APPLICATION:

The instrument is used for the calibration of high accuracy signal source in power system. And it is mainly applied in utilities、Measurement Bureaus、Quality Control System、Science & Technology Unit、and Manufacturers for energy meter、terminals、load control、power quality analysis、reactive compensation and etc.

MAIN FEATURES:

1、Output pure sine power signal with distortion degree 0.03％ (typical value).

2、Duplicate each harmonic output on base wave.

3、Frequency output adjust within 40Hz～65Hz, with differentiation 0.002Hz and accuracy 0.002Hz.

4、Phase AB is a frequency standard while phase C is an independent frequency standard, so frequency can be set according to different phases.

5、Phase position can be adjusted within 0～360.

6、Strong loading capacity. It can load with capacitive, reductive, resistive or combined load type, with the load adjust rate better than 0.01％RG.

7、Perfect temperature stability, with the temperature coefficient of core part is below 1PPM.

8、32 digits MCU+DSP CPU, powerful function

9、Weekly wave can reach 50000 point for industrial frequency.  It does not need filter for internal signal output and guarantee the accurate wave output.

10、Connection to PC via RS 232 port.

11、Perfect protection for over current、over voltage、over heat、short circuit、open circuit、and over load.

12、Hardware PID, no delay for output, fast response. The output will not be affected by the load change

13、320*240 LCD Display.

14、Open communication protocol

15、Can be with pure capacitive load

16、Calibrating energy meter with PC software
