The KDJB1200 microcomputer relay protection calibrator adopts a structure that operates independently as a single machine or can also be connected to a laptop for operation. The host is equipped with a new generation high-speed digital signal processor microcomputer, a true 16 bit DAC module, a new modular high fidelity high-power amplifier, a large screen LCD display, and a flexible and convenient rotating mouse controller. Single machine independent operation already has strong functionality and can perform most experiments, while connecting to a computer for operation has stronger operational capabilities.

1. The classic Windows XP operating interface is user-friendly and easy to operate. In order to facilitate user use, a large number of keyboard shortcuts have been defined, making the operation "one click in place";
2. High performance embedded industrial control computers and 8.4-inch high-resolution color TFT LCD screens can provide rich and intuitive information, including the current working status of the equipment, next step work prompts, and various help information;
3. Equipped with an industrial keyboard and optical mouse, various operations can be completed through the keyboard or mouse just like operating a regular PC;
4. Equipped with an external USB interface for convenient data access and software maintenance;
5. Testing of the project can be completed without the need for external devices, automatically displaying and recording test data, and completing the depiction of vector diagrams and characteristic curves;
6. By using a high-performance D/A converter, the waveform generated has high accuracy, good linearity, and excellent transient response and amplitude frequency characteristics. Ensure waveform accuracy and other indicators within the measurement range;
7. The algorithm used produces accurate waveforms, which is different from the waveform generation method of curve fitting, ensuring that the signal is a pure sine wave;
8. Can directly output AC voltage, AC current, DC voltage, DC current, with variable amplitude, phase, frequency, and 2nd to 20th harmonics;
9. The power amplification part adopts a new high-power high fidelity linear power amplifier circuit, which has high output power and low ripple interference. Each phase voltage can output 120V and current can output 30A. When the output current reaches 30A, the waveform can still ensure no distortion or peak shaving;
10. It has 16 input ports and 8 pairs of output ports with open contacts. The input interface can automatically adapt to passive (air contact) and active inputs, and can automatically adapt to the polarity of active inputs. It can work normally within the input voltage range of ± 250V;
