Czecho There are three elements in the procurement of industrial control power supply(3)
The high-voltage power module will generate a very high voltage during operation. If someone touches it, the consequences are unimaginable. In order to ensure the safety of employees and avoid safety risks, it is necessary to understand the insulation when purchasing high-voltage power supplies. Only by ensuring that the insulation is good enough, can some unnecessary troubles be avoided.
(1) After opening the package, it is necessary to carefully check whether the identification of each terminal is in line with the instructions that are brought along with it, and whether it is in line with the requirements of the order contract. If it does not match, you should immediately contact the production or sales unit to discuss how to deal with it.
(2) As the first step of installation, the metal casing of the module power supply must be grounded reliably to ensure safety, but the casing should not be connected to the zero line by mistake.
3. Make sure the 48V input power supply has multiple certifications.
Unlike other parts, there are many certifications for high-quality power modules, such as ISO9001.CE.RoHS is the certification required for power modules, we choose never to suffer from this, because everything can be fraudulent, qualifications cannot be fraudulent .
In short, the high-voltage 48V input power supply module must pay attention to the above three elements, and only by paying attention to these problems will not suffer losses, otherwise it may lead to safety risks.
