Product Description:
The VACON0020-3L-0004-4-X Frequency Converter is produced by Danfoss and used in industrial automation. It belongs to the VACON® 20 X product family. The unit is designed for a three-phase AC input connection. It accepts a supply voltage range from 380 to 480 volts AC and provides a rated output of 3.3 amperes.
The VACON0020-3L-0004-4-X frequency converter incorporates an integrated brake chopper to manage braking energy effectively. A main switch is included to support operational safety and simplify system control. The assembly is housed in an MU2 frame size. Its physical dimensions measure 170 millimeters in width, 295 millimeters in height, and 154 millimeters in depth. The drive weighs 3.4 kilograms net, with a gross shipping weight ranging from 3.9 to 4.4 kilograms. The total enclosure volume is specified as 20.631 cubic decimeters. The VACON0020-3L-0004-4-X frequency converter complies with EMC2 classification for industrial and commercial use. It is certified to UL, CE, C-Tick, and KC standards to meet international regulatory requirements. The unit is supplied with Multipurpose System Software. It enables configuration without predefined application packages. This version does not include an option board interface or integrated keypad to provide a straightforward setup for defined applications.
The terminal arrangement of the VACON0020-3L-0004-4-X frequency converter is specified as Term B Cable Gland without a dedicated brake terminal. The frequency reference is set to 50 hertz, with measurement values expressed in metric units. The frequency converter is rated for continuous operation between -10 °C and +40 °C at full load. For ambient conditions above +40 °C, the unit can be used up to +50 °C with a derated output capacity. The converter may be stored at temperatures from -40 °C to +70 °C without damage when out of service.
Frequently Asked Questions about VACON0020-3L-0004-4-X:
Q: How does the integrated brake chopper function in VACON0020-3L-0004-4-X?
A: The internal brake chopper dissipates regenerative energy from motor deceleration as heat. This protects the DC bus from overvoltage and enables controlled, rapid stopping of high-inertia loads.
Q: What are the implications of the EMC2 classification for VACON0020-3L-0004-4-X?
A: EMC2 classification signifies a high level of electromagnetic compatibility for industrial environments. This reduces the risk of interference with sensitive nearby equipment, simplifying panel design.
Q: Why is there no option board interface on the VACON0020-3L-0004-4-X?
A: Omitting the option board interface streamlines the design for cost-effective, fixed-function applications. This makes the drive suitable for simple pump, fan, or conveyor control without expanded I/O.
Q: How does the MU2 frame size impact VACON0020-3L-0004-4-X panel layout?
A: The compact MU2 frame size allows for high-density mounting within control enclosures. The 154mm depth and 3.4kg weight minimize the required panel space and structural support.
Q: What is the purpose of the main switch on the VACON0020-3L-0004-4-X unit?
A: The integrated main switch provides a reliable means for functional isolation and safety during maintenance. This eliminates the need for an external disconnect device for many basic installations.
