Specifications of DC stabilized power supply
Today, GVDA takes you to understand DC regulated power supply. In modern society, DC regulated power supply is generally widely used in the DC power supply of national defense, scientific research, colleges and universities, laboratories, industrial and mining enterprises, electrolysis, electroplating and other equipment.
Specifications of DC stabilized power supply
(1) Stability: When we input the voltage, when the change in the specified range, the change of the output voltage should be very small, generally less than 1%, the change of the input voltage will cause the change of the output voltage, which is called stability It can reflect the ability of the regulated power supply to overcome the change of the input voltage.
(2) Output resistance: When the load changes from no-load to full-load, the output voltage basically remains unchanged. The performance of the regulated power supply can be characterized by the output resistance. The output resistance is equal to the ratio of the output voltage change to the load current change, which reflects the change in the load. , the output voltage will maintain a constant capability.
(3) Temperature coefficient of voltage: When the ambient temperature of the DC regulated power supply changes, it will cause the output voltage to drift. A good regulated DC regulated power supply will effectively suppress the ambient temperature changes. The drift of the output voltage can maintain the stability of the output voltage, and the drift of the output voltage is represented by the coefficient of temperature.
(4) Ripple of output voltage: Ripple voltage refers to the AC component of 50Hz or 100Hz in the voltage, which is generally represented by the rms value or the peak value. After voltage regulation, the rectified ripple voltage can be reduced
