Ultra-Low-Noise Bench-Mount Power Supplies

Change AC voltage to DC voltage to power extremely sensitive audio, measuring, and testing devices while keeping electronic interference—often called output or ripple noise—from passing on to the device. The lower the output noise value, the less interference the power supplies will create. Although they create less noise than other power supplies, these power supplies are larger, heavier, and give off more heat.

Designed with linear voltage regulation, these power supplies produce the same voltage regardless of changes in the input voltage or the amount of current being drawn. They are also known as linear power supplies.

View the output on a digital or analog display.

If you exceed the maximum load or current, all of these power supplies will shut down to protect both the power supply and the connected device.

With 1 Output Power Connection—Digital Display

Digital displays are often easier to read than analog displays, so you can quickly see if you need to make adjustments.

Over Temperature—Those with overvoltage or over temperature protection will shut down if you exceed the maximum voltage or temperature.

Bench-Mount Power Supplies

Convert AC voltage into the DC voltages needed to test, design, and prototype a wide variety of electrical circuits and equipment. These power supplies let you adjust the output to the exact voltage needed to power your equipment. You can also set limits on the maximum current to protect your equipment from damage. Keep an eye on the voltage and current drawn by your connected components with the digital display.

Since these use switching regulation, they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and won’t become too hot.

When these power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this won't affect most applications, this noise can interfere with other signals in extremely sensitive applications. The lower the output noise, the less interference it creates.

These power supplies are CE Marked, which means they meet European Union safety standards. If your power supply exceeds the maximum current, voltage, or load, they’ll shut down to protect both the power supply and the connected equipment. Some also protect against excessive temperatures.

Connect the banana plugs on your equipment to the socket output connections.

1 Output Power Connection—Banana Jack Socket

Output Voltage Selector Switch—Power supplies with output voltage selector switch let you choose either an adjustable output, which you control with a dial, or an output fixed at 13.8V DC.

Programmable Bench-Mount Power Supplies

Use your computer to remotely control these power supplies that convert AC voltage to DC voltage for powering electronics from simple prototypes to advanced testing equipment. All of these power supplies include a USB cable and Windows-compatible software to control, monitor, and record the voltage, current, and power outputs of your device. You can also create programs with up to 20 steps that change voltage and current outputs at set times. A selector switch lets you quickly choose up to three defined settings for voltage and current outputs. The power supplies have an auxiliary output connection, but it will take on the same settings as the primary outputs. View the outputs on their digital display.

These power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. If you exceed the maximum voltage, current, load, or temperature, the power supplies will shut down to protect both the power supply and the connected device.

Remote Voltage Sensing—Power supplies with remote voltage sensing check for any drops in the voltage as they send power to a device. If the voltage dips, they can compensate with extra power, so connected devices always receive the correct voltage.

Maximum Output Noise Peak-to-Peak—Maximum output noise is also known as ripple noise. When power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this noise won't affect most applications, it can interfere with other signals in extremely sensitive audio, measuring, and testing equipment. The lower the output noise, the less interference it creates.

Fixed-Voltage Bench-Mount Power Supplies


	Stud Terminal on Back

No need to adjust the voltage on these power supplies—they’re specifically designed to convert 120V AC to 13.8V DC. This voltage is common in radio transmitters, battery chargers, and automotive electrical systems, so these power supplies are often used to develop and test electronics that will be used in those applications. Since they are not adjustable, there’s no risk of supplying the wrong voltage and damaging your equipment. Power supplies have a stud terminal output connection to work with wire leads. Wrap the wire around the stud and secure with the included nuts, or attach alligator clips to the studs.

These power supplies have linear voltage regulation, which means they produce the same voltage regardless of changes in the input voltage or the amount of current being drawn. They are also known as linear power supplies. They have extremely low noise output, meaning that they keep electronic interference (also known as output noise or ripple noise) from being passed on to your device. However, these power supplies are larger, use more energy, and give off more heat than switching power supplies with a similar output.

If you exceed the maximum load or current, they’ll shut down to protect both the power supply and the connected equipment.

Overvoltage—Power supplies with overvoltage protection will also shut down if you exceed the maximum voltage.
