Mongolia There are three elements in the procurement of isolated module 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.

3. Make sure the LED advertising screen power supply has multiple certifications.

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

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 LED advertising screen 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.
