Surge Safe Din Rail Kwh Meter Single Phase , Anti Tamper STS Prepaid Meters

The DDSY168-S is a compact, two wire, keypad-based prepayment electricity meter which comprises two parts, the Metering Control Unit ( MCU), or main meter,  and the Customer Interface Unit (CIU).

Consumer interaction with the meter and access to meter information (such as a low credit warning, energy consumption, and load contactor status) are available using the keypad and LCD display on the CIU. The CIU is the customer’s only interface with the meter, and is a compact unit with a user-friendly keypad and display. It is usually installed in a convenient location in the consumer’s home - remote from the MCU, and is connected to the MCU with a pair of communications wires.

The MCU contains all critical metering, number decryption and load control functionality. It operates independently and is immune to any form of tampering on the CIU interface. The MCU 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. As an option, the MCU can be supplied with its own LCD display and keypad, which allows the utility to view important meter parameters without the need for an interrogation tool.

The DDSY168-S is built with surge arrestor that is capable of sustaining up to 16kV line surges and lightening and also available with options for SMPS that allows the mete to operate under extrem low voltage down to 60V or even below.
