Product Description:
The VACON0020-3L-0016-4-R02 is a low-voltage variable-frequency drive produced by Danfoss within the VACON 20 Low Voltage Drives series. It converts fixed-frequency mains power into a modulated output for precise speed regulation of induction motors used in conveyors, pumps, and mixers. The cabinet footprint measures 165 mm in both width and depth. The drive integrates power electronics, a control keypad, and I/O terminals, allowing it to fit into compact panels where installation space is limited.
The inverter delivers a continuous motor current of 16 A, while its nominal line current is 17.1 A, matching common feeder capacities. The required branch-protection fuse is rated at 25 A. Frequency commands have a resolution of 0.01 Hz, supporting precise speed control across the operating range. Power entry uses three-phase wiring, and the mains and motor connections each use a cable with a conductor arrangement of 3 × 6 + 6 mm². Regenerative energy is directed to an external braking resistor with a minimum resistance of 28 Ω. A transistorized digital output supplies 35 V at 50 mA, while an isolated relay switches 250 VAC at 3 A for direct connection to status lamps or contactors.
The housing is 370 mm tall and has a mass of 9 kg, supporting installation on a suitable backplate or DIN rail. Connected motors can have a maximum output rating of 7.5 kW. The drive can supply an overload current of 24 A during acceleration or brief load spikes without requiring continuous operation at that elevated level. The constant enclosure depth supports side-by-side placement of multiple units, while the gland plate provides an organized entry point for power conductors. Rapid deceleration transfers returned energy through the external resistor, helping prevent excessive voltage on the internal DC bus.
