Additional specifications and description
Why control building ventilation
Ventilation is the exchange of indoor and outdoor air. Without proper ventilation the building will seal in harmful pollutants, such as carbon monoxide and moisture that can be harmful to both the building and its occupants. Apart from natural ventilation (i.e. uncontrolled air movement from windows, doors, or cracks in the home), a ventilation system provides controlled, uniform ventilation throughout the building. It entails using one or more fans and duct systems to exhaust stale air and/or supply fresh air into the house. To optimize the supply of fresh air and reduce costs mechanical ventilation needs to be controlled.
If you are looking for simplified ventilation regulation, the USX is what you need! Via its built-in potentiometer the fan speed can be set from minimum to maximum speed by turning the potentiometer clockwise. The higher the fan speed, the higher the energy consumption. Reducing the fan speed by just 25% results in energy savings of more than 50%. Depending on the ventilation system, heating costs can also be reduced by optimizing fan speed.
Technology used
This controller uses TRIAC technology (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.
Minimum speed setting
Depending on the motor type, the motor might produce a little more noise at lower speeds (due to the imperfect sinusoidal shape of the motor voltage). The minimum motor voltage can be adjusted 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. It is intended for one-time setting upon installation and there is no need to tamper it every now and then.
Reduced fan speed uses significantly less power than maximum operation and can often be employed, typically during unoccupied or low occupancy.
Application
The series is developed to control AC fans via reducing the motor voltage. AC fans run on an alternating current and convert alternating current into mechanical power. These controllers reduce the voltage to the motor via phase angle control. Therefore, they are 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.
US standard
This variable fan speed controller is intended for use where utility power is 120 Volts. American electrical systems run on 120 Volt power supply. The whole design of the USX series is consistent with American performance requirements of the materials and accessories used in the fabrication of electronic components, devices, and equipment.
Quality guarantee
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.
Reliable enclosure
The solid enclosure of the device is made of high-quality R-ABS, UL94-V0 plastic in neutral colour. This material is flame retardant and provides good protection against impacts and dirt. It can be wall-mounted in indoors.
