Can a 3-phase APC SYMSTRF3I still power up on single phase supply.

Anonymous user · ‎2021-06-26

We moved our 3-phase APC SYMSTRF3I UPS to another building, which only has a single phase supply currenlty. Is it possible to power this UPS with just a single phase (UPS will only be supporting 2 servers). If possible could you please let me know how I could connect and power up the UPS. Thanks

SYMSTRF3I can be used in either 3:1 or 1:1 mode. The SYPM power module is universal and the 3:1 chassis allows for full current to pass through the AC_IN1 bus.

In 1:1 mode, acceptable nominal input (Hot-Neutral-Ground) would be 220/230/240 as you would expect.

And the full *3:1* user manual can be found here:
