Elta AC Electronic Controller 149-EL61TK 6 Amp

The Elta 149-EL61TK is a 6 Amp single phase electronic speed controller for AC fans fitted with thermal cut-out protection. It gives stepless speed adjustment and wires into the motor's thermal contacts, switching off with a trip indicator if the motor overheats.It runs on a 220 to 240V 50Hz single phase supply, has an IP51 enclosure, a fitted motor protection fuse, minimum and maximum speed presets, an illuminated on/off switch and a start button, and is suitable for operating temperatures up to 40°C. 6 Amp Stepless electronic controller Single phase AC What it is best used forStepless control of larger single phase AC axial fans up to 6 A peak that have thermal contacts: commercial kitchens, workshops, warehouses and plant rooms. Elta specify it for the Raptor SPA560/6-1AC plate fan and the SDA450/4-1AC, SDA500/4-1AC and SDA630/6-1AC case mounted fans.Not for EC fans (use a 0-10V EC controller) or three phase motors. If the motor hums at low speed on electronic control, a transformer controller is the quieter choice.Why choose this over alternativesCompatible fans on eFans, as listed in Elta's datasheets: SPA560/6-1AC, SDA450/4-1AC, SDA500/4-1AC and SDA630/6-1AC.The thermal contact input latches the fan off on overheat until someone presses the start button, which the standard 149-EL61 cannot do. For smaller TK fans up to 3 A, the 149-EL31TK is the lower cost match. For hum-free stepped control of the same SDA fans, Elta list the 149-TC18 transformer controller.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. Connect the fan's thermal cut-out contacts to the controller. If the cut-out opens, the controller switches off and the trip indicator lights; press the start button to restart once the motor has cooled. 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.
