Overview

Active filter PQF has been present globally in the market for more than 20 years. It makes installations compliant with prevailing power quality regulations by mitigating harmonic pollution, load unbalance and reactive power demand.

Harmonic filtering

Individual harmonic selection capability and unique filtering efficiency due to three-level inverter and proven control system

PQactiF has an improved capability of filtering up to 25harmonics simultaneously, between the orders H2 to H50.

Reactive power compensation

Stepless reactive power compensation for both inductive and capacitive loads, target settable
PQactiF can perform precise stepless reactive power compensation of both inductive and capacitive loads. The target power factor is programmable from 0.6 (inductive) to 0.6 (capacitive) which makes PQactiF a superior alternative to a conventional capacitor bank. This also allows compensation of loads fed by generators without the risk of overcompensation.

Load balancing

Balancing the load currents to address neutralto-earth voltages and negative impact of voltage unbalance

Load balancing feature is available in both 3-wire and 4-wire systems between phases and between phase and neutral.

This feature helps to improve voltage unbalance on the phases which increases the safety of the installation and allows sensitive loads to operate.

Enhanced communication features

Wi-Fi enabled modules allow users to monitor and set parameters via smartphone or computer
Parameter settings and simple diagnostics can be performed by a web server on a mobile device. The optional user-friendly HMI (called PQoptiM) interface offers direct access to filter control, programming and monitoring with its 7-inch touchscreen.

PQactiF is offered in two differentmodule ratings of 20 A and 40 A.Depending on the application, PQactiF is available in either as a module, a wall-mounted solution or a standalone cabinet.
