Product Description:

The VACONX4C20030C is an AC variable frequency drive produced by Danfoss in the Low Voltage VACON X Drives series. It converts a fixed three-phase supply into a variable waveform so that a PLC can command the speed and torque of compact induction motors used in conveyors, material-handling stations, and building services. Designed for decentralized mounting, the enclosure supports direct wall installation and integrates the motor protection, monitoring, and energy-conversion functions required for dependable industrial automation.

The drive accepts a three-phase AC mains input and delivers up to 1.5 kW of continuous output power, which is equivalent to 2 HP at the motor shaft. At nominal load, the inverter draws 6.8 A, a value used when selecting branch-circuit protection and cabling. For transient torque demands, the power stage tolerates an overload of 150% for 60 seconds, allowing equipment to accelerate or clear jams without nuisance trips. Heat produced by the switching devices is removed through natural convection, eliminating internal fans and reducing maintenance requirements. This cooling method requires free airflow past the ribbed housing. It is suitable for installations where dust-laden air could shorten the service life of forced-air components.

Protective thresholds disconnect the converter when the DC link rises to 406 VDC or drops to 199 VDC, and dynamic braking is triggered at 388 VDC to keep the bus within its operating limits during rapid deceleration. The chassis withstands continuous vibration up to 5 g, has an acoustic output of 80 dBA at a distance of one meter, and can operate at altitudes up to 1,000 meters. The unit measures 165 mm wide, 155 mm deep, and 241 mm high, while its weight of 3.85 kg supports installation in compact service panels with enough surrounding clearance for natural-convection cooling.
