The so-called inverter-type regulated power supply is also called variable frequency power supply. The inverter power supply adopts 16-bit Motorola processor control, high-frequency PWM design, and imported Mitsubishi 1GBT. The efficiency is over 85%. The reaction is fast, and the reaction time is within 2ms for 100% load/load. The variable frequency power supply has strong overload capacity, and the instantaneous current can withstand 300% of the rated current. The waveform is pure, the frequency is high and stable, and no disturbing magnetic waves (EMI, EMC) are generated. The variable frequency power supply is not only the R&D and laboratory, the best power supply for the measuring room, but also the standard power supply for EM/EMC/safety testing.
å˜é¢‘The variable frequency power supply has the characteristics of strong load adaptability, high efficiency, good stability, good output waveform quality, simple operation, small size and light weight. This variable frequency power supply is designed for different power types around the world. Users can not only simulate their voltage and frequency (47~63Hz) for testing applications. Among them, the medium frequency power supply specially designed according to the national military standard can also support 400Hz frequency defense military detection and avionics. And navigation, communications and other applications.
â—‡This variable frequency power supply can be used normally for a long time regardless of whether it is pure resistive, capacitive, inductive or non-linear load. Three-phase can be used in single phase. The voltage and frequency can be adjusted with load. Some of these models can be set with a power-on password to facilitate safe use in the production hall.
Activated Carbon is a very small carbon particle with a large surface area, and there are even smaller holes in the carbon particle-capillary. This capillary has a strong adsorption capacity, because of the large surface area of the carbon particles, it can be in full contact with gas(impurities). When these gases(impurities) touch the capillary, they are adsorbed and act as purifiers. The study of the surface area of activated carbon is very important. The detection data of the specific surface area of activated carbon is only true and reliable by using the BET method. At present, there are many instruments in China that can only be detected by direct comparison methods. Now it is also in China. It was eliminated. At present, multi-point BET method is used for specific surface area testing at home and abroad. The specific surface area measurement standards formulated at home and abroad are based on BET test methods. See the Chinese National Standard(GB/T 19587-2004)-BET principle for the determination of the surface area of solid substances. The specific surface area detection is actually a more time-consuming task. Due to the different adsorption capabilities of samples, the testing of some samples may take a whole day. If the test process is not fully automated, the testers can not leave at all times. And to be highly focused, observe the dashboard, control the knob, and inadvertently lead to the failure of the test process, which will waste a lot of valuable time for the tester. The F-Sorb 2400 ratio surface area tester is an instrument that can truly achieve the BET method detection function(with a direct comparison method). The more important F-Sorb 2400 ratio surface area tester is the only fully automated and intelligent surface area detection device in China so far., Its test results are highly consistent with international standards and have good stability. At the same time, it reduces human error and improves the accuracy of test results.
