30V 5A Bench Power Supply Yihua 3005D

Yihua series of single power supplies for currents up to 5A are reliable and precise laboratory equipment with regulated and stabilized DC voltage and regulated (limited) current. The output voltage and current are adjusted using the + and - buttons on the main panel of the power supply. The power supplies are protected against the effects of short circuits and thus against overload and damage. Cooling is provided by the built-in fan. They are equipped with 2 readable LED displays. Power supplies can be used in design of electronics products, scientific work, in laboratories, on production lines and in teaching.
