Product Description:

The VACONX5C40075C09 is a low-voltage AC variable frequency drive released by Danfoss within the Low Voltage VACON X Drives series. It modulates the power supplied to three-phase induction motors, allowing machine builders to adjust shaft speed without mechanical gearing or throttling. By converting fixed-frequency mains power into a regulated output, the unit provides a compact, field-mounted controller for pumps, conveyors, and mixers operating in demanding industrial environments. Its variable-speed control can also help equipment respond efficiently to changing process demands.

The power section accepts a 380–460 VAC three-phase input, matching common plant distribution networks. Internally, the inverter synthesizes a motor signal across a frequency range of 0.1–400 Hz, providing control from crawl speed to the motor’s rated speed. Pulse-width modulation operates at a carrier frequency of 1–16 kHz; selecting a higher carrier frequency reduces audible motor noise while increasing switching losses. For constant-torque applications, the drive can deliver a normal-duty output current of 11 A. This current capacity supports a rated motor output of 5.5 kW. Thermal sensors and software limits work together to control junction temperatures and reduce nuisance trips under fluctuating load conditions.

When an operating cycle requires intermittent overload capacity, the heavy-duty rating supports a motor output of 4 kW for the permitted duty period before the drive returns to its continuous operating limits. The housing has an IP66 rating, preventing dust ingress and protecting the internal electronics against powerful water jets. This protection allows the drive to be installed on washdown lines without a separate enclosure when installation requirements permit. Reliable operation is supported across an ambient temperature range of -10 to +40 °C, allowing installation outdoors or in unconditioned rooms within the stated limits. The drive measures 221 × 306 × 166 mm and weighs 6.35 kg, making it suitable for compact mounting arrangements without excessive structural reinforcement. Its T1 frame size provides consistent cable entry positions, while the lack of option card slots helps minimize enclosure depth.
