Product Description

Ningbo factory Single phase two wire ammeter energy electrical instrument

Product Overview

DDS149 type single-phase two-wire electronic energy meter with power-stealing prevention,Use the special large scale integrated circuits and SMT technology, using industrial grade international well-known brand longevity life components, accurate measurement of 50 ~ 60Hz AC power grid single-phase active energy,. Have good reliability and anti stealing electricity, broad negative load, low power consumption, high precision and strong anti-interference ability.

Function and features

1. Double circuit measuring positive and reverse active energy.

2. passive photoelectric isolation technology is used to output the passive power pulse signal, and the light emitting diode indicator is used to.

3. Have reverse indicate,Pressure lose indicate function.

4. Preventing electricity-stolen function:

1) RC power supply, resistance to electromagnetic power-stealing.

2) The current imbalance of power-stealing.

3) To prevent the reverse circuit power-stealing.

4) Can be measured in the case of neutral is missing
