Harmonic Source Electrical Measuring Instruments High Accuracy With Capacitive Load

High Accuracy Harmonic Source electrical testing and measurement instruments

Features

1. Can output pure sinusoidal power signal (representative value of distortion: 0.03％)
2. Can overlap harmonics on base wave
3. Frequency adjustable during 40Hz～65Hz,resolution 0.002Hz, accuracy 0.002Hz
4. AB Phase with a frequency reference and C phase an independent frequency reference
5. Phase can be regulated from 0 to 360, convenient to simulate the states of power supply, even the situation of reverse feeding.
6. Can be with capacitive load, inductive load, resistive load or mixed load, load regulation rate better than 0.01%RG.
7. excellent temperature stability (coefficient less than 1PPM) will ensure the accuracy of testing out of doors
8. Powerful with 32 bit MCU+DSP processor
9. high precision harmonic output and low distortion
10. With RS232 communication interface for connection with PC
11. Perfect over-current, over-voltage, short circuit, open circuit, over-load protection
12. Adopts hardware PID, fast response, changing of load will not influence the output
13. 320*240 LCD display and operation is easy
14. open communication protocol to facilitate the secondary development ( factory automatic verification of RTU/FTU/Power management terminal/common transformer terminal)
15. Can be with pure capacitive load
16. can calibrate energy meter matching with PC software
