Description
IWISTAO 120W Linear Regulated DC Power Supply 5V to 24V MOSFET Design
Model No: WHFLPS-DC12TO24
The IWISTAO 120W Linear Regulated Power Supply is a high-performance DC power source designed for audiophiles, engineers, and system integrators who demand ultra-low noise and stable voltage output.
Built around a high-quality toroidal transformer, this unit employs LM317 and TL431 as reference transistors, combined with a Toshiba 2SA1943 high-power transistor for current amplification. The result is exceptional voltage precision, superior thermal stability, and significantly lower ripple compared to standard switching power supplies.
This makes it ideal for powering sensitive audio and digital equipment such as DACs, HDD enclosures, NAS systems, routers, and similar devices that benefit from a clean and stable DC source.
Note: This is a linear power supply. A slight temperature rise during high-current operation is normal and within the safe working range.
