The FA-405 is a 200 W Power Supply that provides a continuous output. It is adjustable from 0 to 40 V and from 0 to 5 A. The power supply has over-voltage, over-current, overpower and over-temperature protections, what provide a safety work environment for users. A special button allows blocking controls for greater safety and it prevents settings from unintentional changes. The incorporation of a rotary knob as well as the buttons to program incremental changes (in percentage) provide a way of use really easy, which is uncommon in programmable power supplies. The control of the power supply is totally digital. It has a RS-232C interface for remote programming by means of a PC.
