Split Din Rail Mounted Kwh Meter UV Stable Polycarnonate Closure Cable Connection
The DDSY168-S is a splity Din Rail mounting designed prepayment meter . It is in an international 35mm Din Rail housing and keypad based with STS encryption.The meter is provided for a broad rang of prepayment applications,
The meter works in a dynamic broad range enabling a basic current of 5 Amp while keeping a maximum current of 80 Amp and expanded functional features.DDSY168 -S operates with a user interface unit as UIU, or in some countries, as customer interface unit (CIU). UIU or CIU is a keypad based display to be installed within consumers premise when the main meter, as, Metering and Control Unit, or MCU is installed out of the consumers' premises. This split design featuer provides utility users and service providers great convenience as well as value and enhanced revenue protection by inspecting and maintenancing meters without entering consumers' homes.
We as meter manufacturers, not only provide 35mm DIN RAIL,BS mounting , but also one of our most popular meter types. Both types connect to a CIU with a galvanically isolated communication cable and non-wired configuration as PLC, RF, MBUS are also available on request. Cable connection right now is the most reliable and stable communication however no-wired configuration adds more convenience and value to future operations.
Major Features
a) MCU UIU are separated for better tamper protection
b) Split connection is easy and low cost for deployment
c) Programmable power limit
d) Enhanced tamper detection for magnetic field, reverse connection, cover open, etc.
e) Significant reverse energy detection SRE
f) Information register display toggled by codes
User Benefits
a) Increasesd revenue protection through flexible payment control
b) PLC/ RF communication bw two parts and with back end server for AMI (On request)
c) Time of Use (TOU) , multi-rate, tariff control, holiday setting
d) Compact and slim design, space saving
e) Long life time design (15yrs)
