Features of High-Frequency Power Supply Cores:
♦ High saturation magnetic flux density - effectively reduces the volume of the transformer
♦ High permeability, low coercivity - toroidal cores greatly improve efficiency, reduce excitation power, lower iron loss and copper loss
♦ Low loss - this prevents temperatures from rising in the high-frequency power upply core
♦ Excellent temperature stability - can work within a -55 ℃ ~ 130 ℃ temperature range during long term operation

Applications:
♦ High-frequency induction heating power supply
♦ Inverter welding power supply
♦ Communication power supply
♦ UPS power supply
♦ Laser power supply
♦ Electrolytic plating power
