Product Description:
The VACON0020-3L-0005-4 +EMC2+QPES+DLFI Drive efficiently manages energy with a modest input requirement of 5 amperes only. This Danfoss module three phase AC input ensures smooth and balanced operation. It adheres to EMC Class 2 standards and it can be confidently integrated into sensitive industrial automation setups without risk of interference.
The VACON0020-3L-0005-4 +EMC2+QPES+DLFI drive protective housing around it is rated at IP 20 which offers basic protection from accidental touch with fingers but is not sealed against dust or water. The software chosen for communication and control is the version tailored to the Vacon0020 product line which defines how external systems can interact with the drive. It has an internal circuit capable of dissipating excess energy generated during motor deceleration which prevents overvoltage on the DC bus by diverting energy into a resistor. It is capable of delivering a steady and uninterrupted current of 38 amperes under normal operating conditions. It operates from a three phase power supply in the range of 380 to 480 volts AC which allows it to be compatible with common industrial low voltage grids. Its reference operating frequency is set to 50 Hz which aligns with the standard grid frequency in most parts of the world.
The VACON0020-3L-0005-4 +EMC2+QPES+DLFI drive is 90 mm wide, 195 mm high and 102 mm deep which shows how much panel space is needed for installation. It comes with a protective earth plate kit which ensures a reliable grounding connection and improves safety and reduces EMI in the system. It is designed as a modular unit intended for integration into a larger system and it is not a standalone boxed solution but it is designed to slot into structured panels.
Frequently Asked Questions about VACON0020-3L-0005-4 +EMC2+QPES+DLFI:
Q: What is the impact of the 5A input current on system power requirements?
A: The 5A input current reflects the nominal energy draw under typical operational conditions, making it easier to size upstream fuses and breakers. This helps optimize energy efficiency without overloading the system.
Q: How does the IP20 enclosure rating affect installation?
A: The IP20 rating provides basic protection, allowing the drive to be safely installed in controlled environments where dust and moisture are minimal. It is not suitable for outdoor or harsh environments.
Q: What role does the brake chopper play in motor deceleration?
A: The brake chopper prevents overvoltage on the drive's DC bus during rapid motor deceleration by dissipating excess energy. This ensures smooth operation and protects the drive from electrical stress.
Q: How does the 38A continuous current affect motor selection?
A: The 38A continuous current rating indicates the maximum steady current the drive can provide to the motor without overheating. It allows the drive to support larger motors or heavy-duty applications without risking system failure.
Q: Why is a three-phase AC input necessary for this VACON0020-3L-0005-4 +EMC2+QPES+DLFI drive?
A: A three-phase AC input ensures a more stable and efficient power supply compared to single-phase power. It helps reduce motor vibrations and increases the overall energy efficiency of the system.
