KD330 microcomputer relay protection tester

Main Features
Intelligent host, controlled by DSP chip and 16 bit DAC output, can generate high-density sine waves of 2000 points per week for the base wave, which is the highest level among domestic testers. Greatly improved waveform quality and enhanced the accuracy of the testing instrument.
Single machine independent operation, the device is operated by a rotating mouse through a large LCD screen, with a complete set of Chinese display. It can calibrate various relays, protections, and automatic devices on site, and simulate various large and complex instantaneous, * *, and conversion faults for whole group testing.
By connecting to a computer and using the complete set of Chinese operating software on the Windows 98 platform, various large-scale, complex, and highly automated calibration tasks can be performed. It is convenient to test and scan various protection settings, store test data in real time, display vector diagrams, draw fault waveforms, and print reports online.
The LCD display adopts a 320 × 240 dot matrix graphics module, and the operation interface is displayed in Chinese, which is intuitive and clear.
The "foolproof" operation uses a "rotating mouse" controller with *, eliminating complex keyboard operations and allowing for easy and easy learning without the need for computer knowledge.
The whole machine adopts switch power supply and switch amplifier technology, with small size and light weight, weighing only 11.6 kilograms.
Modular design, all plugins are independent of each other, and hardware maintenance and upgrades can be achieved by simply replacing the plugins.
Random configuration, such as configuring as 6-phase current, 5-phase voltage+2-phase current, etc.
Users can calibrate the accuracy of the tester through software
Can replay fault waveform data in Comtrade format.
According to the standard design, there is a power factor correction circuit for the power supply, which enables the device efficiency to reach over 95%.
When the power supply voltage drops to 120V, the device still operates normally.
The amplifier adopts hardware protection to ensure the reliability of the device.
