Introduction

1. High-Performance Industrial Control Computer
High performance Industrial control computer is adopted as the controlling computer, through which you can run the windows operating system directly. 6.4″TFT true color LCD display, tracking ball and optimized keyboard are allocated on the faceplate of this tester, which can be used without the external mouse and keyboard.
2. Digital Signal Processor Microcomputer
High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced.
3. D/A Conversion and Low-Pass Filtering
High precision D/A converter is employed for ensuring the precision and linearity of current and voltage in the whole range.
4. Voltage and Current Amplifier
For phase current and voltage, we persist in adopting high performance linear amplifier output mode in order to make the current and voltage source to directly output all kinds of waveforms from the DC waveform to the waveforms including all kinds of frequency components, such as square wave, combined waveform overlapped by each order harmonic, fault transient waveform, etc. In addition, the output waveform is clear and smooth without high-frequency radiated interference with neighboring equipments. It can simulate well all kinds of current and voltage characteristics under the circumstance of short circuit fault.
5. Digital Input and output
This tester has 10 channels digital input and 8 channels output.
6. Auxiliary DC Power Supply Output for Special Use
A circuit of special adjustable DC power supply output is allocated on the rear panel, which has 110V and 220V two shifts that can be used as test standby power supply on the spot.
