HALCRO's UPFC creates no distortion or interference to the mains supply. Produces no troublesome mains current surges at 100 or 120Hz. Automatically operates at any mains voltage variation between 85V through to 270Vr.m.s. without the need for internal or external switches. Less than 100 parts per million mains hum and ripple on the amplifier power rails. Conventional power factor corrected power supplies over 200 watts are illegal in all EU countries since January 2002 due to a change in CE laws. Conventional power supplies will also produce audio problems. The HALCRO UPFC eliminates these problems as well: It switches at frequencies above 100kHz regardless of the mains voltage or power consumption, eliminating interference near the audio range. It requires no internal fan for cooling. The HALCRO power supply is housed in the lower of the two compartments and is heavily shielded from the amplifier circuitry. It is protected from mains transients, and the inputs and outputs have high levels of filtering, both common and series-mode to cut out R.F. interference and mains spikes and glitches.
