PS5R-V Switching Power Supplies
Series Operation
The following series operation is allowed. In (b) series operation, connect
Schottky barrier diodes. Choose (a) series operation 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 consider-
ation of the rated current.

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
sufcient 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.
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 Tempera-
ture 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 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 the specications.
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.
