Product Description:

The VACON0020-3L-0016-4 is a low-voltage AC drive manufactured by Danfoss as part of the VACON 20 Low Voltage Drives series. It adjusts the supply frequency and voltage fed to three-phase motors so automated equipment can match speed to process demand. A 165 mm width, 165 mm depth, and 370 mm height give the unit a square footprint that simplifies cabinet layout, and its enclosure weighs 9 kg. Mounting points are drilled for M6 hardware, allowing the drive to bolt directly to a backplate without extra brackets.

The power section delivers a continuous output current of 16 A and can operate motors rated up to 7.5 kW. Incoming mains current is limited to 17.1 A under nominal load, while short-term overloads are tolerated up to 24 A for applications that require brief torque surges. A recommended line fuse of 25 A provides branch-circuit protection consistent with these current values. Speed commands can be adjusted in increments as fine as 0.01 Hz, supporting tight process control at low and intermediate speeds. An internal 24 V auxiliary supply powers sensors or panel indicators. The transistorized digital output can switch 35 V at 50 mA for status signaling.

Control interfacing places minimal load on PLC cards because each digital input presents 10 kΩ of resistance. The drive can be located up to 50 m from the motor when shielded cables of the appropriate gauge are used, maintaining reliable pulse-width-modulated output without excessive voltage rise. For discrete signaling to external relays or contactors, the Form C relay inside the unit carries up to 250 VAC at 3 A. The available digital inputs support command and status connections from external control devices. Its relay output allows the drive to communicate operating conditions to other equipment without requiring a separate interface module. The supported motor-cable distance also provides flexibility when arranging the drive enclosure and connected machinery.
