Twenty-five years of excellence, seen from a different perspective
Sentera has grown into a leading manufacturer of, among other things, fan speed controllers and sensors for HVAC and ventilation systems. For 25 years, our products have been used worldwide - visibly and invisibly - to monitor and optimize the air quality in living rooms, schools, conference rooms and industrial or agricultural buildings. Ventilation and ventilation controls are an indispensable part of our daily lives today. So it's time to look at our 'favorites' from a different perspective.

1997 Twenty-five years ago, 1997: Kofi Annan is appointed Secretary General of the United Nations, Hong Kong is handed over by the United Kingdom to the People's Republic of China, the US Pathfinder probe lands on Mars, Harry Potter and the Philosopher's Stone (part one of the Harry Potter series) appears, Google is founded and the Kyoto treaty sets guidelines for limiting greenhouse gas emissions. In the same year, the Belgian entrepreneur Jos Raskin founded the Sentera group.
The start: transformer fan speed controllers Sentera's story begins with the development of transformer fan speed controllers for AC motors. Sentera transformer fan speed controllers are cost efficient and have proven to be very reliable and robust. They can be used when there is an unstable supply voltage, they are easy to install and require little to no configuration. The Sentera transformer fan speed controllers are available in many versions (max. 20 A) with a supply voltage of 115 VAC to 400 VAC and with manual control or control based on an analogue or Modbus signal.
Electronic fan speed controllers with microprocessors Sentera electronic fan speed controllers are available for stepless speed control of AC motors. These compact fan speed controllers use phase angle control (TRIAC) to control the motor speed. These electronic fan speed controllers are also equipped with microprocessors that perfectly detect the zero crossing of the sine wave and thus guarantee a precise control and a silent motor operation. These electronic fan speed controllers are available in many versions (max. 10 A) with a supply voltage of 110 VAC to 240 VAC and with manual control or control based on an analogue or Modbus signal.
Potentiometers for EC fans Unlike AC motors, EC motors are equipped with a built-in speed controller. An EC motor therefore only requires a control signal that indicates the requested fan speed. This control signal can be digital (Modbus RTU communication) or analogue (usually 0-10 Volt). Sentera offers solutions for both applications in the form of 3-position switches and potentiometers. The Sentera sensors with analogue output can also be used for direct control of EC motors.
HVAC control solutions In addition to fan speed controllers, Sentera also developed a wide range of sensors, power supplies, and network accessories. Together, our products provide smart and efficient solutions for numerous HVAC control systems.

Sentera I/O modules are Modbus RTU compatibleSentera I/O modules are Modbus RTU compatible. They are of course used in Sentera HVAC solutions, but because they are universal they can also be useful for your project or product.
Fire alarm panels, motion detection, door contacts, etc. ... Sometimes your (HVAC) application interacts with external equipment. Sentera offers a full range of converters or I/O modules. They are widely used in industrial and automation applications, but home automation or ventilation solutions for domestic use also make full use of I/O modules. I/O modules are the interface between a controller and external equipment.>>>
