AC-DC Power Supplies Enclosed TypeInstruction Manual1 Functions1.1 Input Voltage Range!The input voltage range is AC180-528V (three-phase).!In cases that conform with safety standard, input voltage range isAC200-AC480V (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 three wiresto input terminal (L1, L2, L3), except neutral wire.180~528VAC180~528VACDelta connectionStar connection!If the wrong input or single phase input is applied, the unit willnot operate properly and/or may be damaged. If the input is thesquare wave like a UPS and inverters, please contact us.!A unit complies with IEC61000-6-2 and SEMI F47 input voltagedip.1.2 Inrush Current Limiting!A unit has the built-in inrush current limiting circuit.!If a switch needs to be installed on the input side, please selectone that can withstand an input inrush current.!Thermistor and IGBT are used in the inrush current limiting circuit.When AC input is removed and reapplied in a short period of time,the inrush current limiting circuit might not work. Please haveenough intervals so that a power supply cools down before beingturned on. And, the primary and the secondary inrush current willfl o w.1.3 Overcurrent Protection!A unit has the built-in overcurrent protection circuit which will activateat over 105% of the rated current. A unit automatically recoverswhen a fault condition is removed.Please do not use a unit in short circuit and/or under an overcurrentcondition.!Hiccup modeWhen the overcurrent protection circuit is activated and the outputvoltage drops to a certain extent, the output becomes hiccupmode so that the average current will also decrease.Note :!Please avoid applying a voltage exceeding the rated voltage to anoutput terminal. It may cause a power supply to malfunction or fail.If it cannot be avoided like motor load and so on, please contact us.1.5 Thermal Protection!A unit has the built-in thermal protection circuit.When a current and a temperature continue to exceed the valuesdetermined by the derating curve, the thermal protection circuitmay be activated and shut down the output.!The output voltage recovers from the thermal protection by the followingactions.1) AC input is removed and reapplied after removing the overheatcause and cooling a unit.2) The output is turned off by the remote ON/OFF function andturned on after removing the overheat cause and cooling a unit.1.6 Output Voltage Adjustment Range!To increase an output voltage, turn the built-in potentiometerclockwise.To decrease the output voltage, turn it counterclockwise.!The output voltage can be adjusted by changing the voltage betweenthe terminal VTRM and the terminal COM on CN1/CN2.The output voltage can be decreased by drawing a current fromthe VTRM terminal. In this case, the output voltage value can becalculated by the formula 1 below. 1 is the formula for estimating.If the accurate number is necessary, please contact us.Please do not apply +5V or more or negative voltage betweenVTRM and COM.Please contact us for the detail of the output adjustment if needed.The voltage betweenOutput voltage =VTRM and COM2.5 [V]Xrated output voltage--- 1Table 1.1 Output voltage adjustment rangeModelOutput voltage adjustment range byVTRM terminal [V]HCA3500TF-4824.0 to 55.2HCA3500TF-6532.5 to 74.7* The output voltage should not be adjusted to lower voltage thanthe spec because it may be hiccup mode.1.4 Overvoltage Protection!When output voltage is increased and the overvoltage protectionactivates, the output voltage is shut down.!Output voltage recovers from overvoltage protection by shuttingdown the input voltage and waiting more than 3 minutes then turningon AC input again, or turning off the output voltage by remotecontrol.HCA-8
