Common problems in the use of power inverters?
UPS Chinese means “uninterruptible power supply”. The power UPS is specially designed for substations, with rectifiers and inverters as the main components, and the DC power supply system as the backup power supply. It provides constant voltage and constant frequency for core equipment such as monitoring systems, automation instruments, remote communications and microcomputer systems in the substation. Uninterruptible ups power supply unit. What are the common problems in the use of power inverters?
How should a power inverter choose a modified sine wave and a pure sine wave?
1. The two waveforms are different, the pure sine wave is relatively stable and equal to the mains, and the modified wave is the analog of the mains.
2. The correction wave is generally a resistive load. Pure resistive loads that work through resistive components are called resistive loads, such as: mobile phones, computers, LCD TVs, induction cookers, white woven lights, electric fans, rice cookers, electric fans, small printers, etc. are all resistive loads.
3. The pure sine wave is equivalent to the city electricity and can carry any electrical appliances, and is generally used for inductive loads. Electrical appliances with coils are called inductive loads, such as motors, compressors, relays, LED lights, refrigerators, freezers, air conditioners, etc. The power at the moment of starting far exceeds the rated power (about 3-7 times).
When the inverter is in use, if there is a shutdown or alarm, what is the reason?
1) Whether the power of the driven electrical appliance exceeds the rated power value of the inverter.
2) Whether the inverter is well connected to the battery and electrical appliances
3) If it is stopped during use, whether it is a temperature alarm, at this time, it can continue to be used after stopping for a period of time.
