AP1:6. Thermal protection sensors
The thermal protection sensors are placed inside the power modules (or module)
and on the heatsink of the output rectifier. In the power module there are (is) NTC
(negative temperature coefficient) non--linear sensor -- 22kΩ @ 25_C, while on the
output rectifier the PTC (positive temperature coefficient) 1,0 kΩ @ 25_C linear
sensor is installed.
The replacement of the sensor in the heatsink can be carried out only along with
damaging the old sensor. The new one should be installed by means of the
electrically non--conductive and thermally conductive silicon rubber.
