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. Recommended tightening torque is 0.5 to 0.6N.m (should be in the center

positions)

Adjustment of Output Voltage

The output voltage can be adjusted within ±10% (VE: ±5%) of the rated output voltage by using

the VR.ADJ control on the front. Turning the VR.ADJ clockwise increases the output voltage.

Turning the VR.ADJ counterclockwise decreases the output voltage.

Overcurrent Protection

The output voltage drops automatically when an overcurrent flows due to an overload or short

circuit. Normal voltage is automatically restored when the load returns to normal conditions.

Insulation/Dielectric Test

When performing an insulation/dielectric test, short-circuit the input (between L and N) and out-

put (between +V and -V). Do not apply or interrupt the voltage quickly, otherwise surge voltages

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 DC

input, install an external fuse. To avoid blown fuses, select a fuse in consideration of the

rated current of the internal fuse.

• 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

Bonded metal parts 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 depending on the input voltage and load,

but the performance of the PS5R-V is not affected.

Series Operation

Series operation is allowed. Connect Schottky barrier diodes D as shown below. Select a

Schottky diode in consideration of the rated current. The diode’s reverse voltage must be higher

than the PS5R-V's output voltage.

Parallel Operation

Parallel operation is not possible to increase the output capacity, because

the internal elements and load may be damaged.

Backup Operation

Backup operation is a connection method of two switching power supplies in parallel for

emergency. Normally one switching power supply has a sufficient output. If one switching power

supply fails, another one operates to continue the output. Make sure that the sum of power con-

sumption by load and diode is not greater than the rated wattage (rated voltage × rated current)

of one switching power supply.

WARRANTY

IDEC warranties the PS5R-V switching power supply for a period of five years from the date of

shipment.

Scope

IDEC agrees to repair or replace the PS5R-V switching power supply if the product has been oper-

ated under the following conditions. The maximum value of output capacity is within the range

shown in “Operating Temperature vs.

Output Current on page 3.

1. Average operating temperature (ambient temperature of switching power supply) is 40°C

maximum.

2. The load is 80% maximum.

3. Input voltage is the rated input voltage.

4. Standard mounting style

IDEC shall not be liable for other damages including consequential, contingent or incidental dam-

ages. Warranty does not apply if the PS5R-V switching power supply was subject to:

1. Inappropriate handling, or operation beyond specifications.

2. Modification or repair by other than IDEC.

3. Failure caused by other than the PS5R-V switching power supply.

4. Failure caused by natural disasters.
