Which Superpower?

All Belleson regulators use the same patented design to deliver super low noise, super high ripple rejection and blazing fast transient response. Which regulator you choose depends on the output voltage you need and how much power the regulator must dissipate. The following product descriptions can help you decide.

SPX Max Performance Superpower

  • Output load current to 10A
  • Positive and negative versions
  • 200W max power dissipation (with adequate cooling)

SPLV Low Voltage Superpower

The perfect regulator for low voltage technologies such as the ESS 9018 Sabre32 reference DAC.

  • Output voltage 1V to 2.5V, fixed only
  • positive and negative versions
  • 1A output current
  • <2.7V drop out

SPHV High Voltage Superpower

A tiny 4 pin TO-220 size regulator with output voltage from 5V to 450V. SPHV is perfect for powering tube amplifier stages with Superpower’s usual low noise, amazing ripple rejection and superb transient response.

  • Output voltage 5V to 450V
  • Positive only
  • 500mA output current
  • Variable output voltage with a single resistor
  • Great for tube/valve regulation
