main property

Protection: has a good self-protection function, in the DC current flow is large, the voltage is too large, no-load or load short-circuit, can automatically cut off the power supply to maintain the cut-off state, after the fault disappears, can also automatically restore the normal power supply function.

Stability: The output direct current is required to be stable, basically no fluctuation, that is, +12V, -12V, +5V, -5V four groups of power supply voltage and current are normal, otherwise it will affect the work of the host.

Heat dissipation: The built-in fan of the power supply has a large air volume, which can fully diffuse the large amount of heat released when the power supply is working, and extend the service life of the power supply.

Anti-interference: Good quality power supply is not affected by other electrical equipment switching. When the power supply with low anti-interference ability is turned on by other electrical appliances, the microcomputer may produce abnormal phenomena such as self-hot start. Low noise: strong components, stable operation of the power supply fan, no noise during work. The power supply with high noise is mostly caused by the vibration of the component, the imbalance of the fan blade, the eccentricity of the shaft or poor lubrication, and the use of the power supply with high noise is also easy to fail.

Compatibility: It should have standard power supply specifications, must meet the functional parameters of the standard switching power supply (shell size, fixing screw position is the same, suitable for various standard chassis), and provide standard stable voltage and current.
