25W Linear Power Supply Regulated Power Supply (P3d without Screen) for DAC Speakers Hifi Uses

25W Linear Power Supply Regulated Power Supply (P3d without Screen) for DAC Speakers Hifi Uses

Features:
- Ultra low ripple and serene background
- LBO silver contact panel switches are easier to use than tailgate switches
- DC socket for Foxconn or USB socket as its output port
- On-board X and Y capacitors and flat copper wire inductors form a complete EMI filter circuit
- Ultra-low ripple circuit composed of precision reference, high-speed op amp and MOSFET output tube
- Using JLC Resistors, capacitors for Samsung, and diodes for SHIKUES
- Audio-grade low leakage current, low ESR in-line filter capacitors for ELNA and Nichicon
- EMI filter circuit: Adopt audio series capacitors for ELNA and Nichicon. Four second-stage main filter capacitor arrays and six third-stage CLC π-type filter structures reduce background noise and make music dynamics more powerful. 4pcs filter inductors for ELNA further improve the purity of the current
- Audiophile parts: using adjustable potentiometer for Bourns, thin film electrode capacitors for Philips Vishay BC. Military spec wafer resistors for Vishay boast high precision low temperature drift are used. MOSFET for Infineon with ultra low internal resistance
- Resistors for Vishay: Featuring low noise figure, high thermal stability, excellent inductive and capacitive reactance, they improve current quality and better sound quality
- EMI filter includes 2 X capacitors, 2 Y capacitors and 1 flat copper inductor. Add safety X capacitors between the fire neutral wire of the power supply and safety Y capacitors between the fire neutral wire and the ground wire. This can suppress power grid noise and high-order harmonics, as well as noise and high-frequency harmonics generated by switching power supplies, motors, etc. Improve the purity of sound quality and reduce noise caused by AC power interference
- Audio device: Its output adopts USB sockets. The input socket produced by Taiwan Rongfeng (the foundry for Furukawa from Japan)
- No ringing: The transformer is encapsulated with epoxy resin, which can reduce electromagnetic interference and leakage and eliminate the hum of the transformer
- Circuit structure: Adopt TL431 precision reference voltage with excellent performance, plus high-speed op amp and MOSFET power tube, ultra-low noise DC voltage regulator circuit, and 3-stage filter
- Diode for SHIKUES: Cleaner picture, richer sound quality details, and darker and purer background
- The input socket contains a spare fuse for easy replacement
- Inside the circular hole of Adj is the fine adjustment knob of the output voltage. Rotate the knob clockwise with a flat-blade screwdriver to increase the output voltage
