CLOU Three Phase Electronic Meter CL730D25
CLOU Three Phase Electronic Meter CL730D25

The CL730D25 is a direct connected three-phase smart meter with an embeded RS485 solution for local access. The meter is used to measure electrical energy accurately for commercial, industrial and residential customers. The meter has excellent tamper detection features. With a hand held unit (HHU) various smart metering functions can be realized without extending the existing infrastructure. The communication with the meter is DLMS compliant.
