The Vents RS-1-400N is a stepless fan speed controller designed for regulating single-phase fan motors controlled by voltage. The controller is surface-mounted on a wall and adjusted via a rotary knob that controls the output voltage steplessly from the minimum setting (lowest stable speed) up to 230V (full speed). The minimum speed point can be fine-tuned using a built-in potentiometer. The rated current is 1.8 A and the safe operating range covers motors of 250–320 W. Motors up to 350 W can be connected provided the rated current on the motor's nameplate does not exceed 1.5–1.6 A.

It is possible to connect several fans in parallel to a single controller, provided the combined current draw does not exceed the controller's rated current of 1.8 A. The input circuit is protected by a replaceable fuse against overload, and the controller incorporates a filter against high-frequency interference in the mains supply.

The housing is manufactured from plastic, ingress protection class IP40. Dimensions: 78 × 78 × 63 mm. Note that thyristor-type controllers of this kind generate heat during operation — adequate ventilation around the controller is important. A controller with a rated current clearly above the motor's actual current draw runs cooler and more reliably.

What is the Vents RS-1-400N fan speed controller and why should you choose it?

The Vents RS-1-400N is a thyristor-based fan speed controller for single-phase AC fan motors. Stepless control via a rotary knob gives precise control over the fan's airflow without needing to switch the fan off and restart it. The controller also switches the fan on and off via the same knob. The built-in replaceable fuse and HF filter protect both the controller and other electronics against interference. The surface-mount construction makes installation straightforward – the controller is screwed directly to the wall without any built-in installation work. The white colour and compact dimensions (78 × 78 × 63 mm) suit most interiors.

What environments is the Vents RS-1-400N fan speed controller suited to?

The controller suits ventilation systems in residential spaces, offices, workshops, warehouses and agricultural buildings where stepless control of fan speed is needed. It is suitable for single-phase wall fans, duct fans and roof fans with AC motors controlled by voltage. The controller can also be connected to the Eberg VEXO range and similar wall fans supplied with a separate controller. The IP40 ingress protection class is intended for indoor use in dry environments.

Technical Specifications

Frequently Asked Questions (FAQ)

Does the Vents RS-1-400N fan speed controller work with Eberg VEXO fans and similar single-phase wall fans?

Yes, the Vents RS-1-400N fan speed controller works with single-phase AC fan motors controlled by voltage, which includes the Eberg VEXO range and similar wall fans. The controller adjusts the fan speed steplessly from the lowest stable setting up to full speed via a rotary knob. Check that the fan motor's rated current does not exceed 1.5–1.6 A and that the motor power falls within the operating range of 250–350 W.

What rated current and motor power range does the Vents RS-1-400N fan speed controller cover?

The Vents RS-1-400N fan speed controller has a rated current of 1.8 A. The safe operating range covers motors of 250–320 W. Motors up to 350 W can be connected provided the rated current on the motor's nameplate does not exceed 1.5–1.6 A. Multiple fans can be connected in parallel if the combined current draw does not exceed 1.8 A. The controller is protected by a replaceable fuse and an HF interference filter. Dimensions: 78 × 78 × 63 mm, ingress protection class IP40.

What sets the Vents RS-1-400N fan speed controller apart from other fan controllers on Verktygsgrossen?

The Vents RS-1-400N stands out through its stepless thyristor control that gives precise adjustment from the lowest stable speed to full speed via a single rotary knob, which also switches the fan on and off. The built-in replaceable fuse and HF filter protect against overload and mains interference. The surface-mount construction (78 × 78 × 63 mm) makes installation straightforward without any built-in work. For cooler and more reliable operation, choose a controller with a rated current clearly above the motor's actual current draw.
