It monitors the floating equipment ground voltage. If the voltage exceeds 40 V peak, | It monitors the floating equipment ground voltage. If the voltage exceeds 40 V peak, or ground current exceeds a selectable limit of 0.5, 3.5 or 5 mA, the A6901 disconnects mains power and grounds the test equipment. | ||
