If the power consumption exceeds 100W for a long time, a fan must be added to enhance heat dissipation, otherwise the module will burn out! In the case of strong heat dissipation, long-term use should not exceed 200W. 300W refers to value, and no matter how much heat dissipation is strengthened, it cannot be used for a long time. Revised application scenarios for sine wave inverters The modified sine wave inverter can be applied to laptops, televisions, combination audio systems, cameras, and digital devices Code cameras, printers, various chargers, handheld computers, game consoles, DVD players, mobile Household therapeutic devices and other inverters with high output power can also be applied to small electric heating appliances such as electricity Hair dryer, electric cup, kitchen appliances, etc. But for inductive load electrical appliances such as refrigerators, drills Electric motors, compressors, relays, fluorescent lamps, electric fans, induction cookers, air conditioners, etc. are not suitable for use Correct the power supply of the sine wave inverter. Otherwise, it may cause damage to the inverter and related electrical products or Shorten the expected service life. For specific applications, it also depends on whether the inverter power matches the electrical power.
