Intelligent relay protection tester host built-in next-generation high-speed digital signal processor, true 16-bit DAC module, new modular high-fidelity high-power amplifier, comes with a large-screen LCD display and flexible and convenient rotation mouse controller has strong features , Most tests can be performed, the advantages of simple operation, high reliability, high performance and price ratio. It is a good tool for protecting workers.
Features:
1. Intelligent host, the host uses a high-speed high-performance digital signal processor with fast operation speed, transmission frequency bandwidth, and can generate high-density fitted sine wave of 360 waves per week for the fundamental wave. This is the highest level in the current output method of the same type. Due to the large number of points, the fidelity of the waveform is extremely high and the distortion is extremely small. Especially when harmonics are output, a high density of 60 points per week can be achieved even for 6th harmonics and 300 Hz. The device is operated by a large-screen LCD display with a convenient and flexible rotary mouse. It can complete most of the test verification work in the field, and can test various relays (such as current, voltage, inverse time, power direction, impedance, differential, low-cycle, synchronous, frequency, DC, middle, time, etc.) and microcomputer protection. , and can simulate a variety of complex transient, permanent, transitional faults for the entire group of tests.
2. 16-bit DAC chip 16-bit high resolution ensures high accuracy of the fitting waveform and good linearity. The small signal output also guarantees minimal distortion.
3. Intelligent relay protection tester Large-screen LCD display The machine adopts a 320×240 dot-matrix large-screen high-resolution graphic LCD display. All operation procedures are set on the display. The operation interface and test results are displayed in Chinese. Clear and intuitive.
4. The “fool†operation uses an advanced controller “rotating the mouseâ€, which greatly simplifies the structure of the operating part, and is easy, fast, and easy to grasp.
5. Intelligent relay protection tester The new high-fidelity amplifier output stage adopts new high-power modular high-fidelity power amplifier components, which can be used for current output and voltage output, and have large output power. Each phase voltage can output up to AC100V, current triple output. Up to AC90A. Good accuracy and high reliability.
6. Current and voltage directly output phase voltage and phase current adopt DC type power amplifier output mode, which can directly output AC voltage, AC current, DC voltage, DC current, and variable angle and frequency, and can superpose 0-6 harmonics.
7. Self-protection adopts a reasonable design of the heat dissipation structure, and has a variety of reliable and complete protection measures and power soft start, and certain fault self-diagnosis and locking function.
8. Rich contacts have 7 contact inputs and 2 empty contact outputs. The input contact is an empty contact and 0-250V potential contact compatible, which can be automatically and intelligently identified.
