S2多系列开关电源在我所研究室的课题工作中广泛应用，效果良好。它采用交流电源直接整流、高频变换和脉宽调节制技术，甩掉了笨重的50HZ变压器，具有体积小、重量轻、效率高、输出电压保持时间长、不易输出过电压、性能稳定可靠等特点。此外，150W以上几种具有并联运行功能，
S2 multi-series switching power supply in the research work of my research room widely used, the effect is good. It uses AC power direct rectification, high frequency conversion and pulse width modulation technology, get rid of the bulky 50HZ transformer, with small size, light weight, high efficiency, the output voltage to maintain a long time, not easy to output over-voltage, stable and reliable performance, etc. Features. In addition, more than 150W with parallel operation of several functions,
