Hertz (Hz): A unit of frequency equal to one cycle per second.
Joules: A rating commonly used to indicate energy storage, or the amount of electrical surge that can be absorbed by a surge suppressing device. The higher the joule rating, the more energy absorbed.
Normal Isolated Mode: The default power transformer configuration that cuts noise with Clean Power Stage 5 filtering and breaks the connection with ground. Effective at ridding many A/V systems of hum, buzz, vertical
or horizontal lines on a projector, CRT or Plasma display.
Peak Current: The maximum current flow a device can handle without breaking down or shortening its published life specifications.
Power: The energy dissipated into a circuit or component.
Power Line: Two- or
RFI: Radio Frequency Interference. Distortion that propagates into and interferes with the operation of electronic equipment in the radio frequency range.
Spike: An abrupt power line transient that distorts the AC waveform.
Surge: A large, sudden change of voltage or current, usually caused by a shorted or opened circuit.
Surge Protector: A device that protects components from high voltage peaks and transients.
Transient: A momentary surge on a signal or power line that distorts the AC waveform.
UL: Underwriters’ Laboratories. An organization that establishes the safety standards of various types of equipment.
Video Noise: Electrical disturbances caused by a source extraneous to the signal in the
Volt (V): Unit of measurement for the electromotive force. One volt is equivalent to the energy required to produce a current of one ampere through a resistance of one ohm.
Voltage: Electrical pressure, or the force required to flow current through an electrical conductor.
Voltage Rating: The maximum voltage which an electrical device or component can sustain without breaking down.
