STS Single Phase DIN Rail Split Keypad Electricity Meter
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
- Meter is durable and operable for harsh and severe environment
- Easy and quick to install
- Disconnect on preset credit level and tamper.
- Slim-line design to reduce operational cost
