UPS 120Vac

This was originally posted on APC forums on 5/27/2009


Hi,

Does [SUVTP10KF3B4|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SUVTP10KF3B4&tab=models&total_watts=...] have as an output voltage 120Vac? I know its output is 3 phase 208Vac, but I want to be sure if the voltage PH-N is 120Vac because the installation and operation manual don't say it.

And what should I need if I want to install a Symmetra LX @ 120Vac ( [SYA12K16P|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SYA12K16P&total_watts=500] ) and if I have as an input 3 phase 220Vac (3 PH and GND, no N, voltage PH-PH 220Vac), maybe an isolation transformer with what specifications?

HA

the [tech specs|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SUVTP10KF3B4] on the product page for that UPS say:

Nominal Output Voltage: 120V,208V,208V 3PH

In regards to the Symmetra LX for the US, so the model you posted, SYA12K16P, accepts an input of two phases (208v or 240v), a neutral, and a ground. It is looking for 208v or 240v nominal voltages. [this probably answers some questions too|http://nam-en.apc.com/cgi-bin/nam_en.cfg/php/enduser/std_adp.php?p_faqid=7059]

also, take a look at [this article|http://nam-en.apc.com/cgi-bin/nam_en.cfg/php/enduser/std_adp.php?p_faqid=6929] pertaining to the importance of a neutral.

on the INTERNATIONAL UNIT, so SYA12K16I, the wiring is below:

Nominal Input Voltage 230V,400V 3PH
Input Frequency 45 - 65 Hz (auto sensing)
Input Connections
Hard Wire 3 wire (1PH+N+G)
Hard Wire 5-wire (3PH + N + G)

hope that helps!

Yes it helps. Then the SUVT has an output voltage of 120Vac. Thanks, I wasn't sure because the manual doesn't say anything about that and I'm not familiar with UPS @ 120Vac.

And about the Symmetra LX, I don't understand that electrical configuration: 2PH, N, G. I know in 3 phase 2 posibles configurations:

1- 3PH and G, for example in 220Vac, voltage ph-ph 220Vac and with a floating ground
2- 3PH, N and G, for example in 220Vac, voltage ph-ph 380Vac, voltage ph-n 220Vac and voltage n-g 0Vac

So I have a 3PH and GND of 220Vac and what I need if I want to feed the Symmetra with this configuration, what kind of isolation transformer, or is it imposible to do that? Let me know if it isn't clear.
