Product Description

 Intelligent Energy Monitoring Unit:-

1] IEMU is Intelligent Energy Monitoring Unit. It consists of an Energy Meter & a communication device. CT (Current Transformer), PT (Potential Transformer), GPRS signal (Telecom Network) should be available on site for installing the device. The connection is similar to connecting a meter on the site.

2] The metering unit performs 3-phase/Single phase metering with a default accuracy of Class 1(with an option of Class 0.5/0.2)

  3] The communication unit performs the function of obtaining the power consumption parameters from the metering unit to either a concentrator (ZigBee protocol) or straight to the Internet through a GPRS module 

 Metering Unit Specification:-

Accuracy: Class 1 (Default) IEC 61036, IS 13779 CBIP 88 Class 0.5 and 0.2s  (Optional available at extra cost).

Sensing/Measurement: True RMS, 1 Sec update time, 4 Quadrant Power & Energy

Input voltage: 4 Voltage inputs (VR, VY, VB, VN); Programmable 110 or 415 V LL Nominal(Range 80 - 550 V LL), Primary Programmable up to 999 kV, Burden: 0.2 VA Max. Per phase.

Input current: Current inputs (AR, AY, AB) 50 mA – 6 A (Field programmable 1A or 5A), Primary Programmable up to 99 kA, Overload: 10A max continuous, 50A max for 3 sec, Burden: 0.2 VA Max. Per phase.

Aux-Supply: (Control Power) 80 – 300 V AC, (DC Optional), 40-70 Hz, Burden: 4 VA Max

 Display Type:  10 mm height; Bright red LED display
