As Electronics tinkerers, we know that different types of electronics and electronic circuits require defined and specific voltage ratings. This is because voltages are typically used to excite or activate various different components and electronic assemblies, from simply making LED’s glow to allowing transistors to become conductive, and hobbyist or consumer electronics are often designed with pre-set voltage requirements, with voltages like 5V, 12V or 24V being common standards.

Unfortunately, because of these specific and defined voltages that we commonly use, you can’t simply grab a random Power Supply from the drawer and use it to power any electronics. Instead, you need to supply the electronics with the precise voltages that they need, so that they can operate as expected, and not blow up in a spectacular way. Fortunately, whether your electronics use a common voltage range or a unique voltage that is hard to come by, you can get Voltage Regulators such as this LM2596 Adjustable Step-Down Module with Display, which take an incoming high voltage, and converts it down into an outgoing lower voltage. This allows you to take, for example, a 24V DC power supply, and convert the voltage down to the level you need, whether it’s 5V, 12V or even 16V DC, conditioning the power to be usable for your electronics – and to avoid any unnecessary (but awesome) explosions or damage.

Compared to the rest of the Voltage Regulators we stock, these units are quite unique in the way that they also offer an onboard 7-segment display, with a built-in button for switching between the input and output voltages. This means that it can be used both as a basic multimeter to test incoming voltages, but can also be adjusted to whatever voltage you need without requiring a multimeter to test outgoing voltages.

If you’re a thrifty Maker or have been looking for great ways to use your own phone chargers and power supplies for new projects, then consider getting yourself some of these awesome LM2596 Step-Down Buck Modules, or any of the other Voltage Regulators we offer.
