IP54 Single Phase Electric Meter 35mm Din Rail Keypad Prepaid Meter
Micro Grid 35mm Din Rail Keypad Prepaid Meter with RF Communication Remotely Monitoring
The CA168-S is designed as split type, MCU(Main Control Unit) and UIU(User Interface Unit), connected by RF communication. It is suitable for Mini Grid (Micro Grid/Off Grid) solar PV generatation, can be used in 5A, 16A, 40A, 60A current. The meter build in prepayment algorithm which compliance with the STS (Standard Transfer Specification) protocol, the meter will shut off the power automatically when the credit is used up even though there is no any communication between meter and system.
Due to the in-built RF communication in the MCU, the AMR management system can be developed for you to monitoring the meter consumption, collect data from the meter (Credits, consumption, events, etc) and remotely control. The DCU(Data Concentrator Unit) collect the data from the nearby meters by RF, and then upload the data to the system by GPRS.
Major Features
20 digit (Standard Transfer Specification) STS encryption
Up to 80A current with Class 1 accuracy
Disconnects on overload and no credit
Programmable power limit and low credit warning
Adjustable power limit trip
Enhanced tamper detection for magnetic field, reverse connection, cover open, etc.
Reverse energy measurement SRE
Information toggled by codes
Tamper trip protection : neutral missing
Other Benefits
a) Compact and slim-line design
b) PLC/ RF communication for MCU & UIU and same with back end AMI server (On request)
c) Time of Use (TOU) , multi-rate, tariff control, holiday setting
d) 15 year designed life
e) Enhanced revenue protection through flexible payment control
