Intelligent Power Switch

Intelligent Power Switch

Intelligent power switch protects power lines. R5550K can detect two different over current thresholds and an under voltage error. When the R5550K detects over current, the switch turns off after the preset delay time. If an abnormal voltage is detected, the switch turns off after the preset delay time (10ms). After detecting the abnormal situation, the switch turns on again automatically if the cause of the error is removed.
