Micro Grid 35mm Din Rail Keypad Prepaid Electricity Meter

with RF Communication Remotely Monitoring for minigrid offgrid rural

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

1. 20 digit (Standard Transfer Specification) STS encryption
2. Up to 80A current with Class 1 accuracy
3. Disconnects on overload and no credit
4. Programmable power limit and low credit warning
5. Adjustable power limit trip
6. Enhanced tamper detection for magnetic field, reverse connection, cover open, etc.
