SDN20-24-100C power supply is a kind of power supply equipment, which can stabilize the voltage within a set range. Switching mode refers to the mode of operation of the regulated power supply, through the switching mode, the regulated power supply can work at different voltages and current currents to adapt to different load requirements. 24V refers to the output voltage of the regulated power supply is 24 volts.

The characteristics of switching mode stabilized power supply mainly include:

Low power consumption, high efficiency: SDN20-24-100C switching mode, the transistor itself consumes less power, can achieve higher efficiency.

Small size, light weight: Because the switching power supply does not need a step-down transformer, its output transformer works at high frequency, and the volume is less than 50 Hz power frequency transformer, so the circuit is small and lightweight.

Wide voltage regulator range: The output voltage of SDN20-24-100C switching regulator power supply is regulated by the duty cycle of the excitation signal, and the change of the input signal voltage can be compensated by frequency modulation or width modulation. When the power frequency network voltage changes greatly, it can still ensure a relatively stable output voltage.

The circuit forms are flexible and varied: for example, there are self-excited and other-excited, there are width modulation and frequency modulation, there are single-ended and double-ended, and so on. Power developers can use the advantages of various types of circuits to design and develop switching regulated power supplies that can meet different application environments.

Serious switching interference: SDN20-24-100C power adjustment switch transistor working in the switching state, will produce AC voltage and current, through other components in the circuit to produce peak interference and vibration interference. If these interferences do not take certain measures to suppress, eliminate and shield, it will affect the normal operation of the whole machine.
