Robust & Durable Design – IP54 rated enclosure, 208-277V voltage range, 6A maximum current, operating temperature up to 55°C.
The FRQS-E-6A analog speed controller is designed for precise and reliable control of single-phase fans, including external rotor motors not typically suitable for frequency inverters. Equipped with an integrated all-pole sine filter, it eliminates the need for shielded cables, making retrofitting into existing systems effortless. The controller supports 0-10V analog input, 0-20mA or PWM signals, and offers 10V DC output for external potentiometer control. It provides motor protection via thermostats or thermistors, ensures interference-free operation (EN 61000-6-2/6-3), and allows safe parallel operation of multiple motors. With a wide voltage range of 208-277V, an IP54 enclosure, and a compact design, the FRQS-E-6A is ideal for modern fan systems requiring efficient, trouble-free operation.
