AC motor 10 A | Remote speed control | TK monitoring | LED indicator

This electronic fan speed controller provides precise fan speed regulation for 230 V single-phase motors with a maximum current of 10 A. It features an invertible analogue input signal, accepting either 0-10 / 10-0 VDC or 0-20 / 20-0 mA. It also includes a remote control input with selectable functionality (normal or timer), as well as an analogue input with normal or logic functionality for timer-based starts. The minimum and maximum output voltage can be set by internal trimmers or via Modbus RTU communication. The off value is also adjustable by trimmer or via Modbus. The device supports both kick start and soft start modes. It has one regulated output for the motor, one unregulated output (230 VAC / max. 2 A) for a 3-wire motor connection or voltage supply, and a low voltage supply output (+12 VDC / 1 mA) for an external 10 kΩ potentiometer. The device provides clear status indicators with a green LED for normal operation and a red LED for overheating. It also features an alarm output (230 VAC / 1 A) and is designed for DIN rail mounting.

The LTV Potentiometer is a device for controlling ventilation systems. It operates on a 230 VAC supply and provides a 0-10 VDC output signal to manage devices like EC fans and valve actuators. The rotary knob offers continuous control and has a distinct OFF-position for zero output. A green LED lights up when the output voltage is above 0V, indicating the system is active. It turns off when the system is in the OFF-position.The splash-proof enclosure supports both inset mounting (IP44) and surface mounting (IP54).
