The GSP750PS12-EF from XP Power is an Isolated AC-DC Converter that steps down an AC input voltage of 80-264 V to a DC output voltage of 12-48 V. This converter delivers an output power of 750 W and has an efficiency of up to 90%. It intelligently controls the cooling fans to reduce acoustic noise generated within the system and hence eliminates the need for forced air cooling, thereby allowing the fans to be switched off to provide silent running operation during periods of lower system loading or system standby conditions. This AC-DC converter is available in a chassis-mount package that measures 10.0 x 4.0 x 1.65 inches and is ideal for IT/industrial and medical applications.
