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>
