UNINTERRUPTIBLE POWER SUPPLY RATINGS AND OPERATING CHARACTERISTICS
A.
UPS Continuous Ratings. The UPS shall be rated:
UPS Rating (max)
Optional Rating (1)
Optional Rating (2) Optional Rating (3)
40kVA/36kW
30kVA/27kW
20kVA/18kW
n/a
80kVA/72kW
60kVA/54kW
50kVA/45kW
40kVA/36kW
120kVA/108kW
100kVA/90kW
n/a

UPS Rating (max) is the maximum output possible from the UPS (for a load
power factor range of 0.9 lagging to 0.9 leading). The UPS shall not require de-
rating when supporting a leading power factor load of 0.9 or greater. The UPS
may be ordered with any of the three (3) optional ratings (where available) and
later upgraded to its corresponding full UPS Rating (max).
B.
Rectifier/charger input:
1.
Nominal three phase input voltage: 208 (or 480) VAC:
3-wire plus ground for 3-wire plus ground output configuration
2.
Operating input voltage range: +10%, -15% of average nominal input voltage
without battery discharge.
3.
For 60Hz systems, operating input frequency range shall be 55 to 65Hz.
4.
Input power factor 0.99 lagging.
5.
Normal input current limit: The UPS shall have the following programmable input
current limit settings while operating in normal mode:
a)
Rectifier/charger input current limit shall be adjustable from 100 to 115%
of full-load input current.
b)
Battery input current limit shall be adjustable from 10% to 15% of the
UPS full load input current regardless of the actual load on the UPS.
6.
On generator input current limit: The UPS shall have the following programmable
input current limit settings while operating in normal mode on generator:
a)
Rectifier/charger input current limit shall be adjustable from 100% to
115% of full-load input current.
b)
Battery recharge input current limit shall be adjustable from 10% to 15%
of the UPS full load input current regardless of the actual load on the
UPS.
7.
Input current total harmonic distortion (THD) shall be less than 4.5%.
8.
Power walk-in: Ramp-up to full utility load adjustable from 3 seconds to 60
seconds.
C.
Bypass input:
