PS5R-V Switching Power Supplies
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.

Diode's current must be more than double the PS5R-V's
output current. Take heat dissipation into consideration.
Operating Instructions
Warranty
Warranty
IDEC warrantees the PS5R-V switching power supplies for a
period of ve 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 5.
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 conse-
quential, contingent or incidental damages. Warranty does not
apply if the PS5R-V switching power supply was subject to:
1. Inappropriate handling, or operation beyond the specica-
tions.
2. Modication or repair by other than IDEC.
3. Failure caused by other than the PS5R-V switching power
supply.
4. Failure caused by natural disasters.
