The control options for voltage (about 1.5 to 30V) and the maximum current of 2A (without heat sink) convinced me to use these small and inexpensive voltage regulator. The voltage can be adjusted at least to 1/10 V exactly; actually even finer. Have the regulator used, for example a 5V, 300mA to operate consumers at a 11V battery; while the controller has not (at least not noticeably) heated.
The input and output cables must be soldered. For permanent installation, the controller has two holes (approx 3mm) for example Schauben. So not a plug-and-play, a little craftsmanship and a soldering iron should bring if you want to use the controller.
Will the regulator to buy back (at the price I have no less than five found me on stock) and highly recommend him.
