35mm Din Rail Electric Meter Power Line Carrier Prepayment Electricity Meter
The new generation DDSY168-S PLC meter is a compact, single-phase, keypad based, 60Amp (80 Amp optional) split prepayment meter in a Din Rail standard housing. Communication between the meter and the customer interface unit is by means of Power Line Carrier technology. (PLC) compliant.
The meter consists of two parts, the meter (MCU) and the customer interface unit(CIU). Communication between the meter and the customer interface unit is by means of Power Line Communication (PLC), using existing household wiring; - no additional communication wires are required.
The customer interface unit is a compact unit with a user-friendly keypad and display. It may be installed in any convenient location in the consumer’s home where there is an electrical socket outlet. The prepayment meter contains all critical metering, number decryption and load control functionality. It operates independently and is immune to any form of tampering on the customer interface unit.
The meter is usually installed in a secure, locked enclosure, typically a pavement kiosk or pole-mounted equivalent. It is outside the consumer’s home to facilitate easy inspection by the utility at any time and to reduce the opportunity of fraud by tampering.
Major Features

b) Optical port for alternative communication
c) Quick and easy to install - uses existing household wiring
d) Tamper detection, neutral missing
e) Significant Reverse Energy (SRE) detection
f) Programmable power limit
g) Prepayment or credit metering modes of operation
h) STS Compliant
i) Language independent user interface
j) Diagnostic LED’s on the meter
k) Backlighting on customer interface display, audible and visual low credit alarm,
l) High surge withstand capability for areas prone to lightning or other line surges
User Benefits
1) Ideal for retrofitting or replacement of conventional meters in apartment blocks and housing estates
2) Compact and slim-line design makes installation quick and low cost
3) IEC 62056-21 compliant optical allows utility to access information stored inside the meter
4) Allows landlords, complex manager or utility to input charge, tariff, debt collection settings
5) The meter can be switched between prepayment and credit mode
6) Two way communication for remote access
