Fourier theorem - Theorem stating that any non-sinusoidal periodic function (frequency f) may be represented as a sum of terms (series) made up of - n a sinusoidal term with frequency f, called the fundamental frequency, n sinusoidal terms with frequencies that are whole multiples of the fundamental frequency, (harmonics), n a possible DC component where n is a whole number. n = 1 corresponds to the fundamental, n > 1 to the harmonic of the nth order.
Bypass (automatic) - In the event of an overload or an unlikely UPS problem, your application is still powered, thanks to the automatic bypass module.
Energy - The output capability of a cell or battery, usually expressed in watt-hours.
Parallel - Term used to describe the interconnection of cells or batteries in which all the like terminals are connected together. Results in increased capacity.
Desorption - The opposite of absorption, whereby the material retained by a medium or another material is released.
Secure Waste Landfill - A landfill designed for disposal of normal household trash but which meets government standards designed to protect the environment.
Specific Energy - The ratio of the energy output of a cell or battery to its weight (Wh/kg). This term is used interchangeably with gravimetric energy density.
