Installation Instruction
Product Feature
The AKH-0.66/SM series provides two independent outputs from one current transformer. The first output supplies AC 0-5A or AC 0-1A for measuring and metering devices. The second output supplies DC 4-20mA for automation systems such as PLC or DCS, with the DC 24V auxiliary power supplied by the PLC. The series includes SM-50I, SM-60II, SM-80II, SM-100II, SM-120II and SM-200II models, covering primary currents from 5A to 6300A depending on the selected model and ratio.
