CT&PT LCD DISPLAY THREE PHASE DIN RAIL ACTIVE AND REACTIVE ENERGY METER WITH BUILT-IN LITHIUM BATTERY

Product Description

Model YEM421MC three phase four wire electronic DIN rail active and reactive integration energy meter is a kind of new style three phase four wire active energy meter, it adopts micro-electronics technique, and imported large scale integrate circuit, uses advanced technique of digital and SMT techniques, etc. The meter completely accords with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21 and class 2 three phase reactive energy meter stipulated in international standard IEC 62053-23. It can accurately and directly measure 50Hz or 60Hz active and reactive energy consumption from three phase four wire AC electricity net, it can display total energy consumption by step motor type impulse register. This meter has seven digits LCD displays shows active energy.And there is a maintenance-free lithium battery in it, use for displaying power cut reading. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

Functions

1. 35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board installed (mounting holes center distance 63 mm), users can choose any one by themselves.

2. Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.

3. 7 digits LCD display, 6+1 digits(999999. 1kWh),may select 5+2 digits display. (Please specified when ordering)

4. There is a maintenance-free lithium battery in it, use for displaying power cut reading.

5. Standard configuration one port of active pulse output passive and one port of reactive pulse output passive(polarity),The output rate are 0.01, 0.1, 1, 10kWh or kvarh/Pulse.Users can choose any one by themselves. May select one port of active pulse output passive and one port of reactive pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently,Complying with standard IEC 62053-31 and DIN 43864. (Please specified when ordering)

6.Five LED instructions every power supply state and signal of active energy impulse and reactive energy impulse.

7. Automatic detection the direction of the flow of load current. And instructions by one LED.

8.Single direction three components measure three phase four wire active and reactive energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21and IEC 62053-23.

9.Standard configuration type S wiring (Inlet from top, outlet from bottom), directly connect operation, may select use CT (Product Configuration code is LC) and PT&CT (Product Configuration code is KC) for operation.

10. Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is MF).
