Product description

Mounting: Designed for DIN rail mounting.

Motor Compatibility: Controls single-phase, voltage-controllable motors up to 1.5 A max current.

Voltage Control: Adjusts output voltage from 100 to 230 VAC via a rotary knob.

Speed Adjustment: Rotary knob allows regulation from maximum to minimum speed, including an OFF position.

Fine-Tuning: Minimum speed can be fine-tuned via an internal trimmer.

Status Indicator: A green LED indicates operational status.


Additional specifications and description

 
How Does This Controller Manually Regulate AC Motor Speed?
This manually operated industrial fan speed controller regulates motor speed from maximum to minimum. When the rotary knob is in OFF position, the motor is not active. Turning the knob clockwise starts the motor at the highest speed. When the knob is turned further clockwise, the motor slows down to the minimum speed setting. 

What Motor Types Are Compatible with This Controller?
 
Electronic fan speed controller, 1,5 A
The device is intended only for voltage controllable fans / motors, i.e. AC fans. These run on an alternating current and convert alternating current into mechanical power. This controller reduces the voltage provided to the fans via phase-angle control using TRIAC technology. If you are not sure about your motor type, we strongly advise you to read carefully its accompanying documentation or contact the motor manufacturer.

How Is Minimum Motor Speed Adjusted and Optimized?
The minimum motor speed is adjustable via the trimmer on the front within the range 20 – 70 % of the supply voltage. As a rule, the minimum motor voltage is adjusted to avoid motor stalling at low speed. The trimmer is adjusted so that the motor does not stop due to mains voltage variations. What is more, when the motor works at very low revs there is more humming and buzzing. 

Can the OFF Position of the Controller Be Deactivated?
The OFF position can be deactivated by connecting the 230 VAC supply voltage to the unregulated output, i.e. to terminals L1 and N (intended for the unregulated output). In this case, the motor will run when the power supply is present. If you want to keep the OFF position enabled, connect the supply voltage via terminals L and N, as standard. 
 
What Is the Purpose and Application of the Unregulated Output?
If the supply voltage is connected to L and N, the unregulated output is active when the motor is enabled. The unregulated output can be used to control external devices. It is intended for use in applications where extra precise regulation or low ripple is not required, such as an LED lamp (as a run indicator), external relays, solenoids, dampers and anything that is ideal for non-critical loads. When the fan stops, the external device is switched off. When the fan is active, the external device is on. Because this output is either ON (230 Volt) or OFF (0 Volt), it is called ‘unregulated output’. 

How Does the LED Indicator Display Operational Status?
The green LED indicates the operation status. During normal motor operation, the LED is on.

Can Multiple Motors Be Connected to a Single Controller?
You can connect several motors to the controller as long as the current limit is not exceeded. In this case all of them will run at the same speed. 

What Are the Installation Guidelines and Enclosure Features?
This fan speed controller is intended for mounting onto a DIN rail inside an equipment racks – the perfect solution for industrial control equipment. DIN rails are metal rails that conform to industry standards and are used to mount industrial processing equipment. DIN rail electronics have been around for a long time and are becoming increasingly popular in industrial applications across a wide range of industries. The enclosure provides an IP30 protection against the ingress of dirt and dust.

Labai kompaktiškas su minimalaus išėjimo nustatymu elektroninis reguliatorius, iš aukščio telpa į automatukų dėžutę.

Kupuje te regulatory od ponad roku, dobra jakość, stabilna praca, mały rozmiar - czasami mała dostępność - polecam do montażu w szafach automatyki
