d. AC output voltage distortion:
1) Maximum 3% @ 100% linear load; maximum 8% @ 100% non-linear
(1 kVA and 2 kVA models)
2) Maximum 2% @ 100% linear load; Maximum 5% @ 100% non-linear load
(3 kVA to 20 kVA models)
e. AC output static voltage regulation: +/-1%.
f. AC output dynamic voltage regulation: +/- 8% maximum for 100% load
step at less than 10 ms recovery time
g. Overload Rating:
1) Normal Operation (Online):
a) 150% for 30 seconds
b) 125% for 1 minute
c) 105% continuous
2) Bypass Operation: Overload is limited by the upstream branch protection
feeding the UPS.
a) Typically a 10 A 2-pole circuit breaker should be fitted at the input of the
1 kVA models.
b) Typically a 16 A 2-pole circuit breaker should be fitted at the input of the
2 kVA, 2.2 kVA, and 3 kVA models.
c) Typically a 32 A 2-pole circuit breaker should be fitted at the input of the
5 kVA and 6 kVA models.
d) For the 8k VA models, typically a 50 A 2-pole circuit breaker should be
fitted at the input with a single phase supply, and a 50 A 4-pole circuit
breaker should be fitted at the input with a three phase supply.
e) For the 10 kVA models, typically a 63 A 2-pole circuit breaker should be
fitted at the input with a single phase supply, and typically a 63 A 4-pole
circuit breaker should be fitted at the input with a three phase supply.
f) For the 15 kVA model, typically a 100 A circuit breaker should be fitted
at the input for each Phase plus Neutral with single phase input and
output or with three phase input and single phase output. Typically a
35 A or 40 A circuit breaker should be fitted at the input for each Phase
and Neutral with three phase input and three phase output.
g) For the 20 kVA model, typically a 125 A circuit breaker should be fitted
at the input for each Phase plus Neutral with single phase input and
output or with three phase input and single phase output. Typically a 50
A circuit breaker should be fitted at the input for each Phase plus
Neutral with three phase input and three phase output.
h. Output Power Factor Rating:
1) 0.2 –1.0 lagging
2) Nominal: 0.7 lagging.
i. Crest Factor: 3:1.
