Product Description:
The VACON0100-3L-0031-5-FLOW-R02 is an AC variable-frequency drive produced by Danfoss for the VACON 100 Industrial Drives series. In automated plants, this unit modulates three-phase power so that induction or permanent-magnet motors run at commanded speed and torque levels without mechanical throttling. By matching motor demand to the process load, the drive improves energy efficiency and limits equipment stress. It is intended for pumps, fans, and other flow-related machinery where adjustable speed control supports precise process regulation.
A three-phase input rated at 380–500 VAC feeds the converter stage. In the IH category, the inverter supplies 23 A continuously, while the IL setting allows 31 A. These continuous limits are supported by a peak output of 46 A for two seconds to handle acceleration or transient overloads. The IP21 / Type 1 enclosure permits installation inside switchrooms without an additional housing. When connected to 480 V mains, the IL profile supports motors with an output of up to 20 HP, while the IH profile supports machines with an output of up to 15 HP. Its IEC 61800-3 C2 EMC emissions classification permits operation on industrial networks where conducted electrical noise is controlled.
The MR5 frame measures 214 mm deep, 144 mm wide, and 419 mm high, allowing the required cabinet and airflow clearances to be calculated accurately. With a mass of 10 kg, the unit can be installed without specialized lifting equipment. At 400 V, the heavy-duty current limit corresponds to a motor output of 11 kW, whereas the normal-duty setting extends the motor capacity to 15 kW. The two duty profiles accommodate both constant-torque and variable-torque loads in flow-control applications. The enclosure dimensions also leave space for power, motor, and control wiring within crowded control cabinets.
