    The difference between AC regulated power supply and DC regulated power supply is that DC power will not change, while AC power supply has a change cycle, AC voltage E = EMSinωT, EM is the peak value of AC voltage, i.e. the maximum value, while DC voltage is constant, AC power supply also has an effective value. According to the calculation of current thermal effect, the effective value is indicated or measured on the general nameplate or voltmeter, just because Alternating current is a periodic change, which can make the capacitor charge and discharge for a short time, so alternating current can pass through the capacitor and direct current cannot pass through the current.

    DC regulated power supply: Electronic device that can provide stable DC power for load. When the voltage or load resistance of the AC power supply changes, the DC output voltage of the regulator will remain stable. With the development of electronic equipment to high precision, high stability and high reliability, DC stabilized power supply puts forward high requirements for the power supply of electronic equipment.

    AC regulated power supply: Electronic device that can provide stable AC power for load. Also known as AC voltage regulator. The output is alternating current. All kinds of electronic equipment require a relatively stable alternating current power supply. Especially when computer technology is applied to various fields, the use of direct power supply from the alternating current grid without any measures can not meet the needs.

    Good power supply, easy to adjust voltage and current
    This is a very good DC power supply, it is very accurate and has a little button that looks like an LED indicator. I thought I had a problem with the unit until I realized that it was actually a button to turn on the output. When the output is turned on, the unit displays the voltage and current of the output.

    10A 30V DC power supply perfect for student
    I am a college student majoring in Electrical Engineering of Technology. This DC power supply is perfect for working at home on your circuits. Whether you didn't finish a lab, or just want the extra practice this device works brilliantly. It is adjustable from 0V-30V which is perfect for beginner/intermediate circuitry.
