3. 2. 13. Power Supply Unit - NT 44

Function:

The NT 44 power supply unit supplies high constant voltage (e.g. at lambda probes and other loads). An active 4-wire circuit ensures that line resistances up to 1 ohm and the related voltage drops are compensated.
The polarity of the heating voltage is reversed automatically at regular intervals to avoid effects of oxidation on the lambda probe heating which shorten the life of the probe.
