Product Description:
The FC-301P18KT4134L2691 is a variable frequency drive from Danfoss that belongs to the VLT FC 301 Automation Drives series. As an AC inverter, it converts fixed three-phase mains power into a modulated output that allows controllers to regulate induction motor speed and torque. This regulated output supports pumps, conveyors, and other process equipment used in industrial automation.
The drive delivers a continuous mechanical output of 18.5 kW, which is equivalent to 25 HP, and supports a rated motor current of 34 A at 460 V. On the line side, it draws 31 A, and its apparent power reaches 31.9 kVA, so upstream circuit protection and cabling must accommodate this demand. Its conversion efficiency is 0.98, meaning that approximately two percent of the input energy is lost as heat under nominal operating conditions. The unit accepts a three-phase input ranging from 380 to 480 VAC. It supports networks with a maximum phase imbalance of 3.0 percent. The drive is part of the VLT AutomationDrive FC product group and uses the internal series identifier 301.
Thermal dissipation under nominal operating conditions is estimated at 444 W, so cabinet airflow must remove this heat load. During acceleration or transient load spikes, the inverter can supply an overload current of 54.4 A. The control algorithm sustains 160 percent torque for 60 seconds before returning to the continuous operating rating. Power quality is supported by a displacement power factor greater than 0.98, while the true power factor remains at least 0.9 under rated load. The drive operates with a supply frequency of 50/60 Hz ±5 percent. Motor leads may extend up to 150 m when shielded or up to 300 m when unshielded, allowing the controller to be mounted remotely from the connected motor.
