- Integrated All-Pole Sine Filter: Ensures safe, trouble-free motor operation and reduces electromagnetic interference without the need for shielded cables.
- Flexible Analog Control: Supports 0-10V, 0-20mA, and PWM input for precise speed regulation; includes 10V DC output for external potentiometer.
- Motor Protection & Reliability: Protects motors using thermostats (TB) or thermistors (TP) and allows parallel operation without danger from voltage peaks or bearing currents.
- Retrofit & Easy Installation: Suitable for existing wiring with non-shielded cables; perfect for external rotor motors and retrofit applications.
- Durable Industrial Design: IP54-rated enclosure, wide voltage range (208-277V, 50/60Hz), and compact dimensions for versatile industrial or commercial fan installations.
The FRQS-E-10A analog speed controller is designed for single-phase fans, featuring an integrated all-pole sine filter that ensures reliable, trouble-free motor operation while eliminating the need for shielded cables. Perfect for both new installations and retrofits, this controller allows seamless operation with non-shielded cables and external rotor motors, typically not suitable for frequency inverter operation. With analog input options (0-10V, 0-20mA, PWM) and a 10V DC output for external potentiometers, the FRQS-E-10A offers flexible motor control, potential-free operation notifications, and motor protection through thermostat or thermistor connections. Its robust IP54-rated enclosure, wide voltage compatibility, and resistance to electromagnetic interference make it ideal for industrial and commercial fan systems. Lightweight yet durable, this controller combines ease of installation, retrofit convenience, and precise fan-speed control in a compact design.
