... Current Limitation (minimum values) Current limitation is realized by increasing the resistance of the device which leads to rapid temperature rise inside. A temperature sensor for each channel causes an over- heated channel to switch off to prevent destruction. After cooling down with thermal hysteresis, the channel switches on again. Please refer to IN ...
