Active current limitation combined with thermal shutdown and automatic restart, protect the device against overload. In overload condition, channel turns off and back on automatically so as to maintain junction BLOCK DIAGRAM PowerSO-36 temperature between TTSD and TR. If this condition makes case temperature reach TCSD, overloaded channel is turned off and will restart only when case temperature has decreased down to TCR (see waveform 3 page 8). Non overloaded channels continue to operate normally. Device automatically turns off in case of ground pin disconnection. This device is especially suitable for industrial applications conform to IEC 1131 (Programmable Controllers International Standard).
