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 inter-

nal elements and load may be damaged.

Backup Operation

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

gency. 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 cur-

rent) of one switching power supply.

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

into consideration.

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

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.
