Note
(1)
If you apply the recommended reactor, More than 85% power factor and THD 40% less
operation is possible in generally power environment. However, the condition is based on the
rated load. Improvement in the case of light load is reduced.
(2)
During operation, the input power factor and harmonic wave is affected by the impedance of
the line
Therefore, even applying the reactor, the input power factor and THD improvement can be
lowered than the displayed in (1) by the installed transformer capacity, the transformer
impedance, line length
(3)
Generally, the higher the value of the inductance L of applied reactor, improvement of power
factor and harmonic effects increases. But loss due to voltage drop will increase. Therefore,
use the recommended reactor.
(4)
IS7 has a mounted DC reactor products based on the Normal Duty load factor. In operation
Heavy Duty, Improvement may be lower than the displayed in (1)
Caution
[English]
Use Class H or RK5 UL listed Input fuses and UL listed breakers ONLY. See the table above for the
voltage and current ratings for the fuses and breakers.
[French]
Utiliser UNIQUEMENT des fusibles d’entrée homologués de Classe H ou RK5 UL et des disjoncteurs
UL . Se reporter au tableau ci-dessus pour la tension et le courant nominal des fusibless et des
disjoncteurs.

2.1) Specifications of the DC reactor
IS7 200V 30 ~ 75kW, 400V 280 ~ 375kW capacity products does not have a built-in DC reactor. If you
wish to use the product by applying a DC reactor, please refer to the specifications of the DC reactor.
