A bench power supply is an essential piece of equipment if you do a lot of electronics or other powered projects on your bench and need a reliable source of power at different voltages. They are very useful tools in testing circuits, as they allow you to adjust the voltage to a specific value depending on what project you are working on. A variable DC bench power supply also allows you to set a maximum current, so if there is a short circuit in your project the bench supply will shut down hopefully preventing any harm to some components in your project. Bench power supplies are versatile, accurate and stable and don’t cost too much.

When it comes to power you have 4 units to be aware of, Current, Voltage, Power and Resistance. It's very important that if you are supplying your circuit with some voltage, your supply can keep up with the current drawn.

### Types Of Power Supplies

There are two basic types of power supplies in common use: linear and switch-mode. Both are available for use as bench DC power supplies.

**Linear power supplies** operate by rectifying AC line power to create DC and then filtering and regulating it to produce a user-selectable voltage or current levels. Linear supplies are heavier because the 50 Hz or 60 Hz transformer and associated filters are physically larger.

**Switch-mode power supplies** start out the same way, rectifying and filtering AC line input voltage, however, they chop (or "switch") the DC into high-frequency AC. Switch-mode power supplies are significantly smaller, lighter and more efficient than linear power supplies, so they have replaced linear supplies in many applications.

Dual Power Supplies | RS

<p>The dual power supply sits on your benchtop and is useful in the design and testing phase of your electronic circuit. It is widely used by electricians, engineers, and students in laboratories and industrial facilities. The dual bench power supply is used to provide two variable or fixed voltages. Dual output bench power supply is also used to provide two variable or fixed currents. Depending on the power supply of choice, it can be used to supply Alternating Current (AC) or Direct Current (DC). The dual output voltage is electrically isolated from the high input voltage provided by the power supply's transformer. Dual bench power supply overcomes the drawbacks of single output power supplies when two outputs are needed to power your electronic circuit. For example, operational amplifiers has two rails, a dual output bench power supply can then be used to provide the appropriate negative to positive rail-to-rail supply voltage to power your operational amplifier circuit. Dual bench power supply can also be handy when you need a regulated supply voltage for dual generators without having to take the other one offline. If you are looking to power your circuit without a battery, you may well use a voltage regulator that can be powered by a dual power supply.</p>

Keysight Technologies Bench Power Supplies | RS

<p>Power through circuit testing with a bench power supply. These powerhouses convert mains alternating current into direct current to provide an uninterruptable power supply with which you can complete your testing tasks. They're commonly used by electrical engineers in design and development laboratories and repair workshops, as the current can be manually specified to test for proper function in electrical circuits and devices. Keysight Technologies bench power supplies feature integrated over-current and over-voltage protection, which means that you can keep on testing without fear of damage to the circuit or device you're testing, saving you time and money. Many Keysight Technologies bench power supplies are also compatible with PathWave BenchVue software, which allows you to easily control the device from your computer.</p><h2>What different types of bench power supply are there?</h2><p>Bench power supplies can be grouped into one of two types based on how they convert current.</p><ul><li>Linear bench power supplies convert mains alternating current into direct current using a linear regulator. This is an older technology and as such, it isn't very efficient, with some energy lost as heat. They are, however, generally cheaper and are very reliable.</li><br><li>Switch-mode bench power supplies convert current using a switching regulator. This newer technology works similarly to the linear regulator, but instead switches the mains alternating current into a higher frequency alternating current. These bench power supplies are more efficient, however they're also generally more expensive than linear bench power supplies.</li></ul><h2>Which bench power supply is best for me?</h2><p>The best bench power supply for you depends on the kind of testing you'll use it for. When choosing a power supply unit, it's important to consider the following options:</p><ul><li><strong>Analogue or digital:</strong> Analogue models display current readings using a dial and scale, whereas digital models use a screen to display the value.
