SpeedControl 1145 E 3KW CP dc/dc is an inverter for control of 3-phased motors up to 3KW / 3x14A supplied by 1-phase. The inverter is supplied in a metal enclosure for demanding environment and mounted on a flat cold plate. The compact construction and the flat cold plate opens the possibility of mounting the inverter directly on a stable, non vibrating, cool plane surface . When the surface, on which the inverter is mounted, is cold enough there are no need for active cooling which makes the sound level of SpeedControl 1145 very low. Furthermore, the SpeedControl 1145 is maintenance free - all parts are integrated within the inverter and no extra capacitors nor induction coils are necessary.

SpeedControl E 1145 also comes with integrated APFC (Active Power Factor Correction), ensuring that current consumed on the grid is sinus curved so that Norms and EN-demands are met.

SpeedControl 1145 is designed especially for the growing market of energy saving ventilators, heat pumps and air handling units. SpeedControl 1145 is also a sensorless inverter meaning that no sensors are to be mounted in the motor.

SpeedControl 1145 is also supplied in heat sink versions with vertical or horizontal ribs (LHS / SHS).

SpeedControl 1145 uses the newest technology within sensorless controlling of motors. However, the inverter must be adjusted to fit the specific motor profile in order to obtain the optimum performance and energy savings.
