So it is necessary to convert the available AC voltage of mains supply into D.C. voltage and can be use for operation of electronic circuits. The equipment which converts AC voltage into pure and stable DC voltage is called as a DC Regulated power supply.
What is the regulation in power supply?
Power supply regulation is the ability of a power supply to maintain an output voltage within a specified tolerance as referenced to changing conditions of input voltage and/or load. Most electronic equipment is powered from DC voltage derived from the unregulated AC mains voltage.
How do you troubleshoot a DC power supply?
First check for power and correct voltage on the input side of the power and supply. Then check the output or secondary side. If there is no power or the voltage reading is low disconnect the output wires with the power off. Then power up and recheck the output side.
How do I test a power supply with a multimeter?
- Plug the power supply back in and turn it on.
- Find a pinout chart for your power supply. ...
- Set your multimeter to the VBDC setting. ...
- Connect the negative probe of the multimeter to a ground (black) pin on the connector.
How do you test an electronic power supply?
Test Procedure Set the input voltage to the nominal requirement for your power supply. Set the output voltage load to its maximum rated value. Measure the output voltage (VOUT) with the calibrated voltmeter. Note that DC/DC power supplies typically have a set output voltage where AC/DC have a variable output voltage.11 ene 2016
How do I know if my power supply is faulty?
- Random computer crashes.
- Random blue screen crashes.
- Extra noise coming from the PC case.
- Recurring failure of PC components.
- PC won't start but your case fans spin.

How is DC supply connected?
The main job of an AC/DC power supply is to transform the alternating current (AC) into a stable direct current (DC) voltage, which can then be used to power different electrical devices. Alternating current is used to transport electric power all across the electric grid, from generators to end users.
How does an AC to DC power supply work?
The AC power moves into a transformer to change the voltage. After the power supply attains the correct voltage, the electricity travels to the rectifier where it converts back to DC power. As with AC-DC power supplies, DC-DC models may require regulators to smooth out the signal.
