Push in the latch to LOCK position.

Ensure that the panel mounting bracket is locked by the latch.

Adjustment of Output Voltage

The output voltage can be adjusted within ±10% 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.

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.

Rated Current of Internal Fuses

	Part Number	Internal Fuse
		Rated Current
	PS5R-VB/VC	2A
	PS5R-VD/VF	4A

•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.

OPERATING INSTRUCTIONS

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.

			(a)			(b)

Parallel Operation

Parallel operation is not possible to increase the output capacity, because the internal elements and load may be damaged.

WARRANTY

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 operated 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

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 consumption by load and diode is not greater than the rated wattage (rated voltage × rated current) of one switching power supply.

Select a diode in consideration of:

Diode's current must be more than double the PS5R-V's output current. Take heat dissipation into consideration.

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