What's behind YOUR music?
Today's equipment has the potential to deliver more
fidelity, more clarity, better music. Belleson Superpower
regulators let your audiophile system deliver its full potential
with
the stiffest, smoothest, quietest voltage
regulator ever, to deliver music pure,
transparent and brilliant.
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 them 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

We have a new Transformer Calculator
to calculate the minimum Vrms voltage of a transformer for your
Superpower based supplies.
Short Circuit? No Problem!
Belleson is introducing another first—the first super regulator with short circuit protection.
The SPL line of regulators will not go up in smoke if the output is momentarily connected to ground.
What's so novel about that? One of the primary benefits of the super regulator is its low
output impedance. Standard short circuit current limit circuits place a resistor in the output circuit
to sense current. Superpower uses a proprietary current limiter that does not add any
resistance to the output, you still have a bipolar emitter connected directly to the load.
See Super protection for a full discussion of this subject.
Note that SPL does not have a thermal limiter, so a long duration short can still destroy
an SPL device. The higher Vout, the less time it can survive a short circuit, for example a 30V SPL
can only survive a 1/2 second short to ground. This is due to the 60W+ power dissipation from the 2A
output current.
MORE POWER! LOWER DROPOUT!
We didn't add dilithium crystals to Superpower, but it's almost as good. The SPJ Superpower
is specified for output current to 2 amps, and with proper heat sinking can deliver more. Drop out
voltage is less than 1V too! SPJ also dissipates heat much better than the standard design.
See data sheet (PDF) for full specifications.
The standard SP provides up to 500mA with 2V drop out and has a lower price.
