PS5R-V Switching Power Supplies
Mounting on DIN Rails
1. Use a 35mm-wide DIN rail.
2. Fasten the DIN rail to a mounting plate using screws.
3. Place the PS5R-V on the DIN rail as shown with input termi-
nal side up (), and press the PS5R-V towards the DIN rail
(). Make sure that the PS5R-V is installed rmly.
4. Use BNL6 mounting clips for fastening the PS5R-V on the
DIN rail. Use of BNL8 mounting clips is recommended when
excessive vibration or shock is anticipated. Do not use the
PS5R-V when it is subject to vibration constantly.
Removal
•Insert a at screwdriver into the slot in the clamp, and pull out
the clamp until it clicks (). The lock mechanism is released
and the PS5R-V can be removed (). When mounting the
PS5R-V again, push in the latch rst.
Notes for installation
•Do not close the top and bottom openings of the PS5R-V to
allow for heat radiation by convection.
•Maintain a minimum of 10 mm clearance around the PS5R-V,
except for the top and bottom openings.
•When mounting multiple PS5R-V switching power supplies
side by side, maintain a minimum of 10 mm clearance. Ob-
serve the derating curves in consideration of the ambient
temperature.
10mm minimum
•When the derating voltage may exceed the recommended
value, provide forced air-cooling.
•Make sure to wire the ground terminal correctly.
•For wiring, use wires of heat resistance of 60C or higher
(PS5R-VB: 80C or higher). Use copper wire of the following
sizes, according to the rated current.
Terminal Wire Size (allowable current) Wire Type
Input AWG18 to 14 Copper
Solid/Stranded
Output AWG18 to 14
(AWG18: 7A, AWG16: 10A, AWG14: 15A)
Cross-sectional area
AWG18: 0.82mm2, AWG16: 1.31mm2, AWG14: 2.0mm2
Note: Wires of the above size must be used to comply with
UL508, CSA C22.2 No. 107.1.

•Recommended tightening torque of the input and output ter-
minals is 1.0 to 1.3 N·m (0.8 N·m for UL).
Safety Precautions
Operating Instructions
Mount the PS5R-V in an enclosure. Do not use the PS5R-V
alone as an Electric Facilities for General Use.
Use the PS5R-V for electric facilities for business use only.
•Do not use switching power supplies with electric equipment
whose malfunction or inadvertent operation may damage the hu-
man body or life directly.
•Make sure that the input voltage and output current do not ex-
ceed the ratings. If the input voltage and output current exceed
the ratings, electric shock, re, or malfunction may occur.
•Do not touch the terminals of the switching power supply while
input voltage is applied, otherwise electric shock may occur.
•Provide the nal product with protection against malfunction or
damage that may be caused by malfunction of the switching
power supply.
•Operating temperatures should not exceed the ratings. Be sure to
note the derating characteristics. If the operating temperature ex-
ceeds the ratings, electric shock, re, or malfunction may occur.
•Blown fuses indicate that the internal circuits are damaged. Con-
tact IDEC for repair. Do not just replace the fuse and reoperate,
otherwise electric shock, re, or malfunction may occur.
•Do not use the switching power supplies to charge rechargeable
batteries.
•Do not overload or short-circuit the switching power supply for
a long period of time, otherwise the internal elements may be
damaged.
•Do not disassemble, repair, or modify the power supplies, other-
wise the high voltage internal part may cause electric shock, re,
or malfunction.
•The fuse inside the PS5R-V switching power supply is for AC
input. Use a DC fuse for DC input.

Installing PS9Z-6R2F Side-mount Panel
Mounting Bracket
Install the bracket on the switching power supply using four
M3 × 6 countersunk screws supplied with the bracket.
Adjustment of Output Voltage
The output voltage can be adjusted within ±10% of the rated
output voltage (PS5R-VE: ±5%) by using the VR.ADJ control
on the front. Turning the VR.ADJ clockwise increases the out-
put voltage. Turning the VR.ADJ counterclockwise decreases
the output voltage.
Overcurrent Protection
The output voltage drops automatically when an overcurrent
ows due to an overload or short circuit. Normal voltage is
automatically restored when the load returns to normal condi-
tions.
Insulation/Dielectric Test
When performing an insulation/dielectric test, short-circuit the
input (between L and N) and output (between +V and –V). Do
not apply or interrupt the voltage quickly, otherwise surge volt-
ages may be generated and the PS5R-V may be damaged.
Notes for Operation
•Output interruption may indicate blown fuses. Contact IDEC.
•The PS5R-V switching power supply contains an internal fuse
for AC input. When using with DC input, install an external
fuse for DC input. To avoid blown fuses, select a fuse in con-
sideration of the rated current of the internal fuse.
Rated Current of Internal Fuses
Part No. Internal Fuse
Rated Current
PS5R-VB/VC 2A
PS5R-VD/VE/VF 4A
PS5R-VG 6.3A
•Avoid overload and short-circuit for a long period of time,
otherwise the internal elements may be damaged.
•DC input operation is not subject to safety standards.
Rust and Scratches on Metal parts
Hot-dip galvanized steel and bonderized steel are used for the
PS5R-V. Rust on the edge and scratches on the surfaces may
be developed depending on the storage condition, but the
performance of the PS5R-V is not affected.
Noise
Small acoustic noise inside the PS5R-V may be heard de-
pending on the input voltage and load, but the performance of
the PS5R-V is not affected.

Series Operation
The following series operation is allowed. In (b) series opera-
tion, connect Schottky barrier diodes. Choose (a) series opera-
tion when using the PS5R-V as positive and negative output
power supply. Insert a Shottky barrier diode for loads such
as operational amplier where outputs of two power supplies
may be connected in series (Load 3). Select a Schottky diode
in consideration of the rated current.

Parallel Operation
Parallel operation is not possible to increase the output capac-
ity, because the internal elements and load may be damaged.
Backup Operation
Backup operation is a connection method of two switch-
ing power supplies in parallel for emergency. Normally one
switching power supply has a sufcient output. If one switch-
ing power supply fails, another one operates to continue the
output. Make sure that the sum of power consumption by load
and diode is not greater than the rated wattage (rated voltage
× rated current) of one switching power supply.
