Mount these DC converters to DIN rails on fixtures such as industrial cabinets and electrical panels. By converting voltages, they let you connect power supplies to equipment that requires a different input voltage. They’re often used to power sensors or other components that require a lower voltage than surrounding equipment. Since they send a stable, consistent voltage to equipment, they can also be used to correct power supplies that send uneven voltages. All meet U.S. and Canadian, or European Union, safety standards.
If you exceed current limits, these converters will shut down to protect your equipment. Some converters have overvoltage or overload protection, as well.
The lower a converter’s maximum output noise, also known as ripple noise, the less electronic interference it creates. These converters will work in most applications.

DC to DC Converters

When your power supply sends out DC power at a higher voltage than you need, change to the proper voltage with these converters. They’re often used when a specific component, such as a sensor, requires a lower voltage than surrounding equipment. Use them to correct power supplies that send uneven voltages, too—they provide electricity at a stable, consistent voltage. They mount on flat surfaces, and are commonly fastened inside enclosures.
If you exceed the current limit, these converters will shut down to protect your equipment. Some converters have overvoltage protection, so they’ll do the same if you exceed voltage limits.
The lower a converter’s maximum output noise, also known as ripple noise, the less electronic interference it creates. These converters will work in most applications.

Logic Level Converters for Development Boards
![](/prerenderstable/mvPRE/contents/gfx/imagecache/489/4894n11-@halfx_637626312798149100.png?ver=imagenotfound)
Communicate between a development board and other components, such as sensors and actuators, that use digital signals at a different voltage. Connect your high-voltage power source and devices to one side and your low-voltage power source and devices to the other. These converters have four independent communication channels, each of which connects high-voltage devices to low-voltage devices. All channels are bidirectional, converting voltage from high to low and low to high, so they support protocols such as I2C that send data in both directions on a single wire. They’re often used between a 5V DC device and a 3.3V DC device, but will work with any voltages within the listed range. For fast prototyping, solder on headers and plug them directly into a breadboard. For a permanent connection, solder on wires.

Circuit Board Voltage Regulators
Safely power low-voltage components in circuits with a high-voltage source. These regulators turn high-voltage inputs into lower, more stable outputs.
Regulators with an adjustable output voltage let you fine-tune the output to best fit your circuit. To adjust the output voltage, connect them to two resistors (not included). The resistance values determine your output voltage.
Dropout voltage is the minimum required difference between the input voltage and your regulator’s output voltage.
