Product Description:

The VACON0020-3L-0001-4+EMC2+QPES is a three-phase AC variable-frequency drive supplied by Danfoss under the VACON 20 Low Voltage Drives series. It converts constant mains power into a variable-frequency output that lets machine builders adjust induction motor speed without mechanical dampers or gear changes. The device fits compact control panels where limited space and straightforward parameterization are required, and it serves typical automation tasks such as small conveyor sections, dosing pumps, and compact fans that demand precise speed regulation within fractional-kilowatt ranges.

Rated motor power reaches 0.37 kW, providing sufficient capacity for auxiliary axes. During steady operation, it draws a nominal input current of 2.2 A while delivering a continuous output current of 1.3 A to the motor terminals. A short-term overload ceiling of 2 A supports acceleration or brief process peaks, and speed can be adjusted in fine steps because the frequency resolution is 0.01 Hz. The digital output can source 35 V at 50 mA, and the relay contacts can switch 250 VAC at 3 A, enabling direct connections to contactors, indicator lamps, or PLC inputs. Electromagnetic compatibility is supported by an internal RFI filter, and the unit carries a C2 classification for installation on industrial low-voltage networks without supplementary suppression hardware.

Thermal management relies on an airflow rate of 10 m³/h through the heat sink to keep semiconductor temperatures within operating limits, and overcurrent protection is coordinated with a line fuse rated at 6 A. Power wiring uses three 1.5 mm² phase conductors and a 1.5 mm² protective conductor. The same conductor size applies to the motor leads, which may extend up to 30 m before additional filtering becomes necessary. For fault-level studies, the drive withstands prospective grid short-circuit currents up to a maximum of 50 kA. Its mass of 0.55 kg facilitates DIN-rail mounting in densely populated enclosures.
