The "MHFW Series" is a compact, general-purpose high-isolation DC-DC converter suitable for measurement and inspection equipment that requires high insulation between input and output. Due to the small inter-phase capacitance between input and output, it can reduce noise transmission. It allows for continuous voltage application and is suitable for devices where the voltage between input and output, such as motor drivers, may vary. With its wide input range, it is also suitable for battery-operated devices. 【Features】 ■ High voltage resistance ■ Low inter-phase capacitance / Continuous voltage application ■ Compliant with medical standards / Low leakage current *For more details, please refer to the PDF materials or feel free to contact us.

Output derating" is one of the rules for power supply usage and is a concept related to operating conditions and output power. If design progresses without considering output derating, various issues may arise, such as shortened lifespan, induced failures, and adverse effects on the entire system. This document focuses on output derating in equipment design and explains the impact of power supply installation direction and ambient temperature on the design. If you are concerned about power supply lifespan and safety, please take a moment to read this!

The key components that determine the lifespan of a power supply are "electrolytic capacitors" and "fans." Additionally, the lifespan of "solder" is also a factor that affects the lifespan of the power supply. If thermal design of the device is advanced without considering these factors, it may not reach the expected lifespan of the power supply, leading to unexpected issues such as increased maintenance frequency. This document focuses on the theme of "key components that determine power supply lifespan," providing explanations about the lifespan of each component. If you are struggling with extending the lifespan of your power supply or with device maintenance, please take a moment to read it!
