SPX, the champion in voltage regulation
Well into our second decade supplying the highest performance voltage regulators, we at Belleson are glad to continue providing products to improve your audio systems and more.
Belleson Superpower voltage regulators are available from 1V to 100V, with current to 10A. They are used as linear regulators on raw linear supplies and to clean up digital switching noise from switched mode power supplies. Our patented design delivers the highest available performance for critical regulation parameters such as noise, ripple rejection, dynamic transient response, output impedance and load regulation. They are used in thousands of DIY enhancements across the world, and by multiple audio equipment manufacturers making some of the world's finest audio reproduction systems.

Belleson has the highest performance voltage regulators in the industry. You can have a super high performance regulator for your system, whatever voltage or current it requires!
- SPX 3.3V to 30V @ 3A Vout variable 5V to 30V!
- SPHP 3.3V to 100V @ 10A 1000 Watts!
- SPLV 1.2V to 2.5V @ 2A
What's so super?
Belleson combined two great ideas into an amazing symbiosis to create the latest advancement in super regulators. Bootstrap powered by its own clean and quiet output voltage, the Superpower has amazing line and load regulation, low noise, low drop-out voltage, low output impedance and super fast dynamic performance.
Superpower can replace voltage regulators in your audio systems and give you the jaw-dropping performance you desire, with
- better overall performance than anything available
- a standard TO-220 footprint of monolithic regulators
- more current than any other aftermarket regulator
