Description: Filter capacitor: used to filter out the ripple left after switching power supply rectifier, so that the output of the DC more stable, so that the power supply performance is more stable. Pure copper coil inductance: in fact a bi-directional filter, on the one hand the signal line common mode electromagnetic interference, from the role of EMI filter; the other hand, suppress itself No external electromagnetic interference, to avoid the use of other nearby electronic equipment, so that the camera image more stable. Safety capacitor: capacitor failure will not lead to click, do not endanger the safety of the body to suppress the role of differential mode interference, so that the power supply more stable. Foot transformer: power foot, high efficiency. Import IC chip: integrated regulator, from over-current protection, over-voltage protection, overload protection. Specification: material: metal Product details Size: 92x190x40mm Applies to: 3D printers Package Includes: 1x Power Supply
