Introduction
Thank you for your purchase of the PS Audio UPC-HB Power Center.
The UPC-HB is designed to provide AC cleaning, isolation and complete protection from surges,
spikes and power line problems from the AC power line, as well as providing hum free operation for
products connected.
The UPC-HB is based on PS Audio’s unique Ultimate PowerCell™ and Humbuster™ technology.
Ultimate PowerCells combine an energy store and release system coupled with a low resistance
inductive cleaning element that provides cleaner, low impedance, non-restricting AC power to the
load. Ultimate PowerCells also provide noise isolation from equipment connected to them. Humbuster
technology eliminates DC on the AC line and reduces mechanical transformer hum in connected units.
The Humbuster will not typically reduce hum in the loudspeakers.
There is one Ultimate PowerCell in the UPC-HB and one Humbuster circuit. The Humbuster circuit is
power through the Ultimate Power Cell.
Surge and spike protection is provided by non-degrading multiple Tranzorbers backed up by high
current MOV’s. Tranzorbers eliminate 99% of all surges and spikes that occur on the line and these
Tranzorbers will continue to keep your equipment safe for many years to come. Unlike MOV’s,
Tranzorbers are non-degrading. In the unlikely event the surge or spike is large enough to potentially
damage the Tranzorbers in the UPC, protection circuitry within the UPC will engage the backup MOV’s
and disconnect your equipment from the power line. In this way, MOV’s are rarely used and then only
for backup purposes.
You can expect 100% safe operation for any connected equipment along with improved
performance.
Equipment connected to the Humbuster circuit should enjoy lower internal mechanical noise.
