Blue Star’s C500 watt-hour meter meets the IEC 61036 (class 1.0S) 
standard for energy meters. The main features of C500 include none 
physical adjustment components, digital signal processing, digital filters, 
digital error correction, digital calibration, immunity to temperature 
fluctuation, and excellent stability. Due to its 12 times overload multiplier, 
A0 can record energy usage of extreme low load. It can precisely 
measure the voltage, current and power. 
  
The basic function of C500 is single-phase active import and export 
energy metering.  
  
Infrared communication protocol complies with IEC1107.  
 
C500 Meter data processing functions include: 

1.  Energy measurement via digital measuring chips in order to digitally 

verify the metering precision. 

2.  Active import and export energy metering through data provided by 

electrical energy measuring chips. 

3.  Export energy is added to import energy, and export Energy metering 

in independent register. Single rate energy for metering of active import 
and export energy.  

4. Energy metering ranges from 0 – 9999999.9 kWh or 0 – 

999999.99kWh. 

5.  One channel  pulse output test: active energy verifying pulse ， the 

breadth is 80ms. 

6.  Pulse indication for energy metering through one LEDs of high 

brightness indicating active energy on the left.  

 

Data of energy mentioned above can be displayed on LCD. LCD is 
“multiplex screen of graphic matrix with paragraph style”. Data are 
displayed with matrix English letters. 

 

Passive pulse output interface with optical-coupling insulation.
