Protection
Over Voltage
Range(OUR)
When the measured value exceeds “Voltage Range × CF”
Over Current
Range(OCR)
When the measured value exceeds “Current Range × CF”
Over Current
Protection (OCP)
OCP will occur when the following measured current conditions are
exceeded.
1. 1.1Arms for low shunt range
2. 23Arms or 80Apeak for high shunt range
3. Burnt out of the 25A fast acting fuse (the current measurement
loop will become open circuit)
