APC 8953 LOAD RATINGS AND CALCULATIONS

[Anonymous user]

Hello!

I´am brand new at this group and I am facing some difficulties I will be pleased if someone could help me. I need to evaluate a allocation of a new one dell POWEREDGE R-530 (Power consunption = 750W) on a rack which is supplied by 01 (one) APC 8953 PDU on each side and also has been installed some other server in such an load charge of 3.0A@214V on the lef side and 1.3 A@214V on the right side.

I am not familiar with power calculations and I would be pleased if someone could teach me how to calculate if the PDU´s can supply the requested load so It will be possible for me to perform further calculations when new servers come to be allocated.

Thanks in advance,

Hi Ivan,

I am not quite sure I understand the question as you've asked it. I also think you made a typo on the model of the PDU - could you recheck? We have several models that begin with AP895.. AP8958, AP8959, AP8958NA3, etc.  Once you know which one you have, we can check the documentation on the maximum load capacity it can handle. Is that what you need - the maximum load rating capacity of your PDU?

We also have this general information too on the accuracy of the current monitor which being unclear on what you needed to check, I wanted to give you just in case as a starting point: http://www.schneider-electric.us/en/faqs/FA156074

Hi Angela! 

Thanks for help. The PDU model is the APC 8953.

What I need exactly is the formulas for calculations of electric parameters (power/current/voltage, etc) to calculate each load increase when a new server is installed in order to accept a new server collocation on the rack and can evaluate the remaining power supply for further server collocations availability. The PDU maximum load capacity is also a useful information.

Sorry but I am an old electrical engineer and I really do not remember how to calculate the 3ph power and load.

Thanks once more.

Hope to hear from you soon.

Hi Ivan,

OK, I am not sure why AP8953 is not coming up on our website but its specifications are located here -> http://www.apcmedia.com/salestools/JKUR-7RBT76/JKUR-7RBT76_R0_EN.pdf

Check here for the calculations you may be talking about? http://www.apc.com/us/en/faqs/FA156194 I am not a power expert either but I think that is what you may be interested? We have calculations listed for single and 3 phase power PDUs.
