DLMS/COSEM Single Phase Din Rail Prepaid Energy Meter
The meter is a split-type compact Din Rail mounted class 1 accuracy single phase electricity meter built in 35mm international standard housing made of poly-carbonate flame retardant materials. Galvanic isolation wire is basic connection between the meter and keypad. Double circuit measurement and relay are also available on request for reinforced tamper prevention.
Split Configuration for Increased Revenue Protection
The CIU (Customer Interface Unit) is optional. The MCU (Metering & Control Unit) and UIU is linked via Mbus 2 wires communication, galvanically-isolated Power line carrier (PLC) or Radio Frequency (RF) wireless communication, the communication method is on request.
The UIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
