Chinese Professional Smps Power Supply - 500W Single Output Switching Power Supply S-500 series – Leyu Detail:

1, small power consumption, high efficiency, switching power supply circuit, transistor V excitation signal under the excitation, alternatively work in the on-off and cut-off on-off switching state, the conversion speed is very fast, the frequency is generally about 50KHz, some advanced technology countries, can do hundreds or nearly 1000KHz.This makes the switching transistor V power consumption is very small, the efficiency of the power supply can be greatly improved, its efficiency can reach 80%.

Switching power supply

2, small size, light weight.It can be seen clearly from the principle block diagram of the switching power supply that there is no light power frequency transformer.Because the dissipated power on the adjusting tube V is greatly reduced, the larger radiator fin is omitted.Because of these two reasons, the switching power supply is small in size and light in weight.

3, the voltage range is wide, the output voltage from the switching power supply is adjusted by the duty ratio of the excitation signal, the change of the input signal voltage can be compensated by frequency modulation or width modulation.In this way, the stable output voltage can be guaranteed when the power frequency network voltage changes greatly.So the switching power supply voltage regulator range is very wide, the voltage regulator effect is very good.
