This product is a new addition to the Enlight brand, please speak to our Sales team for further information.
The product is also available with WIRED communication between the meter and CIU. The same CIU’s as used in conjunction with the single phase product range.
The meter has a split configuration, which allows for increased revenue protection by mounting the Metering Control Unit (MCU) in a secure pavement kiosk or pole mounted box away from consumer access.
The standard BS mounting of the MCU means it is ideal to replace old electromechanical credit meters. The meter consists of two parts, the MCU and the Customer Interface Unit (CIU).
The PLC communication uses existing household wiring and does not require additional wiring to the consumer’s house.
The CIU can be conveniently located by plugging it into an available mains socket.
The meter is a 4 wire three phase meter and can operate as a simple prepayment or post payment meter, but is also ready for integration into a larger revenue protection system by providing the necessary open standards, interfaces and management features.
The meter has advanced features such as bi-directional metering, load profile and anti-tamper cover open detect and magnetic tamper detect.
METERING CONTROL UNIT (MCU)
The MCU consists of the metrology circuit, the STS decryption engine, load switch control and communications interfaces. A LCD display provides visual indication of remaining credit and total consumption while contactor, communication status and consumption rate are provided by LEDs. An IEC62055-52 compliant optical port is also standard. This port is used for data extraction and can also provide an interface to the revenue protection system.
The meter can be fitted with a wired port to allow a wired CIU to be connected to the meter as an alternative.
A version of the Split Three Phase is also available with a keypad on the MCU, allowing the technician easy access to the registers on the MCU through the short codes. (See image below).
The PLC communication is based on a highly robust implementation of the multi carrier OFDM technology. The phase, on which the PLC communications to the CIU is injected, can be selected during installation.
The MCU includes cover open (with and without power) and magnetic tamper detect and the meter cover makes provision for fitting utility anti tamper seals.
CUSTOMER INTERFACE UNIT (CIU)
The PLC stand-alone CIU can be plugged into an available mains socket.
The CIU is paired to an individual MCU during the installation process, ensuring privacy of data for the user.
The CIU includes a large LCD with user friendly language independent icons to display meter information in a user friendly format.
