Engineering Data
■Derating Curve
85 to 264 VAC or 110 to 350 VDC input
95 to 110 VDC input
Note: 1. The maximum ambient temperature for parallel operation is
45°C.
2. Parallel operation is not possible for an input of 95 to
110 VDC.
3. Although operation is possible in the (2) portion of the der-
ating curve, performance may be adversely affected, i.e.,
ripple noise may increase.
4. Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply in areas outside the derating
curve (i.e., the area shown by shading (1) in the above
graph).
Installation
Note: 1. Improper mounting will interfere with heat dissipation and
may occasionally result in deterioration or damage of inter-
nal parts. Use the standard mounting.
2. If there is a derating problem, use forced air-cooling. The
ambient temperature is specified for a point 50 mm below
the Power Supply.
■Overload Protection
The Power Supply is provided with an overload protection function
that protects the load and the power supply from possible damage by
overcurrent. When the output current rises above 105% min. of the
rated current, the protection function is triggered, decreasing the out-
put voltage. When the output current falls within the rated range, the
overload protection function is automatically cleared.
The values shown in the above diagrams are for reference only.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during op-
eration.
2. Internal parts may possibly deteriorate or be damaged if the
Power Supply is used for applications with frequent inrush
current or overloading at the load end. Do not use the Power
Supply for such applications.

■Precautions for Safe Use
The following precautions must be observed to ensure safety.
Mounting
•Mounting Direction
(Refer to Installation in Engineering Data on page 4.)
The internal parts may occasionally deteriorate or be broken due to
adverse heat dissipation depending on the mounting status. Do not
use the product in any way other than the standard mounting
direction.
•Mounting Space
Make sure that sufficient heat dissipation is provided when
installing the Power Supply to increase its long-term reliability.
Install the product in a location that allows a natural airflow to occur
around the Power Supply.
We recommend using End Plates (PFP-M) to secure the Power
Supply and to ensure that a space of at least 10 mm is maintained
between Power Supplies.
If the installation space above and below the Power Supply is less
than 50 mm, reduce the ambient temperature by 5°C. A minimum
space of 20 mm is required.
Note: 1. Convection of air
2. 50 mm min.
3. 10 mm min.
Wiring
•Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
•Use the following material for the wires to be connected to the
Power Supply to prevent smoking or ignition caused by abnormal
loads.
Use solid wires. Always attach pin crimp terminals when using
stranded wire. The stripping distance should be 6.5 mm.
Recommended Wire Type
•Do not apply more than 100 N force to the terminal block when
tightening the terminals.
•Be sure to remove the sheet covering the product before turning
ON the Power Supply and confirm that nothing is interfering with
heat dissipation.
Installation Environment
•Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration
source.
•Install the Power Supply well away from any sources of strong,
high-frequency noise.
Operating and Storage Conditions
•When installing the Power Supply, check for any signs that the
product or packaging has been struck. If internal parts have been
damaged, overvoltages may be output depending on the location of
the damage.
•Internal parts may occasionally deteriorate or be damaged. Store
the Power Supply at a temperature of -25 to 65°C and a humidity of
10% to 90%.
•Internal parts may occasionally deteriorate or be damaged. Do not
use the Power Supply in areas outside the derating curve (i.e., the
area shown by shading (1) in the graph on page 4). For UL508
Listing, the surrounding air temperature should be 40°C.
•Use the Power Supply at a humidity of 10% to 90%.
•Do not use the Power Supply in locations where condensation may
occur due to high humidity or where temperature changes are
severe.
•Do not use the Power Supply in locations subject to direct sunlight.
•Do not use the Power Supply in locations where liquids, foreign
matter, or corrosive gases may enter the interior of products.
Overload Protection
•Internal parts may possibly deteriorate or be damaged if a short-
circuited or overcurrent state continues during operation.
•Internal parts may possibly deteriorate or be damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Charging the Battery
•This product is not intended to function as a battery charger. If a
battery is to be connected as the load, mount an overcurrent
limiting circuit and an overvoltage protection circuit.

Output Voltage Adjuster
•The output voltage adjuster (V.ADJ) may possibly be damaged if it
is turned with unnecessary force. Do not turn the adjuster with
excessive force.
•After changing the setting of the adjuster, make sure that the output
capacity and output current do not exceed the rated output capacity
and rated output current.
•Output voltage is adjustable with the output voltage adjuster
(V.ADJ) on the front surface of the product from -10% to +15% of
the rated output voltage.
Do not increase the output voltage by more than 10% when
connected to a ZEN CPU Unit rated for 24 VDC.
DIN Track Mounting
To mount the Power Supply on a DIN track, hook portion (A) of the
Power Supply onto the track and press the Power Supply in direction
(B).
To dismount the Power Supply, pull down portion (C) with a flat-blade
screwdriver and pull out the Power Supply.
Series Operation
The Power Supply is not designed for series operation.
Output voltage (±)
Two Power Supplies can be used to create a ±output.
Note: When the load is an operational amplifier or other device
allowing series operation, astartup failure may occur when the
Power Supply is turned ON and internal circuits may be
damaged. Connect a diode as shown in the figure to prevent
this.
Use the following guidelines to select the diode.
Parallel Operation
Two Power Supplies can be operated in parallel.
Note: 1. For parallel operation,a maximum of two Power Supplies of
the same model can be connected.
2. For a DC input, parallel operation is possible only for 110 to
350 VDC.
3. ToensurethatthevoltagedropbetweeneachPowerSupply
and the load is the same, use the same wire length and
thickness to connect the load.
4. The load current will become imbalanced if the output
voltages are different, possibly causing a serious reduction
in the life of one of the Power Supplies. Adjust the output
voltages of the Power Supplies to the same value.
In Case there is No Output Voltage
The possible cause for no output voltage may be the presence of an
overload or overvoltage condition, or may be due to the functioning of
a latching protective device. The latching protection may operate if a
large amount of surge voltage such as a lightening surge occurs
while turning ON the Power Supply.
In case there is no output voltage, please check the following points
before contacting us:
•Check the overload protected status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
•Attempt to clear the latching protection function:
Turn the power supply OFF once, and leave it OFF for at least 1
minute. Then turn it on again to see if this clears the condition.
Insulation Resistance Test
When performing the test, be sure to short-circuit all the output
terminals to protect them from damage.
Dielectric Strength Test
•When a high voltage is applied between the input terminals and the
output terminals, electric energy builds up across the inductor L
and capacitor C of the internal noise filter. This energy may
generate a voltage surge when a high voltage is applied to the
Power Supply by a switch or timer, and as a result, the internal
parts of the Power Supply may possibly be damaged. To prevent
voltage impulses when testing, decrease the applied voltage using
the variable resistor on the dielectric strength testing equipment, or
apply the voltage so that it crosses the zero point when it rises or
falls.
•When performing the test, be sure to short-circuit all the output
terminals to protect them from damage.
