May I ask if the power supply of BeautyPower can be used for 45~440Hz, and if so, is there any other influence?
BeautyPower's standard products can generally be used in this frequency range. However, if the frequency of use is too low, the efficiency will drop. For example, when SP-200-24 operates at an input voltage of 230VAC and a rated load, when the input AC frequency is 60Hz, its efficiency is 84%, but if the input AC frequency drops If it is 50Hz, its efficiency is 83.8%; if it is too high, the PF value of the model with PFC function will decrease, and it will also increase the leakage current. At rated load, when the input AC frequency is 60Hz, the power factor is 0.93 and the leakage current is 0.7mA; when the input AC frequency is 440Hz, the power factor is reduced to 0.75, and the leakage current is increased to 4.3mA.
