Single Phase Din Rail Split Type Prepaid Electricity Meter
a STE18-D operates with a 35 mm Din Rail mounting and pole mounting accessories, consists of two parts. A customer interface unit (CIU), and a metering and control unit (MCU). A CIU is a keypad based display to be installed within consumers homes wherever there is a plug point. MCU is the main meter, installed away from consumer’s home in a kiosk, meter box and pole-mounted enclosure.
MCU communicates with CIU via wireless communication such as Power Line Carrier (PLC), Radio Frequency (RF), LORA or 2-wires. This non-wired setup allows for easy inspection by utility and service providers at any time without visiting consumers’ houses and reduces the chance of fraud by tampering.
