Product Description:

The VACON0020-3L-0023-4-R02+EMC2 is an AC variable-frequency drive manufactured by Danfoss within the VACON 20 Low Voltage Drives series. It controls three-phase motors in conveyor, pump, and fan applications by converting constant-frequency mains power into a modulated output with frequency and voltage that can be adjusted on demand. Its compact dimensions and panel-mounted design allow the drive to fit easily into distributed control panels throughout automated installations.

The drive supports a motor rating of 11 kW and delivers a continuous phase current of 23 A to the motor terminals. It draws a nominal line current of 25.5 A, so upstream protection devices must be sized accordingly. The power stage has a preset switching frequency of 4 kHz, balancing acoustic noise with semiconductor losses. The IP21 enclosure protects internal boards from solid objects larger than 12 mm and limited exposure to dripping water. Remote-control terminals offer a digital input resistance of 10 kΩ and a voltage input impedance of 250 kΩ, ensuring that low-power PLC outputs are not overloaded. The MI4 frame size uses a recommended mains cable cross-section of 3 × 6 + 6 mm² and a fuse rating of 25 A, providing clear requirements for cabinet wiring. Motor cables may run up to 50 m without additional output chokes.

The drive provides a short-term overload current of 34.5 A, supplying additional torque during startup and momentary load spikes. Thermal management relies on an internal fan that moves 45 m³/h of cooling air across the heat sink to dissipate switching losses. Conducted and radiated emissions comply with industrial limits under the C2 EMC category, so additional line filters are typically unnecessary. The unit has a transport mass of 9 kg, which makes it easier to handle when positioning it inside a compact control panel. Its compact enclosure also helps preserve space around neighboring control components and cable routes.
