• Online UPs types are better than line interactive ones in terms of power regulation. Online UPS's have outstanding perfomance over poor power conditions such as rural areas and generator power.
• Many users, especially in places where power conditions are monstly stable and reliable, do not mind whether they use online or line-interactive designs. They look at other features such as runtime, power delivery, communications, size and other factors.

How does a UPS with higher power factor benefit users?

• UPS is rated both in VA and Watts. Exceeding the specified VA or Watts will cause the UPS to overload. 
• Modern servers and networking devices are equipped with Power Factor Corrected (PFC) power supply, whose pf is as high as 0.98. It means if power supply is rated at 100VA, it is also rated at 98W. 
• UPS’s with 1000VA/900Watts can support nine (9) of such devices. UPS’s with 1000VA/700Watts can only support seven (7) of such devices.

Can Liebert PSI have additional USB or RS232 ports?

• No. PSI has one (1) USB, one (1) contact closure, one (1) remote power off, and one (1) Liebert Intellislot out-of-box. There is no optional card with ports.

Is Liebert IS-WEBCARD compatible with Liebert PSI?

• Liebert PSI uses a new webcard, IS-WEBRT3, which is totally different from ISWEBCARD used by GXT2/GXT3. They are NOT interchangeable.

Can a Micropod for Liebert GXT2 be use with Liebert PSI?

• A Micropod is useful when there is UPS fault and it needs to replace UPS.
• Micropod can be used with Liebert PSI as far as electrical bypass is concerned. However, a Micropod needs to be rack mounted. It does not mechanically fit at the back of a Liebert PSI UPS.

What is the warranty period of Liebert PSI?

• Standard micro UPS warranty (usually 2 years) applies
