1.1 Input Voltage Range
¡Input voltage range of the power supplies is from AC85V to
AC264V or DC (please see SPECIFICATIONS for details).
¡If input value doesn’t fall within above range, a unit may not oper-
ate in accordance with specications and/or start hunting or oper-
ate 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 specication. Please contact us.
¡To comply with safety standards,input voltage range is shown in
Table 1.1.

*Please avoid using continuously for more than 1 second under
above conditions. Doing so may cause a failure.
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 one
that can withstand an input inrush current.
¿ KHEA30F/60F/90F/120F,
KHNA30F/60F/90F/120F
¡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.
¿
KHEA240F/480F, KHNA240F/480F
¡Thyristor technique (KHEA/KHNA240F) and power relay tech-
nique (KHEA/KHNA480F) is used in the inrush current limiting
circuit.
1 Functions ¡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 cur-
rent and secondary inrush current will be generated.
1.3 Overcurrent Protection
¿ KHEA30F/60F/90F, KHNA30F/60F/90F
¡A overcurrent protection circuit is built-in and activated over 105%
of the rated current. A unit automatically recovers when a fault
condition is removed. Please do not use a unit in short circuit and/
or under an overcurrent condition.
¡Hiccup Operation Mode (except KHEA/KHNA90F)
When the overcurrent protection circuit is activated and the output
voltage drops to a certain extent, the output becomes hiccup 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 0.5 second, the output
voltage may shut down. To recover the output voltage, remove a
condition that is causing an overcurrent, shut down the input volt-
age, wait more than 3 minutes and turn on the AC input again.
¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡An overcurrent protection circuit is built-in and activated over
101% of the peak current. A unit automatically recovers when a
fault condition is removed. Please do not use a unit in short cir-
cuit and/or under an overcurrent condition.
¡Hiccup Operation Mode
When the overcurrent protection circuit is activated and the out-
putvoltage drops to a certain extent, the output becomes hiccup
so that the average current will also decrease.
1.4 Peakcurrent Protection
¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡Peakcurrent protection is built-in (refer to Instruction Manual 3 for
Peak loading).
If this function comes into effect, the output is shut down.
A few seconds later, A unit automatically recovers.
But if the overcurrent condition has not been released, the output
will stop again (hiccup Operation Mode).
*The recovery time varies depending on input voltage and load
condition.
1.5 Overvoltage Protection
¿ KHEA30F/60F/90F, KHNA30F/60F/90F
¡An overvoltage protection circuit is built-in. If the overvoltage pro-
tection circuit is activated, shut down the input voltage, wait more
than 3 minutes and turn on the AC input again to recover the out-
put voltage. Recovery time varies depending on such factors as
input voltage value at the time of the operation.
¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡An overvoltage protection circuit is built-in.
AC-DC Power Supplies DIN Rail Type Instruction Manual
KH-22 June 29, 2020

A 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 malfunc-
tion 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.
1.6 Thermal Protection
¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡A thermal protection circuit is built-in.
The thermal protection circuit may be activated under the follow-
ing conditions and shut down the output.
1
When a temperature continue to exceed the values determined
by the derating curve.
2
When a current exceeding the rated current is applied.
3When convection stops.
4When peak load is applied in conditions other than those shown
in Section 3.
A unit automatically recovers when the fault condition is removed.
1.7 Output Ripple and Ripple Noise

ment, measuring method g 1.1 is recommended.

1.8 Remote ON/OFF
¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡You can reduce the standby power by Remote ON/OFF.
To do so, connect an external DC power supply and apply a volt-
age to a remote ON/OFF connector.

*1 If the output of an external power supply is within the range of
4.5 - 29.5V, you do not need a current limiting resistor R. If the
output exceeds 29.5V, however, please connect the current limit-
ing resistor R.
To calculate a current limiting resistance value, please use the fol-
lowing equation.

¡Please wire carefully. If you wire wrongly, the internal components
of a unit may be damaged.
¡Remote ON/OFF circuits (+RC and -RC) are isolated from input,
output and PE.
¡Restart time is 750 ms max .
1.9 Output Voltage Adjustment Range
¡To increase an output voltage, turn a built-in potentiometer clock-
wise. To decrease the output voltage, turn it counterclockwise.
1.10 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 gen-
erate a voltage a few times higher than the applied voltage.
¡When you test a unit for isolation between the output and the
DC_OK, short all terminals of DC_OK.
1.11 Signal Output

¿
KHEA120F/240F/480F, KHNA120F/240F/480F
¡Functions of LED indicators and signal output in the form of relay
contact are shown below. Checking the presence/absence of volt-
age at the output terminal of a power supply is possible.

*DC_OK signal (relay contact) is built in KHEA 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.

rent in series operation should be lower than the rated current of a
power supply with the lowest rated current among the power sup-
plies that are serially connected. Please make sure that no current
exceeding the rated current ows into a power supply.

¡While turning on the electricity, and for a while after turning off,
please don’t touch the inside of a power supply because there are
some hot parts in that.
¡When a mass capacitor is connected with the output terminal
(load side), the output might become the stop or an unstable oper-
ation. Please contact us for details when you connect the capaci-
tor.
