ECOtronic PowerLine EC – PCDEC50DD

The ECOtronic EC Series of PowerLine centrifugal fan incorporates an IE5* rated Electronically Commutated (EC) shaft motor delivering ultra energy efficient operation with the benefit of in-built variable speed control. Via a range of common control signals, the ECOtronic can be easily designed into a Demand Control Ventilation system without the need for a VSD and overload protection.

The ECOtronic EC fans are a simple “plug and play” system which means installers do not need to have specialised control programming knowledge. The series is available in 4 sizes ranging from 315 to 450mm diameter.

• EC motor features reverse polarity protection, locked rotor protection and soft start
• No additional protection such as current overloads are required
• Can be manually speed controlled by pressing 2 internal motor buttons
• Can be remote speed controlled with either a 2-10V or 4-20mA input signal or a 10 to 95% frequency duty cycle
• Can be run as an independent ventilation source or integrated into most building management systems
• Maximum operating speed can be adjusted from 1800rpm to 200rpm
• On board fault identification LED will flash according to fault type
• Integrated “Fire Mode” function forces motor to continue working under adverse conditions (at full speed)
• Easy to fit 35mm TDF profile flange connections.
• Robust, yet lightweight galvanised steel construction.
• Operating temperature: -20 °C to +60 °C when air velocity exceeds 5 m/s, otherwise -20 °C to +40 °C

EC motors should be directly connected to their appropriate AC supply. EC motors should not be regularly power cycled.
* The IE5 efficiency level is not currently defined by the IEC standard, however the intent is for IE5 motors to have approximately a 20% reduction in losses against IE4 motors.
