Three-phase electronic inactive watt-hour meter

Detailed Product Description

product brief introduction The three-phase electronic inactive electronic energy meter is the new-generation reactive electric energy metering device researched and developed based on special measure chips, this product is mainly used for measuring three-phase reactive electronic energy in AC electrical network whose rated frequency is 50Hz,it can directly substitute for inductive type three-phase reactive electric energy meter. With infrared interface or RS485 interface, the communication rule of this product conforms to GB/T645-1997,it owns many advantages as low power consumptionhigh precisionhigh sensitivitystrong overload abilitywell electromagnetic compatibilitylong endurance and anti electric larceny etc.Its main technical index conforms to GB/T17882-1999.  function and features 1. Accurately measure three-phase reactive electric energy Three-phase power supply feeding, even if three are one phase (three-phase three-wire)or two phase(three-phase four-wire) power off, the power supply also can supply power normally.2. wholly electronic type design ,metering is accurate,sine90°really reactive metering3. Adopting SMTtechnique and choosing international renowned brand elements with long endurance, so its reliability is high.4..high precisionhigh sensitivitylow power consumption and wide load .5.Volt transformer feeding, wide work volt range.6. passive photo-electricity isolated impulse output  specification and technical data 1.
