voltage optimisation

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.
