China wholesaler indoor sp-100 transformer power supply

SP-100 is a range of enclosed power supply units featuring universal AC input and built-in power factor correction (PFC).

The SP series ranges from 75 ~ 240W, it has a wide range of protection functions against over/under voltage, over current, overload, overhead, and over temperature, as well as short circuits.

Either cooling by free air convection (SP-75 / SP-100 / SP-150) or cooling via a built-in DC fan (SP-200 / SP-240).

Series options: SP-75, SP-100, SP-150, SP-200, SP-240 SP-320 SP-500 PSP-600.
