5 2 Functions 2. Input Voltage Range Input voltage range of the power supplies is from CV to C24V or DC (please see SPECIFICTIONS for details). To comply with safety standards, input voltage range is C- C24V (/Hz). If input value doesn t fall within above range, a unit may not operate in accordance with specifi cations and/or start hunting or operate protection circuit or fail. If you need to apply a square waveform input voltage, which is commonly used in UPS and inverters, please contact us. When the input voltage changes suddenly, the output voltage accuracy might exceed the specifi cation. Please contact us. EF/F/9F, NF/F/9F Operation stop voltage is set at a lower value than of a standard version (derating is needed). -Use Conditions Output EF,NF W EF,NF 2W E9F,N9F W Input CV or DCV Duty s/s *Please avoid using continuously for more than second under above conditions. Doing so may cause a failure. 2.2 Inrush Current Limiting n inrush current limiting circuit is built-in. If you need to use a switch on the input side, please select one that can withstand an input inrush current. EF/F/9F/2F, NF/F/9F/2F Thermistor is used in the inrush current limiting circuit. When you turn the power ON/OFF repeatedly within a short period of time, please have enough intervals so that a power supply cools down before being turned on. E24F/4F, N24F/4F Thyristor technique (E/N24F) and power relay technique (E/N4F) is used in the inrush current limiting circuit. When you turn the power ON/OFF repeatedly within a short period of time, please have enough intervals so that the inrush current limiting circuit becomes operative. When the switch of the input is turned on, the primary inrush current and secondary inrush current will be generated Overcurrent Protection EF/F/9F, NF/F/9F overcurrent protection circuit is built-in and activated at % of the rated current. unit automatically recovers when a fault condition is removed. Please do not use a unit in short circuit and/or under an overcurrent condition. Intermittent Operation Mode (except E/N9F) When the overcurrent protection circuit is activated and the output voltage drops to a certain extent, the output becomes intermittent so that the average current will also decrease. Output Voltage Shutdown If the output voltage drops according to the overcurrent protection circuit operating continuously for about. second, the output voltage may shut down. To recover the output voltage, remove a condition that is causing an overcurrent, shut down the input voltage, wait more than minutes and turn on the C input again. E2F/24F/4F, N2F/24F/4F n overcurrent protection circuit is built-in and activated at % of the peak current. unit automatically recovers when a fault condition is removed. Please do not use a unit in short circuit and/or under an overcurrent condition. Intermittent Operation Mode When the overcurrent protection circuit is activated and the outputvoltage drops to a certain extent, the output becomes intermittent so that the average current will also decrease. 2.4 Peakcurrent Protection E2F/24F/4F, N2F/24F/4F Peakcurrent protection is built-in (refer to for Peak loading). If this function comes into effect, the output is shut down. few seconds later, unit automatically recovers. ut if the overcurrent condition has not been released, the output will stop again (intermittent Operation Mode). *The recovery time varies depending on input voltage and load condition. 2. Overvoltage Protection EF/F/9F, NF/F/9F n overvoltage protection circuit is built-in. If the overvoltage protection circuit is activated, shut down the input voltage, wait more than minutes and turn on the C input again to recover the output voltage. Recovery time varies depending on such factors as input voltage value at the time of the operation. E2F/24F/4F, N2F/24F/4F n overvoltage protection circuit is built-in. unit automatically recovers when the fault condition is removed. Note : Please avoid applying a voltage exceeding the rated voltage to an output terminal. Doing so may cause a power supply to malfunction or fail. If you cannot avoid doing so, for example, if you need to operate a motor, etc., please install an external diode on the output terminal to protect the unit.

6 2. Thermal Protection E2F/24F/4F, N2F/24F/4F thermal protection circuit is built-in. The thermal protection circuit may be activated under the following conditions and shut down the output. When a temperature continue to exceed the values determined by the derating curve. 2 When a current exceeding the rated current is applied. When convection stops. 4 When peak load is applied in conditions other than those shown in Section. unit automatically recovers when the fault condition is removed. 2. Output ripple and ripple noise Output ripple noise may be infl uenced by measurement environment, measuring method fi g 2. is recommended. +Vout 2. Signal Output Functions of LED indicators and signal output (E series) E2F/24F/4F, N2F/24F/4F Functions of LED indicators and signal output in the form of relay contact are shown below. Checking the presence/absence of voltage at the output terminal of a power supply is possible. Table 2. Description of the signal output Signal Output Normal Output is decreasing DC_OK (LED: Green) ON OFF LRM (LED: Red) OFF ON DC_OK (Relay Contact) * Short Open *DC_OK signal (relay contact) is built in E series. This circuit is insulated from other circuits (input and output circuits). Caution on signal outputs : The timing of signals might be very depending on models, input and load conditions. Please make sure enough evaluation. -Vout C C2 + mm Load Peak Current Osiloscope/ Ripple noise meter w:2mhz Differential probe C:Film capacitor.mf C2:luminum electrolytic capacitor 22 mf Fig.2. Measuring method of Ripple and Ripple Noise 2. Remote ON/OFF E2F/24F/4F, N2F/24F/4F You can reduce the standby power by Remote ON/OFF. To do so, connect an external DC power supply and apply a voltage to a remote ON/OFF connector. Please contact us. E2F/24F/4F, N2F/24F/4F [] The units can generate the peak current under the following conditions. -t[sec -Ip[Rated peak current -Iave[Rated current -Duty[% (E2F/24F, N2F/24F) -Duty[2% * (E4F, N4F) * In case of mounting orientation (C), duty is less than %. t -Duty= X [%] t+t2 2.9 Output Voltage djustment Range To increase an output voltage, turn a built-in potentiometer clockwise. To decrease the output voltage, turn it counterclockwise. Output current Ip:Peak current Iave:verage current 2. Isolation When you run a Hi-Pot test as receiving inspection, gradually increase the voltage to start. When you shut down, decrease the voltage gradually by using a dial. Please avoid a Hi-Pot tester with a timer because, when the timer is turned ON or OFF, it may generate a voltage a few times higher than the applied voltage. t t2 Fig.. Peak current -

The output current in series operation should be lower than the rated current of a power supply with the lowest rated current among the power supplies that are serially connected.
