SUNBOW GROUP

 

●Cores of distribution transformers (50-60Hz)

●Cores of medium frequency power transformers (400Hz-15KHz)

●Cores of switching power supply transformers (Below 15KHz)

●Cores of filter reactors, filter and energy storage inductors, and power factor correction (PFC) inductors for (Below 50KHz)

●High-frequency rectangular cut cores of output inductors and transformers in switch mode power supply(SMPS), uninterruptible power supply (UPS) etc

●Cores of saturation reactors and pulse compressors

 

 

●Highest saturation magnetic induction among amorphous alloys ——Minimize component size

●Low coercive force ——Improve component efficiency

●Low iron loss (1/3 to 1/5 of silicon steel sheets) ——Reduce component temperature rise Excellent temperature stabilit
