Detailed Description

Star DDS26D Electronic Single Phase Watt-hour Meter is a brand-new and high-tech product, which adopts one special large-scale IC, the latest micro-electronic technologies and SMT techniques. It also takes more allowable ambient errors for circuit design and components selection so that the long-term operation stability can be guaranteed. Star DDS26 series of Electronic Single Phase Watt-hour Meter have the features of long life, high accuracy, high reliability, high allowable overload, little power consumption, small size & light weight etc The Function of Multi-tariff and Interval Energy Measurement. It can be programmed up to 24 intervals as well as 4-8 tariffs and measure the active energy separately. The tariff table, backup rate table and automatic conversion time for backup rate table can also be programmed and set at the customer’ disposal, Anti-tampering Function With the advanced anti-tampering technology, the energy meter can measure normally under the condition of tampering action by unbalanced current between neutral line and phase line, meanwhile it will indication for tampering and current reversing. Avoiding reversal or interchange of phase line and neutral line effectively. Events Recording Recording, reading power failure and programming events of the latest 50 times.. Communication Function With infrared communication and RS-485 communication function, the setting or cancel of the displaying contents, clock setting, intervals programming and data-collection can be achieved. The Function of Automatic Data Transfer Transfer the data of last month automatically on the date and hour settled for automatic transfer. The data can be reserved for 100 years after power failure. The Maximum Demand(MD) Measurement and Resetting Function The Function of Backlight and Power Failure Display The Function of Temperature detecting and Hardware Self-detecting Daylight saving switching function (optional) With selectable functions: Reversal, Cover-opening detection and Tampering Events recording. According to the customer’s needs, the reversal, cover-opening detection and tampering function is programmable. Reactive energy measuring Function (optional)
