Product Details

The SDM630 MCT V2 Three Phase Multifunction Energy Meter measures single and three phase supplies, while displaying all the fundamental electrical parameters. The unit is either 1A or 5A current transformer operated and be powered using a separate auxiliary (AC or DC). With a cost-effective price, this meter is best suited for sub-billing and energy management.
