MSF-20
Description:
MSF-20 series Power supply is a mini-type enclosed power supply
It is a high-price-to-performance power supply solution for different industrial applications.
The MS series operates at a high efficiency of up to 80% and features a metallic mesh case that enhances heat dissipation. The whole series can operate at -10℃ through 50℃ under air convection without a fan.
