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>

It is crucial that, if you are supplying your circuit with voltage, your supply can keep up with the current drawn. Some key features that bench power supplies offer include:<ul><li>Variable voltage output: Enables users to match the voltage requirements of the circuit or device.</li><li>Regulated output: Consistent power delivery is ensured through a regulated output voltage.</li><li>Current limiting: Limiting the maximum output current protects the circuit or device under the test from any damage caused by large excessive currents.</li></ul><h2>How to select a bench power supply?</h2>If you are supplying a circuit with voltage, it is crucial that your supply can keep up with the current drawn. There are four units to remember when it comes to power; voltage, current, power, and resistance. When it comes to selecting a bench power supply, there are some factors to consider to make sure that your specific requirements are met. Some key points to ensure when choosing your bench power supply include:<ul><li>Determining the range of voltage and current required for your projects.</li><li>Adjustable voltage and current settings to accommodate a variety of circuits and devices.</li><li>Consider if you need a single or multiple-output power supply.</li><li>Confirm whether programmable settings, digital displays, or other advanced features are required.</li><li>Ensure safety features such as overcurrent and overvoltage protection and short-circuit protection.</li><li>The correct form and size factor necessary to ensure it integrates well with the existing equipment.</li></ul><h2>Types Of Power Supplies</h2>Aim-TTi offer a vast range of bench power supplies, including:<ul><li>Adjustable power supply</li><li>Auto ranging power supply</li><li>DC power source</li><li>Laboratory power supply</li><li>Programmable DC power supply</li><li>Triple output DC power supply</li></ul><h2>Applications</h2>Aim-TTi bench power supplies can be used across many fields for a variety of applications, including:<ul><li>Education and training</li><li>Research and development</li><li>Repair and maintenance workshops</li><li>Laboratories</li><li>Battery charging and testing</li><li>Device characterisation and validation</li></ul>
