JOY211MP Split Single Phase Prepaid Electricity Meter
DESCRIPTION
JOY211MP Split Single Phase Prepaid Electricity Meter provides split solution for kWh measurement and
prepayment. Credit and management data is transferred from a point of sales (POS) to the meter via a 20-
digit numeric token that is generated using the Standard Transfer Specification (STS) encryption protocol
and entered into meter via a keypad.
The meter consists of two parts which is called MCU (Metering Control Unit) and CIU (Customer Interface
Unit). The MCU can be installed outside house and communicates with the CIU installed inside house via
Power Line Carrier (PLC) communication without any additional wires.
FEATURES
» STS compliant
» Keypad with audible and text feedback
» Enlarged LCD
» Adjustable audio and visual low credit warning levels
» Automatic diagnosis of various faults include contactor
fault, memory devices fault, etc.
» Improved sealing against ingress of insects
» IP54 Rated
» Significant Reverse Energy (SRE) detection
» Advanced tamper detection
» Easy switch between prepayment and post-payment option
