Many household products and household smart products will use power supply or control box for power supply and control. There are many standards for UL certification of such control boxes, such as UL 62368, UL 508, UL 1310 and UL 60730. Each UL standard does not focus on the safety assessment of products. In this article, Ankejie will briefly analyze the situation of UL certification for power supply and control box products. UL 60730 is more appropriate.
UL 60730 this standard, and the test focuses on the safety assessment of the control function. If the power supply box has a control panel and the control panel is the main function of this product, UL 60730 this standard can be considered for UL certification.
the electronics industry is becoming more and more subdivided. Most of the time, people will choose a standard power supply, and then design a control box with low voltage input and low voltage output to control electrical products. This type of control box is UL certified, and UL 60730 is very appropriate.
if the locked-rotor protection and other functions of the terminal electrical products are realized through the hardware of the power supply or control box, and it is necessary to evaluate the reliability of this function realized by the hardware, then when the power supply or control box is UL certified, UL 60730 can only be used for UL certification.
if the protection functions of terminal electrical products such as locked-rotor protection, anti-pinch protection, overload protection and temperature control are protected by programmable electronic circuit systems, such software used to protect the safety of products and personnel must be evaluated to verify its reliability, then when the power supply or control box is UL certified, UL 60730 can only be used for UL certification.
