FAQs 6

Why is the error led on a DC power supply on?

In this case, the "Error" LED on a DC power supply has turned on. Your troubleshooting task is to determine if the problem is the power supply, the input supply voltage, or a load change on the demand side. You can do this by checking the AC input voltage and the DC output voltage.

Should a power supply be tuned to a DC load?

Furthermore, even if the load’s current only varies within the limited range, the power supply must be tuned and tested against the “load step response”, using a DC load.

How to troubleshoot a DC power supply?

Troubleshooting electrical components is a necessary part of keeping equipment functioning. The best tool to use for preliminary troubleshooting in a DC power supply is a digital multimeter (DMM). Digital multimeters are easy to use and can measure voltage, which is important for pinpointing problems with a DC power supply.

How do I know if my power supply is DC?

Identify the DC output terminals of the power supply. These are usually marked with a “+” for the positive and a “-” for the negative. e. Touch the black probe to the negative (-) terminal and the red probe to the positive (+) terminal of the DC power supply. f. The multimeter will display the DC output voltage.

How does a DC load work?

To put it simply, a DC load applies load pulses periodically (for instance: low current level: 1A, high current level: 3A) to the supply output while the output voltage is monitored for any ringing.

Why is my power supply output voltage unstable?

If you design/repair a power supply and the output voltage is unstable, then one probable reason could be an incorrect switching frequency. The switching frequency plays a very significant role in calculations and component values. A significant drift from the calculated frequency or any instability can cause the output voltage to fluctuate.
