AC-DC Power Supplies Enclosed TypeInstruction Manual1 Functions? FETA2500BA, 3000BA, 3000BC1.1 Input Voltage Range!Input voltage range of the power supplies is from AC170V toAC264V.!In cases that conform with safety standard, input voltage range isAC200-AC240V (50/60Hz).!If input value doesn’t fall within above range, a unit may not operatein accordance with specifi cations and/or start hunting or fail.If you need to apply a square waveform input voltage, which iscommonly used in UPS and inverters, please contact us.!When the input voltage changes suddenly, the output voltage accuracymight exceed the specifi cation. Please contact us.? FETA7000T!The input voltage range is AC170-264V (three-phase).!In cases that conform with safety standard, input voltage range isAC200-AC240V (50/60Hz).!The input phase line shall not be specifi ed, it can be connected toany input terminal.!In the case of three-phase four-wire system, connect the threewires to input terminal (L1, L2, L3), except ground wire.AC170 - 264VAC170 - 264VDelta connectionStar connection!If the wrong input or single phase input is applied, the unit will notoperate properly and/or may be damaged. If you need to apply asquare waveform input voltage, which is commonly used in UPSand inverters, please contact us.? FETA7000ST!The input voltage range is AC300-480V (three phase four wire).!For the safety standard test, the input voltage range is AC346-415V (three phase four wire, 50/60Hz).!The current fl owing through the neutral line (N phase) increaseswhen the AC input voltage is over AC456V three phase four wire(18Amax). This does not affect product quality. Please select asuitable wire gauge for the neutral line.L1!Three phase three wire input voltage is not supported.The neutral line must be connected.If the input voltage is not from three phase four wire connection orout of the specified range, the unit will not operate properly and/ormay be damaged. If you need to apply a square wave form inputvoltage, which is commonly used in UPS and inverters, pleasecontact us.1.2 Inrush Current Limiting!An inrush current limiting circuit is built-in.!If you need to use a switch on the input side, please select onethat can withstand an input inrush current.!Relay technique is used in the inrush current limiting circuit. Whenyou turn the power ON/OFF repeatedly within a short period oftime, please have enough intervals so that the inrush current limitingcircuit becomes operative.!When the switch of the input is turned on, the primary inrush currentand secondary inrush current will be generated because therelay technique is used for the inrush current limiting circuit.1.3 Overcurrent Protection!An overcurrent protection circuit is built-in and activated over105% of the rated current. A unit automatically recovers when afaulty condition is removed.Please do not use a unit in short circuit and/or under an overcurrentcondition.!Output voltage shuts down when the output voltage continuouslydrops due to overcurrent protection.!Output voltage recovers from overcurrent protection by shuttingdown the input voltage and waiting more than 10 seconds thenturning on AC input again, or turning off the output voltage by remotecontrol.1.4 Overvoltage Protection!When output voltage is increased to the overvoltage protectionvalue, output voltage is shut down.!Output voltage recovers from overvoltage protection by shuttingdown the input voltage and waiting more than 10 seconds thenturning on AC input again, or turning off the output voltage by remotecontrol.Note :!Please avoid applying a voltage exceeding the rated voltage to anoutput terminal. Doing so may cause a power supply to malfunctionor fail. If you cannot avoid doing so, for example, if you needto operate a motor, etc., please install an external diode on theoutput terminal to protect the unit.AC300 - 480VL2L3NThree phase four wire systemFETA-21
