Power Supply Parameters Three major power supply (Figure 1) architectures are defined for any engineer: 1.Linear Regulators. 2.Pulse width modulated switching (PWM). 3.High resonant technology switching. Vin(low), Vin(high) – minimum and maximum allowed input voltages, hence input voltage range. Iin(max) – maximum average input current. Outputs: Vout(min), Vout(max) – minimum and maximum allowed output voltages,

NORWOOD, Mass. (PRWEB) September 19, 2008 “Industrial amplifiers are subject to fault voltages from a variety of sources, including electro-magnetic interference, damaged cabling, lightning strikes and other disturbances on the power grid, incorrect hookups to other system components and power-line surges when power to the system is restored after routine service or equipment upgrades,” said
