ISO 9001 Factory YEM021DF Three Phase Four Wire Electronic Energy Meter,Din Rail Active Counter Energy Meter/

Model YEM021DF 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 accords with relevant technical requirements of

class 1 three phase active energy meter stipulated in international standard IEC 62053-21.

It can accurately and directly measure 50Hz or 60Hz active energy consumption from three

phase four wire AC electricity net. It can display total energy consumption by step motor

type impulse register. 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.

• Standard configuration 6 digits display (999999kWh) by step motor type impulse register.

• There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant, the output rate is 10 or 100 imp/kWh (can select). And contact with all kind of AMR system conveniently.

• Five LED instructions respectively every power supply state and signal of closed energy impulse and distant energy impulse.

• Automatic detection the direction of the flow of load current. And instructions (signal of closed energy impulse is green when working,that is measuring the direction of the flow of load current reverse).

• 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.

• May select two components measure three phase three wire active energy (Product Configuration code is DE) or two phase three wire active energy (Product Configuration code is DD).

• Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation, we can also choose another type of wiring, and use 5+1 digits display by impulse register.

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