Variable fan speed controller | US design | 1,5 A | 120 VAC, 60 Hz
Product description
Explore the USX-7-15-DT from the USX series, meticulously engineered electronic fan speed controllers for precise regulation of single-phase voltage-controllable motors.
With a potentiometer and internal trimmer, achieve optimum performance.
Operating at 120 VAC ± 10% / 60 Hz, this controller offers regulated output from 20% to 70% of Us, ensuring efficient control in temperatures ranging from -5 to 40 °C.
With a maximum motor current of 1.5 A, trust the USX series for reliable and expert motor speed control
Additional specifications and description
Why choose USX
This is a manual fan speed controller that regulates motor speed from low to high revs. It is controlled via its built-in potentiometer. Turning the pot clockwise starts the motor at low speed. When you turn it further clockwise, the motor accelerates to the maximum speed. The minimum motor speed is adjustable via an internal trimmer within the range 20 – 70 % of the supply voltage (Us). It is a simple and reliable control solution for ventilation systems or air-conditioning systems in residential environments and well as for direct AC fan / motor control of whole house fans, fireplace blowers, humidifiers, range hoods, etc.
There is no need to overdimension this controller. This means that of your fan has a maximum current of 1,5 A, a controller of the same rating will be enough to control it. It can control several 120 V motors with a total maximum current equal to its rated current. On a continuous basis!
American standard
This variable fan speed controller is intended for use in North America which run on 120 Volts whereas most of the rest of the world run their electrical systems at 230 Volts. The output voltage is regulated steplessly i.e. the speed of the fan is infinitely variable. The wiring, the gauge and installation are consistent with American performance requirements of the materials and accessories used in the fabrication of electronic components, devices, and equipment.
Superior quality
This fan speed controller is made in Europe using the most reliable and modern electronic components. Its enclosure is produced by our sister company known for its high-quality technical plastic products.
Simplicity of installation and control
The USX is intended for surface mounting and therefore features pre-stamped cable entries at the rear of the enclosure. All you need to do is gently knock them out and mount the device onto the panel or wall using suitable screws and/or dowels. This fan speed controller does not require any configuration. Once connected, the fan speed controller is ready to use! The fan speed is adjusted manually via the built-in potentiometer. This potentiometer features an OFF position. If necessary, the minimum motor voltage can be adjusted via the internal minimum speed trimmer. Depending on the motor type, it might produce a little more noise at lower speeds (due to the imperfect sinusoidal shape of the motor voltage). As a rule, the minimum motor voltage is adjusted in order to avoid motor stalling at low speed and optimize fan speed for your ventilation system. That is why this controller features the internal minimum speed trimmer. Reduced fan speed uses significantly less power than maximum operation and can often be employed, typically during unoccupied or low occupancy.
TRIAC technique
This controller uses TRIAC (phase angle control) to adjust the motor voltage and to control the fan speed. TRIAC cuts parts of the incoming voltage to reduce the overall motor voltage. Thanks to this technology, the fan speed controller operates without excessive humming and buzzing.
Local AC fan speed control
This series is intended for AC fans and control is realised via reducing the motor voltage. AC motors run on an alternating current and convert alternating current into mechanical power. This means that the series is suitable only for voltage controllable motors. You can connect several motors to the controller as long as the current limit is not exceeded. If you are not sure about your motor type, we strongly advise you to read carefully its accompanying documentation or contact the motor manufacturer.
Solid enclosure
The enclosure is made of high-quality R-ABS, UL94-V0 plastic. This material is flame retardant and provides good protection against impacts. It can be wall-mounted indoors.
