Frequently asked questions
Can I use the fixed 5 V channel to power a microcontroller?
The 5 V channel is intended for digital circuitry and peripherals. Check the maximum current of CH3 in the manual, since the listing does not state it.
How do I set the current limit safely?
Adjust the voltage and the maximum current on CH1 or CH2 before connecting the load, and start with a low current limit when testing a new circuit.
