- Integrated Sine Filter: All-pole sine filter eliminates the need for shielded cables, enabling easy retrofit into existing installations.
- 5-Step Fan Speed Control: Step0=0Hz, Step1=10Hz, Step2=20Hz, Step3=30Hz, Step4=40Hz, Step5=50Hz for precise motor adjustment.
- Motor Protection & Safety: Supports connection of thermostats (TB) or thermistors (TP) to protect motors from overheating or damage.
- Durable & Reliable Design: IP54 enclosure, wide voltage range (208–277V), and interference-compliant with EN 61000-6-2/3 standards.
- Versatile & Quiet Operation: Compatible with external rotor and other non-standard motors, allowing trouble-free parallel operation without electromagnetic noise or voltage spikes.
The FRQ5S-E-6A is a high-performance 5-step analogue speed controller designed for single-phase fans, featuring an integrated all-pole sine filter that ensures smooth, trouble-free motor operation without the need for shielded cables. Ideal for both new installations and retrofits, this controller reliably operates motors typically unsuitable for frequency inverter control, including external rotor types. It offers precise 5-step frequency adjustment (0–50Hz), potential-free operation notification, motor protection via thermostats or thermistors, and is fully compliant with EN 61000-6-2/3 standards for interference immunity and emission. Built with a durable IP54 enclosure, wide voltage range support, and a compact design, the FRQ5S-E-6A provides safe, efficient, and quiet motor control for residential, commercial, and industrial applications.
