We designed and manufactured this 15VA linear fever power supply. On the one hand, all kinds of imported high-quality components are used in this 15VA linear power supply regardless of the cost. For example, the key core of the linear power supply adopts the brand new imported Talema 15VA sealing ring cattle, low noise L and T1086CT voltage stabilizing chip, low internal resistance LXZ electrolysis, imported large current rectifying bridge and other fever components. On the other hand, considering the reliability and safety of the power supply, we adopted the aluminum alloy shell with integrated heat dissipation and the output with CLC double filter in the design to ensure the safety, stability and heat dissipation performance of the power supply during long working hours.
