Model YEM021JC three phase four wire electronic DIN rail active 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. It can accuratelyl and directly

measure 50Hz or 60Hz active energy consumption from three phase four wire AC

electricity net. This meter has seven digits LCD displays shows the active energy

consumption. 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.
• Seven digits display LCD, standard configuration 6+1 digits display (999999.1kWh). May select 5+2 digits display (Please specified when ordering).
• Standard configuration one port of pulse output passive(polarity),May select a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently,Complying with standard IEC 62053-31 and DIN 43864.
• Four LED instructions respectively every power supply state and signal of energy impulse.
• Automatic detection the direction of the flow of load current. And Instructions on individual LED.
• Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
• Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation,we can also choose another type of wiring, and useCT (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).
