  • Datasheet:

We use these in our ATRs to supply a regulated isolated efficient regulated supply from a battery to our robot accessories. The board is spaced out on 0.1" or more grid that is easy to solder with no surface mount components. The board is about 1.25" square.

This is a regulator board. It has a terminal strip with a common ground, input, and Adjustable VDC output. Includes 3A fuse, filter, and power LED. It uses the adjustable version of Dimension Engeering's step down voltage regulators.

The Dimension Engineering DE-SWADJ 3 is a larger version of the DE-SWADJ adjustable step down voltage regulator. It can process 3A of current, typical ripple is 25mV and under ideal circumstances the regulator can be up to 96% efficient.

It continues the ease-of-use of the DE-SWADJ, making it simple to add an adjustable voltage source to a new or existing project with all the efficiency benefits of switch-mode power. The DE-SWADJ 3 is pin-compatible with the common 78XX family of linear voltage regulators, and has a small screw on top that allows you change the output voltage as your project evolves. It has integrated decoupling capacitors, so external capacitors are not generally necessary.

DE-SWADJ3 can deliver a maximum of 25 Watts.

The screw potentiometer on DE-SWADJ is worm-gear driven, so small vibrations and movement will not cause the voltage to shift. Use of glue to hold the screw in place is strongly discouraged and could damage the device.
