Electronic Speed Controller 149 EL61 6 Amp

The Elta 149-EL61 is a 6 Amp single phase electronic speed controller for voltage controllable AC fan motors. It gives stepless speed adjustment for setting the fan duty precisely during commissioning.It runs on a 220 to 240V 50Hz single phase supply, has an IP51 enclosure, a fitted motor protection fuse and minimum and maximum speed presets, and is suitable for operating temperatures up to 40°C. It weighs 0.40 kg and suits two or three wire control. 6 Amp Stepless electronic controller Single phase AC What it is best used forStepless speed control of larger single phase AC fans, or two smaller fans, with a combined peak current up to 6 A: kitchen extract, plant rooms, workshops and general supply or extract duties where the airflow needs balancing on site.Elta's datasheets specify the TK version (149-EL61TK) for their own 6 A plate and case mounted fans, because those fans have thermal cut-out contacts. Use this standard EL61 where the fan has no thermal contacts to wire in. It is not for EC fans or three phase motors.Why choose this over alternativesAgainst the 3 A 149-EL31, the EL61 doubles the current rating in a near identical housing (0.40 kg against 0.35 kg). Against the 149-EL61TK, it has no thermal contact input, so choose the TK where the fan has thermal cut-out leads.If stepless control causes hum on your motor, a 5-step transformer controller such as the 8 Amp 149-TC18 avoids it, at the cost of fixed steps and a much heavier unit.Installation notes Check the fan's rating plate: the motor's peak current must not exceed 6 A. Fix the controller in a dry indoor position; the enclosure is IP51 and rated for operating temperatures up to 40°C. Wire to the terminal block (L, N, U1, U2, AUX, E) exactly as shown on Elta's wiring diagram, with the 240V supply in and the fan's variable live (brown) and neutral (blue) out. Two or three wire control is supported. Set the minimum and maximum speed presets during commissioning so the fan cannot be turned down to a speed where it stalls or under-ventilates. Installation by a qualified electrician with a means of isolation in the supply.
