Downloaded byRadioAmateur.EUYAESU FP-757GXSWITCHING POWER SUPPLYThe FP-757GX is a solid state switching supply designed to match the FT-757GX All Mode HFTransceiver.The extremely small size and light weight are the obvious advantages of the latestswitching supply technology,which eliminates the need for a bulky power transformer.Gone too isthe heat caused by power losses in the transformer,resulting in extremely high efficiency and tightregulation over wide ranges of AC input voltage and DC output current demands.SPECIFICATIONSInput Voltage:85 to 132V or 170 to 264 VAC (selectable)Output Voltage:13.5 VDC at rated load (approx.15 V at 1 A)Load Rating:1 A to 20A (50%duty cycle at 20 A less than 30 seconds)Ripple:600mV p-p at 20AOperating Temperature Range:0°Cto40°CCase Size (WHD):238×39×238mWeight:approx.2 kg (4.4 1b)INSTALLATIONAlthough the high efficiency of the FP-757GX allows it to run cool even at high current,care must betaken to avoid overheating in conditions of very high humidity and/or ambient air temperature.Make sure that adequate space is provided for the free flow of air around the sides of the FP-757GX atall times.INTERCONNECTIONSBefore connecting the FP-757GX,check that the voltage range on the label on the rear panel near theAC power jack includes your local AC line voltage.If not,perform the AC Voltage Change procedurebelow before connecting power.Connect the DC 13.5 V cable from the FP-757GX to the DC 13.5 Vjack on the rear panel of the FT-757GX.Check to make sure that all POWER switches are OFF,andthen connect the AC cord to the wall outlet.FT-757GX/SXDC 13.5VFP-757GXo回oAC CORD
