A DC power supply output a direct-current voltage that can be used to power electrical components and circuitry. The CSI3003X has three outputs, two that provide variable DC voltages in addition to a constant 5 volt and 3 volt output.
The Benchtop Power Supply can be used to power any small project that draws less than 3 amps. It is an invaluable resource when working on a new project or repairing old electronics.
No special PPE is required to work with the Power Supply. Always take care to zero the voltage before turning on the Power Supply.
The Power Supply is protected by current limiting. If a circuit attempts to draw too much power, an internal fuse will blow.
Basic LED Circuit
This is the electronics portion of the PI checklist. It provides an introduction to soldering, protoboards, LEDs, and resistors
Operational Amplifier Circuits
Operational amplifiers (Also known as op-amps) are very common circuit components that must receive DC power in order to function
How To Use This Tool
Figure 2 - Labels for referenceFor startup procedure and equipment operation, reference figure 2. Before connecting the DC power supply to a circuit, turn it on by pressing button 5, labeled “POWER.” Rotate knobs until both supplies read 0.0V and 0A. Zeroing the power supply ensures that a voltage higher than expected will not be applied to the circuit.

To power your circuit
- Follow start up procedure to zero the voltage.
- Connect required leads to the output and ground ports on the front of the power supply.
- Connect leads to circuit. Black to negative or ground, and red to positive. See figure 3 for an example.
- Power on the supply.
- Adjust voltage and current to desired value.
- Turn the knobs until the display reads 0.0V and 0.0A
- Disconnect your circuit from the power leads.
- Remove the power leads from the Power Supply
- Hang the leads back on the rack
- Clean up any used components or clutter from the workbench
Power supply is not turning on
- Disconnect power supply from circuit
- Check that the power supply is plugged into an outlet.
- If the supply is plugged in and still not receiving power, change it to another outlet.
- If power supply is connected to the electronics bench, ensure the bench is powered.
- If problem persists, ask a prototyping instructor for help. The internal fuse of the CSI3003X III may need to be replaced.
