Product Description:

The VACONX4C50150C is a low-voltage AC variable frequency drive produced by Danfoss for the Low Voltage VACON X Drives series. The unit modulates motor speed by converting fixed mains frequency into a controlled output waveform, allowing conveyors, pumps, and fans to match process demands without mechanical throttling. Its sealed construction allows the drive to be mounted directly on the production floor, reducing cabinet space and shortening motor cable runs in industrial automation layouts.

Power electronics inside the drive accept a 575 Vac supply delivered through a three-phase feeder. The control circuit removes power if the DC bus falls below the undervoltage point of 497 Vdc or rises above the overvoltage limit of 1017 Vdc; dynamic braking engages once the bus reaches 970 Vdc. In heavy-duty service, the inverter provides 7.5 kW of mechanical output while carrying 11 A, supporting high starting torque and cyclic loads. For lighter, continuous applications, it is rated at 11 kW with an armature current of 17 A, providing higher horsepower when thermal cycling is moderate. These selectable duty profiles allow one frame size to cover multiple motor ratings, while the trip thresholds protect semiconductor components from unstable line conditions.

The housing achieves IP66 ingress protection, preventing dust or water jets from reaching the circuitry. A forced-air blower channels exhaust through the chassis, which measures 273 mm wide, 201 mm deep, and 442 mm high, while limiting sound emissions to 80 dBA. With a mass of 13.38 kg, the drive can be secured to a suitable wall bracket, and its compact outline allows placement close to machinery when panel space is limited. The enclosure dimensions also leave clearance for conduit bends and preserve the airflow paths required by the internal heat sink. Proper mounting clearance helps the forced-air cooling system move heat away from the power electronics during sustained operation.
