CT / 5A 3 Phase Active Din Rail Energy Meter With Pulse Output  & Liquid Crystal Display 

Product Description

Din rail energy meter YEM021AC is three phase four wire active electronic DIN rail active energy meter. The meter adopts up to date micro-electronics technique and imported special large sacle intergreated circuit and SMT technology. The meter are completely conformed to the relative requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurately measure 50Hz / 60Hz active energy consumption from three phase four wire AC electricity net and display the data by seven digits LCD. The main characteristic of the meter is that it can be connected with CT. User can set 27 ratios according to his need, and the meter can directly reading the data without mutiplying the CT rate, making it more conveniently to read the data. 

Specification

* If you need different reference voltage or current specification, please advisory our sales personnel.

Competitive Advantage

1. It can choose many kinds of installation way, such as 35mm standard DIN rail installation, or front board installed (mounting holes center distance 63 mm), users can choose any one by themselves.

2. Type S wiring (Inlet from bottom, outlet from top), use CT connect operation, may select set 27 ratio, after set the meter will direct reading when read, and haven’t multiplied by rate of CT.

3. Seven digits display LCD, 5+2 digits display (99999.91 kWh, only ratio of CT when 5:5 A) or 7digits, it is choose by ratio of CT which is set.

4. There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant (the output rate is 10 kWh/pulse), ). Complying with standard IEC 62053-31 and DIN 43864.

5. Standard configuration there are a port of far infrared data communication and a port of RS485 data communication. Communication agreement complying with standard DL/T645-1997, can also choose without function of data communication. (Product Configuration code is NC).

6. Six LED instructions respectively every power supply state, signal of closed energy impulse and distant energy impulse and data communication state.

7. Automatic detection the direction of the flow of load current. And Instructions on individual LCD

8. Within 18 months from the date of manufacture, if the meter still being sealed does not conform to any technical requirements of IEC62053-21, the manufacturer guarantees to repair freely or to change.
