What can you do with a bench power supply?
A bench power supply is very simple to use. These instruments connect to a DUT via leads that are inserted into the instrument panel. Using the front panel display, engineers can set voltages or current levels to power the DUT. Most bench power supplies can operate in two modes: constant voltage and constant current.
Can you use a 12V adapter for 9V keyboard?
Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. Voltage is only one part of the picture and even if you get the voltage right, it’s possible for a power supply to ruin your pedal.
Why do I need a bench power supply?
Why do you need a bench power supply? A bench power supply is a really practical tool when it comes to circuits. It allows you to power your circuits before they are finished, to test individual circuits, to experiment, etc. This way, you don’t need to have a specific power supply for each project you want to test.
What happens if you plug a 12V into a 9V?
You can’t use a 12V adapter to power a 9V guitar pedal. A pedal that only handles 9V can be destroyed by using a 12V adapter. It’s possible for a power supply to ruin your pedal even if you get the voltage right.
How do I convert 12V to 9V?
12v to 9v converter using resistors as a voltage divider: Components required: One 12v battery, 300-ohm resistor, 1k resistor, some wires. It is just a voltage-divider circuit.
What is the best bench power supply?

What’s the difference between DC and DC power adapters?
Likewise, each electronic device is specifically designed to accept a certain DC input. The key is to match the DC output of the adapter to the DC input of your device. Determining the outputs and inputs of your adapters and devices is the hard part. Power adapters are a bit like canned food.
What kind of AC adapter do I need for battery charger?
Basically, it converts your mains power AC 110-240V AC into a smaller usually DC voltage that your small device needs to operate. Often these are required for charging or powering battery operated devices.
How to choose the right AC adapter for your device?
Choosing the right adapter specs. 1 The adapter output V matches the rated input V of the device. 2 The adapter output is greater or equal to the devices rated mAh or A. 3 The plug fits into your device and has the correct polarity.
Which is the correct voltage for an AC adapter?
It is important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. The most common are 18V, 12V, 9V, 6V, 5V and 3V. Once you have confirmed the voltage of the device we need to find the amount of current that it uses.
