Product Details

Purpose:
DT(X)The S825 electronic three-phase active and reactive combined energy meter has high accuracy and reliability. This product adopts internationally advanced ultra-low power large-scale integrated circuit technology and SMT process, and key components are selected from international brands. Long life devices improve the reliability and service life of products. It can accurately measure active and reactive energy in a three-phase power grid with a rated frequency of 50Hz, and can replace two ordinary three-phase energy meters. Reactive power measurement adopts a 90 degree phase-shift measurement method, with inductive and capacitive reactive power meters. A wheel type meter is used to measure active and reactive energy, which is intuitive and easy to read and use. The product complies with all technical requirements for electronic three-phase energy meters in GB/T17215-2002 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T17882-1999 "Level 2 and Level 3 Static AC Reactive Energy Meters" standards.

Functional features:,
⊙ Bidirectional power measurement and counting, anti-theft, high precision, high reliability, high overload, low power consumption, and light weight.
⊙ Measuring three-phase active energy, no need for inspection during long-term operation.
⊙ Three phase power supply, with one wire (any one of the three wires in a three-phase three wire energy meter) or two wires (any two of the four wires in a three-phase four wire energy meter) disconnected, the accuracy of measurement is not affected.
⊙ Wide working temperature range.
⊙ Equipped with electrical energy testing signal output.
⊙ Dual meter display, displaying reactive and active power respectively (LCD displays reactive and active power, and stores data).

Technical parameters:

Starting current:

Active power ≤ 0.002Ib (connected via transformer),

Reactive power ≤ 0.003Ib (connected through a transformer),

Active power ≤ 0.004Ib (direct access),

Reactive power ≤ 0.005Ib (direct connection),

Subtle movement:

Add 115% Un to the voltage circuit, and when the current loop current is 0, the output pulse of the energy meter should not exceed one.
