3×127/220 3×230/400 Active Three Phase Electronic Energy Meter With Four Wire
Product Description:
Model YEM321DT three phase four wire electronic front board installed active energy meter is a kind of new style three phase four wire active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net, it is use for setting indoor or out door, it can display total energy consumption by step motor type impulse register. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

Competitive Advantage
1. Front board three fixed installation, up and down mounting holes center distance is 198-212 mm, users can choose any one by themselves.
2. 6 digits display (999999KWh) by step motor type impulse register.
3. Standard configuration only a polarity port of pulse output passive , may select add a nonpolarity port of pulse output passive distant (Product Configuration code is DI). And contact with all kind of AMR system conveniently,Complying with standard IEC 62053-31 and DIN 43864.
4. Four LED instructions respectively power supply state and signal of energy impulse.
5. Measure the active energy consumption in one direction on three phase four wire, which is not related with the load current flow direction at all, complying with Standards IEC 62053-21
6. Standard configuration direct connect operation , type 16B wiring, we can also choose another type of wiring, and use 5+1 digits display by impulse register, CT (Product Configuration code is DV) and PT & CT (Product Configuration code is DX) for operation, it is type 48B wiring.
7. LEDs indicate separately the power state, the energy impulse signal, load current flow direction, current tariff state and data communication state.
8. The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation, or extension terminal cover for safety.
9. All of our products have proceeded aging test,and products have the guarantee period of 24 calendar months.
10. 3. We are a sales team, with all technical support from engineer team.
