Audible Noise
~65dB @ 1 meter from the front of the unit
Operating Temperature
32 – 104
°
F (0 – 40
°
C); optimal temperature is 77
°
F (25

–
Specified at rated conditions under balanced linear loads.
2
–
Battery backup time may vary depending on the operating conditions and ambient temperature at the installation site. An initial
charge time of 24 hrs is necessary to obtain proper battery performance level before the unit is placed in operation.
3
–
At 6600 ft. (2000 m) above sea level, output capacity should be derated by 3% (Consult factory for higher elevations).
4 – Prolonged operation at this level requires derating of the maximum Operating Temperature to 90
°
F ( 32
°
C).
5 – SHORT TERM operation only (e.g. Brownouts). Operation at this level requires derating the maximum Operating Temperature to 95
°
F ( 35
°
C).
4200FA Efficiencies and Thermal Losses at Various Loads
7.10
The tables below list typical efficiency at 100% load, and thermal loss at various loads, for the
15/25/30/50kVA units in three configurations:
•
UPS without input/output internal transformers
•
UPS with Internal input isolation transformer
•
UPS with internal input isolation transformer and autotransformer
(NOTE: The efficiencies and thermal values listed are representative only. Individual performance may
be different due to variations in operating environment, manufacture, transformer type, and transformer
performance at different loads.)
