Can the 24v switching power supply be adjusted to 19.8v?

The 24v switching power supply cannot be adjusted to19.8V. The rated voltage of the 24v power supply is 24v. When the 24v power supply supplies power to supporting appliances, the actual output voltage is less than its rated voltage, which is between 20 and 22v, so the actual working voltage of the 24V power supply is normal, and the highest can be adjusted to about 22V, and the lowest can only be 20v.

Working principle of switching power supply

Switching power supply mainly uses modern power electronics technology to maintain the stability of output voltage by controlling the on-off time ratio of electronic switching devices. Generally composed of PWM (pulse width modulation) control IC and MOSFET, it has the characteristics of small volume, light weight, low power consumption and high efficiency. At present, it has been widely used in military equipment, industrial automation control, medical equipment, digital products and other fields.
