The IRX PRO model is a frequency inverter suitable for evaporative air conditioners. It has specific functions for this application, such as “Climate”, “Ventilate”, “Cyclic Timer” (for energy saving), “Swing”, “Drain” and “Exhaust”. It drives motors of up to 3CV and allows different levels of fan speed. IRX PRO frequency inverters have a level sensor input and several protection parameters, including against motor overload. Its inverter module can be installed inside the air conditioner due to the IP64 degree of protection (resistant to water jets). They allow the air conditioners to be easily controlled through two HMI options (superimposed or recessed) or through a remote control. Both alternatives have access keys to the main functions of the device.
