Switching power supply 24v, also known as Switching power supply 24V, is a type of high frequency inverter switching power supply. Switching power supply 24V through the circuit control switch tube for high-speed pass and cut-off. The direct current is converted into high-frequency alternating current and supplied to the transformer for transformation, thereby generating the required one or more sets of voltages!

It is often used as a dedicated stable DC power supply for pressure, temperature sensors, rotary encoders and other testing instruments. Many manufacturers produce and distribute this kind of Switching power supply 24V products. The circuit of the whole machine is assembled in a metal shell that is easy to install and has good electromagnetic shielding. The input/output terminals are convenient for line connection, with low failure rate and poor tolerance. Industrial environment.
The working principle of Switching power supply 24V is:
1. The AC power input is rectified and filtered into DC;
2. Control the switching tube by high-frequency PWM (pulse width modulation) signal, and add that DC to the primary of the switching transformer;
3. High-frequency voltage is induced in the secondary of the switching transformer, which is rectified and filtered and supplied to the load;
4. The output part is fed back to the control circuit through a certain circuit to control the PWM duty cycle to achieve the purpose of stable output.
The Switching power supply 24V circuit is a DC-AC-DC inverter circuit. It is a voltage and power converter that converts DC voltage and power into pulse voltage, and then rectifies it into another DC voltage. The input and output voltages are isolated by a switching transformer, which plays the role of power transmission and voltage/current conversion. The switching transformer in the circuit of this machine is a step-down transformer. The whole machine is composed of mains rectifier filter circuit, PWM pulse generation circuit, inverter power switch circuit, secondary rectifier circuit of switching transformer, voltage stabilization control and overload protection circuit.
