Model YEM181QP three phase four wire electromechanical multi-rate front board

installed active energy meter is a kind of new style three phase four wire active

energy meter, it is designed on the basis of original DEM082 meter, which gathers

functions of multi-rate (time-sharing billing) electric energy measuring and max

demand electric measuring. The meter completely accords with relevant technical

requirements of class 2 three phase active energy meter stipulated in international

standard IEC 62053-11. It can accurately and directly measure 50Hz or 60Hz active

energy consumption from three phase four wire AC electricity net, it is used for

setting indoor or out door meter box.

1. Front board three fixed installation, the bottom of the meter and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. The cover is also made of bakelite material and has a transparent glass window.It has following features: good weatherability, high rigid, good insulation performance, etc.
2. It has four tariffs, 6 time area, 12 date time.
3. Infrared remote-control programmable, password recognition.
4. It can keep the data forever when the power cut off, there is maintenance-free reserve battery in it.
5. Function ofmax demand electric measuring
6. May select port of RS485 and output pulse passive, it is useful copying meter conveniently.
7. Standard configuration bottom bearing is used of double gem bearing, oriented bearing is made of high wear resistance copper alloy bush and stainless steel needle. It has following features: long life and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is QD).
8. Standard configuration 6 digits display by drum wheel mechanical register, may select 5 digits display by drum wheel mechanical register (Product Configuration code is QV).
9. Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
10. Three component measure three phase four wire active energy consumption. Complying with standard IEC 62053-11.
11. Standard configuration direct connect operation, type 16B wiring, may select use CT for operation, type 48B wiring (Product Configuration code is QQ) and PT & CT for operation, type 48B wiring (Product Configuration code is QR).
12. Extension terminals cover, in order to protect to use safety.
