EC (ELECTRONICALLY COMMUTATED) FAN MOTORS
Maintenance-free, external rotor axial fans. Protective grid compliant with EN ISO 13857. 3-phase input, nominal voltage 400V (±10%), frequency 50 / 60Hz.
Integrated PID control, RS485 MODBUS communications interface, volt-free contact for reading operating conditions and alarm states (motor and electronic overtemperature, mains voltage and phase failure, locked rotor protection), "soft start" function. Active analog output 10 VDC (max 10 mA).
Insulation class F; IP54 degree of protection (EN 60529).
Compliant with EC Standard EN 61800-5-1. Other homologation available on request.
Compliant with EC Directives 2004/108 EMC, 2006/95 LVD, 2009/125 ErP.
Power and sound pressure compliant with Standard EN 13487.
N.B.: the sound pressure level at a given distance is calculated in free field conditions, therefore it is merely indicative as it will be affected by the characteristics of the area where it is installed.
N.B.: EC electronic fans are not compatible with electrical systems with NEUTRAL isolated from ground (IT). Dedicated versions available on request.
