FC20: Small size, big impact.

The FC20 Series is Janson Controls’ most compact and cost-effective solution for basic motor control. Specifically engineered for light-duty applications where panel space and budget are critical, it delivers reliable performance with unmatched ease of use.

Space-Saving Design:Its ultra-compact footprint allows for flexible installation, including direct mounting options, making it the perfect fit for portable equipment and small-scale machinery.

Plug-and-Play Simplicity:
Equipped with a built-in speed potentiometer (control knob), the FC20 allows users to manage basic tasks immediately without the need for complex programming or external controllers.

Intelligent Protection: Powered by an advanced Intelligent Power Module (IPM), the FC20 features integrated overcurrent and thermal protection, ensuring a long, maintenance-free service life even in continuous operation.

Versatile Automation: Despite its miniature size, it features a built-in PID controller for simple constant pressure or flow control. This makes it a reliable and versatile choice for conveyors, fans, and small centrifugal pumps.

1.Precise & Reliable Core Drive

  • Wide-Range 0-300Hz: Tailored for light-duty loads like fans and pumps with customizable V/F curves.

  • Built-in Smart PID: Enables easy closed-loop control for pressure or flow variables, perfect for small-scale water supply or air systems.

2.Robust Hardware Foundation

  • Advanced IPM Module: Utilizes Intelligent Power Modules to prevent failures from overvoltage or overheating, extending the drive's lifespan in harsh environments.

  • Stable Low-Frequency Torque: Optimized algorithms ensure smooth starts for conveyor belts, preventing jerky movements under load.

3.User-Centric Engineering

  • Instant Manual Control: The onboard speed knob and support for external panels make it incredibly easy for non-technical users to operate.

  • Meter-Mounting Support: Flexible installation options to fit various cabinet layouts and machine designs.

4.Quiet & Efficient Operation

  • Low-Noise Technology: Advanced PWM modulation reduces motor "humming," ideal for indoor food processing or commercial environments.

  • Superior Immunity: Optimized EMC design ensures stable operation even in electrically noisy industrial settings.
