Active harmonic filter from the AccuSine family that contributes to the stabilization of electrical networks by reducing harmonics, correcting the reactive power factor, and enabling load balancing. It is specifically designed for demanding electrical conditions, heavy industrial applications, and critical environments. This version has an IP31 protection rating and can be connected to low-voltage networks with a voltage of 380 volts to 480 volts. It is specified for a standard output current of 120 amperes. The housing is floor-standing, allows cable entry from the top or bottom, and is delivered in RAL7035 light gray. This active network filter achieves a performance THDi of less than or equal to 3%, exceeding standard requirements, and is certified according to CE, UL, IBC 2015 AC156, EAC, RCM. It complies with IEC 62477-1, IEC 61000-6-2, IEC 61000-6-4, IEC 61439-1, UL508, and IEEE 519-2014. Up to 10 devices of different power ratings can be connected in parallel to achieve a maximum compensation of 3000A per current transformer set. The external dimensions of the housing are 800 millimeters in width, 500 millimeters in depth, 2100 millimeters in height, and the product weight is 279 kg.
