Compared with IGBT-based DC switching power supplies, MOSFET-based switching power supplies have a higher switching frequency, making this series Benchtop DC power supplies can use smaller semiconductor devices and LC filter units while ensuring low ripple, high precision, and fast response characteristics of the Benchtop Laboratory Power Supplies DC output. Which gives more space to use a smaller chassis size at the same output power, resulting the high-power density feature of this series Benchtop AC DC power supplies.
The main design purpose of this series of Bench AC-DC power supplies is to fulfill the needs of small laboratory test, precise experiment and universities.
At present, this series of Bench AC DC power supplies below 1KW adopts desktop chassis to match laboratory applications, they are mainly used in LED testing, small electroplating, heating of new materials, electrical component testing and other applications.
