Output phases on SURT10000XLI

[Anonymous user]

I have an APC Smart-UPS RT 10000 RM XL here, set up with 3 phase input. There are 4 IEC C13 and 4 C19 outputs. I want to know what the phases of these outputs are, relative to the 3 phases of the input.

I've looked through the web interface to the management processor, the user manual, technical specifications document, the physical system's markings, the APC website, knowledge base, and this forum - and can't find anything to tell me this information. Can any of the knowledgeable gurus here tell me, please?

i checked on this:

The unit is 3ph input and 1ph output, so all of the outlets are on the same phase. In bypass mode it will pull from Phase 1, which is why we spec a max draw on L1 of 50 amps when in bypass and 15amps when online. This is noted on the input wiring chart in the users manual (Page 2).

You can find the manual here: http://www.apcmedia.com/salestools/ASTE-6Z8LVK_R7_EN.pdf (which i know you maybe referenced).

Thanks. Does this mean that all of the outputs are in phase with the phase 1 input?

Thanks Battman for your input.

In your opinion, if a phase goes down will the UPS continue providing power from the grid or it will switch to battery backup.

Regards.

Input Power draw should be pretty close to the same on all three phases... I haven't seen the block diagram but there may be slightly more current drawn on one phase if there are control or management power circuits/modules using phase to neutral voltage instead of phase to phase.

I would like to know this also. Will it balance the power draw on all 3 phases?

This is a True Online (double conversion) UPS, meaning that the output is derived entirely separate and with separate phasing, from the input. The manual states however that "Whenever Possible, Output Frequency tracks Input Frequency".

Pretty sure that loss of a phase would be seen as an "outage event" and the UPS would switch to battery. Schneider forum admins would need to confirm...

Yes, if one phase is lost, UPS will go to battery.
