These open style transformers have a primary voltage of 120VAC/60Hz and can be used for small electronic projects and designs. With a center tapped secondary they are ideal where the output needs to be rectified to DC.
The AK-20 is an action-packed student power supply kit. Once assembled it is not only useful but also visually stunning.It comes with an attractive acrylic clear case and a three digit seven segment voltage readout. Includes a power supply, cord and output leads with alligator clips. Adjustable 2 Watt DC power supply with an output voltage range of 1.25 to 12VDC Input voltage is 115VAC.
This is a high quality power supply with a continuously variable regulated output voltage adjustable from 0 and 30V DC. Its design is based on three Op‐Amps and incorporates anelectronic output current limiter that effectively limits the output current to from 0 to a maximum of 1.5A.
