input range of 90–288 VAC is designed to be used from AC power available from stadium and outdoor power sources. The single output is customer selectable between 32V and 48VDC at 200W.
Jake Moir, Managing Director of Gresham Power, comments; “With the growth of outside broadcast, music and similar events we have found a growing market for a power supply with a wide input range. In the USA such events frequently take power from street lighting which may be up to 277 volts and which would stress conventional switch mode power supplies reducing their reliability or in the worst case causing them to fail immediately. Our new 200 watt power supply is not only designed to accommodate a very wide input range but also allows the user to select their required output voltage, simplifying the end system design process and reducing inventory.”
