Tag: dc power supply

Switching power supply (SMPS) modulates pulses of input voltage by closing and opening the circuit of electronic switching devices (such as transistor, field-effect transistor, and silicon controlled thyratron) to fulfill output voltage adjustment, automatic voltage stabilization, and continuous voltage conversion between DC/AC or DC/DC. Switching power supply is mainly divided in two types, DC SMPS and AC SMPS. Switching power supply is composed of main circuit, control circuit, detection circuit, and auxiliary power supply. Now it is widely applied to all kinds of electronic devices due to its small size, light weight and high efficiency.
ATO switching power supplies can convert full range of AC input to DC with protection of short circuit, overload and overvoltage, complying with safety & EMC standards. Besides, they are high reliability and long lifespan with favorable price.

How to choose a right switching power supply? Six tips will give you a guide of selecting a right SMPS power supply: voltage, power, load characteristics...
How to use a switching power supply properly? To use a SMPS power supply properly and in long service life, some suggestions are made for your reference.

When switching power supply blows a fuse, when there is no DC output or volatge output is unstable, when switching power supply has poor load capacity, how to do? Click it and then you will know how to deal with these problems as well as some repairing skills.
