What Are the Common Uses for a 12V Power Supply?

A 12V power supply is a common component in a wide range of devices. Common uses include network switches, computer peripherals, telecommunications, fibre optic networks, voice data and analogue communications, instrumentation, power industries, medical devices, and motor control. Read on to learn more about the various uses of a 12V power supply.

Unregulated 12VDC Power Supplies

Unregulated 12VDC power supplies are not always the best option for powering your devices. A regulated supply has a voltage regulator, which monitors the voltage from the battery. This type of power supply is necessary for many devices and technologies that require a constant voltage. They also are more economical.

These power supplies are used to power household electronics. Their output voltage is not regulated and can cause problems with your load. If you're using them for electronic devices, make sure they're matched to the device they're powering. If the voltage and current aren't the same, you'll experience issues with output or even overheating.

Fortunately, there are a few good alternatives to unregulated power supplies. One of the best options is the BVU Series. This series offers flexible configurations with adjustable input taps. In addition, the BVU Series' floating output makes it easy to place in series with other DC power supplies.

High-Efficiency 88% Switching Power Supply

A High-efficiency 88% switching power supply has a low standby power requirement and high efficiency. It has multiple protection features such as over-power protection and soft start. This type of power supply can operate over a wide input operating voltage range. Furthermore, it uses a quasi-resonant valley switching technology for maximum efficiency. It delivers a total power output of 25 W.

Low Ripple 12v Power Supply

A low ripple 12V Power Supply has a low ripple voltage. The amount of ripple on a power supply's output waveform depends on the characteristics of the load. A smaller load resistance will have less ripple, while a higher load current will create more ripple. If the ripple voltage is too high, it will cause the load to overheat and cause inefficiency. To reduce the ripple, you can add a filter capacitor to the output power supply.

Low ripple power supplies are available in both fixed and variable output voltages. These power supplies are ideal for use with electronic components. They have low noise levels and are ideal for low-power consumption applications.

Low EMI 12V Power Supply

A 12V power supply is the first module in a power supply chain, putting it at high risk of transient surges. Fortunately, manufacturers have come up with innovative ways to mitigate EMI. These include integrating an active EMI filter (AEF) into the input of the power supply and using dual-range spread-spectrum technology. These solutions reduce EMI by up to 55 dBuV across multiple frequency bands.

The latest low EMI buck converters can deliver ultra-low quiescent current and EMI. These power supplies also come with adjustable Under voltage lockout points and optimized pinouts to minimize AC switching current loops and system noise. The AP63203 and AP63205 units have a unique design that reduces EMI through a simplified PCB layout. These converters also have fixed 3.3V and 5V outputs, which further minimize the number of external components.

Affordable 12V Power Supply

If you're looking for a quality yet affordable 12V power supply, there are a few options available. The EVGA Supernova 550 G3 has a 550W output and provides 45A on the 12V rail. Its modular design means that you can choose exactly the components that you need, and it has an 80Plus Gold rating. It also has a five-year warranty.

The TELECOM-SEALED Series TM 12V AC DC Power Supply is a great choice for anyone who wants reliable power under any conditions. This line of affordable power supplies can endure the harshest conditions and can even be submerged in water.
