Weho mini-size 75w transformer switching power supply

WeHo’s MS-75 series Power supply is a mini type enclosed power supply which serves as a high price-to-performance power supply solution for various industrial applications.

In addition to the high efficiency up to 80%,the design of metallic mesh case enhances the heat dissipation of MS that the whole series operates from -10℃ through 50℃ under air convection without a fan.

White cap over the connectors for security setting of dust-proof protection for electrical shock

And we make transformers and power inductors by pure coppers all by ourselves,

Thick enclosure die-casting aluminium Case with good thermal conductivity

Internal EMI Filter Device, without signal interference, wide using in various fields
