Three Phase Standard Meter With Power Source Combined

Description

Application:

This instrument is applied for high accuracy calibration, such as the measurement of various voltage、current、power and other parameter for utilities.  And It is also used for calibrating high accuracy signal source for utilities and companies.

Features:

1.     Output pure sine power signal with distortion degree 0.*3ï¼… (typical value).

2.     Duplicate each harmonic output on base wave

3.     Frequency output adjust within *0Hz～*5Hz, with differentiation 0.**2Hz and accuracy 0.**4Hz.

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～**0.

6.     Strong loading capacity. It can load with capacitive, reductive, resistive or combined load type, with the load adjust rate better than 0.*1ï¼…RG.

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

8.     *2 digits MCU+DSP CPU, powerful function.

9.     Weekly wave can reach ****0 point for industrial frequency.  It does not need filter for internal signal output and guarantee the accurate wave output.

*0.   8.4 inch big touch screen display.

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

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

*3.   Open communication protocol, easy for the second development.

*4.   Can be with pure capacitive load.

*5.   Calibrating energy meter with PC software.

*6.   Can output signal of 0～±*0V，0～*4mA to calibrate transducer.

*7.   Can measure voltage、 current、power、energy、harmonics and etc.

*8.   Can measure small DC signal.
