Active harmonic filter from the AccuSine family that contributes to the stabilization of electrical networks by reducing harmonics, correcting the power factor, and enabling load balancing. It is specifically designed for demanding electrical conditions, heavy industrial applications, and critical environments. This version has a protection class of UL Type OPEN or IP00 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 300 amperes. The housing is wall-mounted, allows for cable entry from below, and is supplied 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, and 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 582 millimeters in width, 438 millimeters in depth, 1560 millimeters in height, and the product weight is 210 kg.
