Overview

The S3 (T) - HW.S3-WHWHWH-N3-WHW active power/active energy combination transmitter is an instrument that can simultaneously measure the active power and active energy of a system. It only requires one set of input signals to convert the active power of the system into a DC signal and the active energy into a high linear ratio pulse output. When the active power is output in current mode, a common ground current output is used, which is more convenient for wiring with the secondary system and is a transmitter with high performance price ratio.

active power/Active energy transmitter

Overview

S3(T)-WHW. S3-WHWH. N3-WHWType active power/Active energy combinationA transmitter is an instrument that can simultaneously measure the active power and active electrical energy of a system. It only requires one set of input signals to convert the active power of the system into a DC signal and the active electrical energy into a high linear ratio pulse output. When the active power is output in current mode, a common ground current output is used, which is more convenient for wiring with the secondary system. It is a transmitter with high performance price ratio. It is suitable for frequencies of50Hzor60HzAnd special frequency three-phase three wire (balanced or unbalanced) systems, as well as electric energy measurement used for automated monitoring in non electric energy billing systems, andThe technical indicators of S3 (T) and N3 series active energy comply with the relevant provisions of GB/T15283-99 "0.5, 1, and 2 level AC active energy meters" standard regarding 0.5 level active energy meters.

feature

This series of products has high measurement accuracy, good conversion performance, good temperature characteristics, and lightning protection function. The ability to measure reverse active energyIt has long-distance transmission capability (4~20mA, 500 Ω), fixed in accordance with DIN46277, and can be installed on 35mm aluminum rails.
