STS Single Phase DIN Rail Split Keypad Electricity Meter

Smart Split Keypad Prepaid Single Phase Electricity Meter is composed of a prepaid keypad single phase electricity meter and a separate customer interface unit(CIU) with RF, PLC wireless communication module or two wires.

Single Phase Din-rail Split-type Prepaid Electricity Meter

The CAD168 Meter is a split-type compact DIN-Rail mounted Class 1 accuracy single phase electricity meter built in 35mm international standard housing made of poly-carbonate flame retardant materials.Galvanic isolation wire is basic connection between the meter and keypad. Double circuit measurement and relay are also available on request for reinforced tamper prevention.

Main Features

  • 20 digit (Standard Transfer Specification) STS encryption
  • Slim-line and space-economy design,
  • Up to 13kV/6.5kA surge protection for lightening and other line surges
  • Up to 80A current with Class 1 accuracy
  • Disconnects on overload and no credit
  • Programmable power limit and low credit warning

 

Split Configuration for Increased Revenue Protection

The meter consists of two parts, the MCU (Metering & Control Unit) and UIU (User Interface Unit). The MCU and UIU is linked via galvanically-isolated 2-wire communication cable. Power line carrier (PLC) and Radio Frequency (RF) communication module is also available on request.The UIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.

 

User benefit

  1. Meter is durable and operable for harsh and severe environment 
  1. Easy and quick to install 
  2. Disconnect on preset credit level and tamper.
  3. Slim-line design to reduce operational cost
