PWM Control

The output is active from terminal 15 with a permanent clocking in a frequency of 100 Hz. In this way the power output is controlled. From a voltage of 12.8 V the pulse width modulation is adjusted in such a way as to provide a power output of 100% as for 12.8 V.

In the case of voltage drops in the vehicle electrical system of up to 1 V, the pulse width modulation is corrected and thus a constant brightness of the lamps connected at the consumer shutdown output is ensured.

Below 12.8 V voltage regulation is no longer corrected. The brightness can fluctuate with the battery voltage level.
