Model YEM421JC 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 accord 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.It has following features:

good reliability, small volume, light weight, specious nice appearance, convenient

installation, etc.

• 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.

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

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

• 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)

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

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

• 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.

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

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