System and Rectifier Selection

Follow these steps to select the correct system model, rectifier type and number of rectifiers
for your application:
What is the nominal ac supply voltage (120V or 208-240V)?
1
What is the total power requirement of the equipment to be connected to the
2
EPS2/EPS5?
Add up the power ratings of all equipment that will be powered from the
•
EPS2/EPS5. Look at the rating labels on the back of the routers, servers and other
equipment. Or refer to the equipment manufacturer's specifications. The power is
given in watts (W).
If you plan to add more equipment later then you may want to size the EPS2/EPS5
•
so that it can also supply this future requirement.
Up to 10 dc circuits can be connected to each EPS2/EPS5.
•
Select the EPS2/EPS5 system and rectifier type to suit your needs.
3
Use one of the selection charts below to select the correct system and rectifier type.
•
The number of rectifier modules shown in the charts includes one redundant
•
rectifier. This is an additional (hot-spare) rectifier for added security.
