UPC090AE01 DC AC Power

 The overheating protection of the heat dissipation plate of the inverter module is the main component that generates heat in the inverter, and it is also the most important and fragile component in the inverter. So, each frequency converter is equipped with overheating protection devices on the heat dissipation board. 3. The nominal power of the braking resistor for overheating protection is selected based on short-term operation. So, once the power is on for too long, it will overheat. At this point, the use should be suspended and reused after cooling. Alternatively, choose a larger power resistor. 4. The inlet and outlet of the cooling air duct should not be blocked, and the ambient temperature may also be higher than the allowable value of the frequency converter. Targeted solutions and improvement suggestions have been proposed, which has certain reference value for the application of frequency converters in practical engineering

 Attention should be paid to the interference problem of the frequency converter on the microcomputer control board. The user designed microcomputer control board has poor craftsmanship and does not comply with EMC international standards. After using a frequency converter, the conducted and radiated interference often leads to abnormal operation of the control system, and necessary measures are taken. Precautions for maintenance and upkeep of frequency converters in summer:

1. Check the operation status of the frequency converter, whether the voltage and current values during operation are within the normal range.

2. Carefully monitor and record the ambient temperature of the frequency conversion room, which is generally between -5 ℃ and 40 ℃. The temperature rise of the phase-shifting transformer shall not exceed 130 ℃. 3. Avoid areas with direct sunlight, moisture, and water droplets. Summer is a rainy season, and rainwater should be prevented from entering the interior of the frequency converter (such as through the air outlet of the wind duct). 4. Frequency converter installation: (1) Due to high temperatures in summer, ventilation and heat dissipation should be strengthened in the frequency converter installation site. Ensure that the surrounding air does not contain excessive dust, acids, salts, corrosive and explosive gases. (2) In order to maintain good ventilation, the distance between the frequency converter and surrounding obstacles should be ≥ 125px on both sides and ≥ 300px above and below. (3) In order to improve the cooling effect, all frequency converters should be installed vertically. To prevent foreign objects from falling on the air outlet of the frequency converter and blocking the air duct, it is best to install a protective mesh cover above the air outlet of the frequency converter. (4) When two or more frequency converters are installed in a control cabinet, they should be installed side by side (horizontally arranged) as much as possible. If vertical arrangement is necessary, a horizontal partition should be installed between the two frequency converters to prevent hot air from the lower frequency converter from entering the upper frequency converter.
