Description

Summary : DDS*-electronic single-phase power meter used advanced ultra-low-power solid-state integrated circuits technology and SMT and hot air reflow Process design and manufacture, applied metering frequency of *0 Hz AC Single-phase watt-hour. All of its properties are in line with all the technical requirements in the IEC***6 and GB/T*********2 standard 1.0 *- Single Phase. The precision basically can not be affected by frequency, temperature, voltage, high harmonics, and the location of installation is arbitrary. After a piece of product sale out from the factory, it did not need any adjustment, extended test cycle, thus significantly reducing the electricity sector testing and meter calibration, reliability than other similar products have improved markedly. The main functions and features : The product has high accuracy, high sensitivity, high reliability and wide load, low power consumption, small size, light weight, easy to install, automate management, to facilitate expansion of functional features. This product is a two-way measurable function can accurately measure the positive and negative direction of the two active power, in the same direction and accumulated power, and consequently, in various ways defense Filching functions (such as reverse pilfer, Filching burglary appliances, etc.). This table in electric meter-button boxes, set up bright pulse coupling interface and tagging (+),(-), can facilitate error testing.
