LDJB-1600 microcomputer relay protection tester

1、High-performance embedded industrial control computer and 10.4 "large-screen high-resolution color TFT LCD display, which can provide rich and intuitive information, including the current working status of the equipment, next step prompts and various help information, etc.;

2、The output terminal adopts high-fidelity, high-reliability modular linear power amplifier instead of switching power amplifier, with excellent performance. It will not produce high- and intermediate-frequency interference to the test site, and it ensures that the waveform is smooth and accurate in the whole process from large current to small current.

3、The output part is controlled by DSP, with fast calculation speed, strong real-time digital signal processing ability, wide transmission frequency, and high-resolution D/A conversion control. The output waveform has high precision, low distortion and good linearity. Adopting a large number of advanced technology and precision components and materials, and carrying out a professional structural design, the device is small in size, light in weight, full-featured, easy to carry, and it can work after booting, and the flow test is very convenient.

4、It can complete a variety of large-scale and complex calibration tasks with a high degree of automation. It can easily test and scan various protection settings, perform failure playback, store test data in real time, display vector graphics, and print reports online.

5、It is equipped with an independent 110V and 220V dedicated DC power output, which is convenient for on-site inspection and use.

6、The new generation LDJB-1600 tester is equipped with 10-channel open-in and 8-channel open-out, which is convenient for preparing self-input test. The input contacts are empty contacts and compatible with 0～250V potential contacts, which can be intelligently and automatically identified.

7、Provide various automatic test software modules and GPS synchronization trigger test (optional), etc.

8、It can complete various complex calibration work, can easily test and scan various protection settings, and perform fault playback. Can store test data in real time, display vector diagrams, print reports, etc.;

9、The design of the heat dissipation structure is reasonable, the hardware protection measures are reliable and complete, and it has the power supply soft-start function, the software performs self-diagnosis for faults and output lockout functions.
