Large hand-wound EI core transformer adopted linear power supply.
Overwhelming leeway and richness of expression.
isKennetn Wong, a high-end DIY audio company in Hong Kong, is renowned as a trance maker. A large EI hand-wound core transformer is used to support up to with a port meter.
isProvides overwhelming leeway and expressiveness.
The 15-24V specification model is designed to be used for amplifiers, DAC s, and other equipment for amplification and conversion of music signals. Therefore, the output can be stopped by the regulator's heat generation when used in switching hubs, HDD s, routers, and other devices that consume constant large currents There was.
In designing the 5-12V specification, a 12V and 5V tap on the secondary side of the transformer reduces the heat loss generated during voltage conversion in the regulator, and improves the allowable current value by connecting two regulators in parallel. 5-12V specifications can be used for amplifiers, DAC s, network audio devices, etc. It is also available for constant current equipment. It can be used in 5V DAC s to ensure the overall SN ratio and purity of the sound by eliminating noise from upstream of the signal.
* The PT140EI you purchased will be shipped from the manufacturer according to the audio equipment you plan to use. If the error range is 10%, it will be a fine setting. Switching power supplies are generally limited to 5V, 12V, 15V, and 24V, but in that range the output is provided as fixed according to the input voltage. The input voltage is between 100v and 120v, but all output DC voltage is fixed.

DC cable using NEGLEX OFC conductor
Mogami electric wire Using mogami shield wire using NEGLEX OFC conductor, DC cable that delivers pure power to amplifier and DAC is available.
By using the internal two-core plus and the external shield wire for GND, the coaxial structure became more and more external noise.
