FRQ
FRQs are frequency converters designed for single-phase and three-phase fans. The FRQ frequency converters allow you to control, manage and monitor complex systems and motors with precise settings of the required parameters. The advantage of the frequency converters is the full support of all inputs and outputs including accessory boards and very compact size. FRQS frequency converters are equipped with a sine filter for all poles, therefore no shielded cable is required. FRQ5 frequency converters are equipped with a five-stage switch.
