Linear power supply with large hand-wound EI core transformer

Overwhelming margin and richness of expression

Description

PT140EI is aThe PT140EI is an over-spec linear transformer power supply that uses a large transformer carefully hand-wound one by one by Kennetn Wong, who is regarded as a master of transformers in Hong Kong's high-end DIY audio industry. It supports up to 4A in Max 4 ports total using the large EI hand-wound core transformer.

The PT140EI isprovides an overwhelming margin and richness of expression.

The 12-24V model is designed for use in amplifiers, DACs, and other devices used to amplify or convert music signals, so when used in devices such as switching hubs, HDDs, and routers used for network audio that constantly consume large amounts of current, the regulator When used with devices such as switching hubs, HDDs, routers, and other devices used for network audio that constantly consume large amounts of current, the heat generated by the regulator could cause output to stop.

In designing the 5-12V specification, the heat loss generated during voltage conversion in the regulator is reduced by installing dedicated taps for 12V and 5V on the secondary side of the transformer, and the allowable current is further improved by connecting two regulators in parallel. 5-12V specification is applicable to amplifiers, DACs, and network audio equipment, The 5-12V specification can be used for amplifiers, DACs, network audio equipment, etc. The 5-12V version can be used for amplifiers, DACs, and network audio equipment, etc. It can also be used for constant current devices, and when used with a 5V DAC, it can eliminate noise from the signal upstream to ensure the signal-to-noise ratio and sound purity of the entire system.

*The PT140EI you purchase will be shipped from the manufacturer matched to the audio equipment you plan to use. A margin of error of 10% is acceptable. Switching power supplies are generally available in 5V, 12V, 15V, and 24V ranges, and the output is fixed to the input voltage within these ranges. There are input voltages from 100v to 240v and so on, but all of them have a fixed output DC voltage.

DC cable using NEGLEX OFC conductor

We offer DC cables that use mogami's shielded wires with Mogami Electric Wire NEGLEX OFC conductors to deliver pure electric power directly to amplifiers and DACs.
By using the internal two-core conductor for positive and the external shielded wire for GND, the coaxial structure is even more resistant to external noise.
