208V
Run single phase equipment on 3 phase power
Yes. You can run single phase equipment on three phase power.
Benefit
Power from a 3-phase circuit equals voltage multiplied by current multiplied by 1.732 (the square root for 3). As a result, a 3-phase circuit provides 1.732 more power than single phase power, which in turn reduces energy costs. [1]

Global Power
"Generally speaking, most modern servers are rated for 100-240V or 250V operation, much like the majority of today’s consumer electronics. The simple fact is that building a global power supply is oftentimes more cost efficient than building a narrow voltage input range power supply. There is great benefit in being able to simply match a power cord and get running."

Power Supply Efficiency vs Input Voltage
Why 208 Volt is More Efficient than 110 Volt Input for Server Racks - HostDime Blog - https://www.hostdime.com/blog/208-volt-server/
"There’s a one to three percent improvement in power supply efficiency with the increased voltage, which will save between $4 and $31 annually per server in electrical cost."
Tons of Cooling
= Volt-amps / 3516.85 = Watts / 3516.85
3516.85 volt-ampere = 1 tons (rt)
