Alpha-Core Inc. balanced symmetrical power supply specifically designed to eliminate the noise and hum caused by unbalanced AC power lines.

The Alpha-Core BP30 power system was designed by the inventor, Dick Sequerra and is built around a unique balanced and shielded isolation transformer design. Due to the exact degree of balance, common mode noise and reactive components are reduced by at least 60 dB.

The Alpha-Core BP30 Power Supply can handle a continuous power of 1,000 W (8.4A) with input and output voltages of 120V for 60 Hz operation. A 240V, 60 Hz version is also available. There are four duplex grounded receptacles providing eight separate outlets. There is a 15A time-delay fuse.

The transformer uses a toroidal core construction, known for its low losses, low heat and low electro-magnetic interference (EMI), compared to conventional, stacked lamination type. The transformer design includes a static shield between primary and secondary windings to reduce the capacitive coupling and a built-in thermal cut-off, activated at 105 degrees Celsius. When operating continuously at full power, the temperature increase is a maximum of 85 degrees Celsius, well below the limit of 105 degrees Celsius for a class A transformer as required by UL standard UL506.

The choice of a toroidal transformer also allows a low profile enclosure. The standard design uses black anodized aluminum and measures 14.5" (368 mm) x 9.0" (228 mm) x 3.5" (89 mm) L x W x H, weighingy 26 lbs.(11.8 Kg). 

Unbalanced AC power contains noise and hum generated by every electrical device connected to the power line. The problem is caused not only by fluorescent lighting, light dimmers, air conditioners, refrigerators and other appliances, but also audio and video equipment.

Since the mid-1960s, commercial users such as motion film studios, video studios, audio recording studios, semiconductor manufacturers, as well as many military users have installed balanced isolation transformers, a concept developed by Bell Labs, to remove undesirable noise. For the first time, a balanced transformer is now within reach of anyone whose work requires noise-free operation of equipment.

For those with home theaters as well as discerning audiophiles, installing the Alpha-Core BP30 Power Supply can be the solution to eliminate power line noise. - POWER QUALITY MAGAZINE ARCHIVE
