electronic ac ammeter(LTCBW1)

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 metering
3. 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
