Get a quote
The Schaffner AHF 75 A 690V is an indoor wall-mounted three-wire active filter designed to manage power quality in electrical systems. Code 778-6044L/HL, this unit features a 4.3” LCD display for measurement visualization and settings, powered by a digital controller. It provides a maximum harmonic current compensation of 60A per phase, tackling harmonics up to the 49th order while maintaining a residual harmonic distortion rate THDI of less than 5 percent. Additionally, the device compensates reactive power and balances currents across the three phases. Built with an IP20 external protection grade, it measures 500x250 h.675 mm with an approximate weight of 70 kg. The system utilizes forced ventilation delivering over 151 L/s and includes an RS485 communication port supporting the Modbus protocol in RTU and TCP/IP formats.
