Product Description:
The 131B2818 is a variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. The unit converts fixed three-phase mains power into a regulated output that allows controllers to adjust induction motor speed for conveyors, pumps, and other process equipment. By varying the output frequency and voltage, the drive can regulate motor operation in response to changing process requirements. Its compact dimensions support installation in switchgear enclosures where cabinet space is limited.
The drive provides a continuous mechanical output of 1.0 HP, which corresponds to a motor shaft power of 0.75 kW. The input section accepts an industrial supply ranging from 380–480 VAC and is designed for three-phase feeders, so single-phase derating is not required. To minimize conducted emissions, the drive includes an integrated EMC filter that attenuates high-frequency electrical noise at its terminals. The power stack is air-cooled, allowing heat to move away from the internal power components during operation. The control electronics are assembled on an uncoated printed circuit board intended for installation in a clean, controlled cabinet. Thermal and mechanical protection is rated IEC Class A, and the internal logic continuously monitors current and DC-bus voltage to detect operating conditions that could affect the connected motor or drive.
For panel integration, the housing carries an IP20 rating and uses standard cable entries that accommodate typical metric gland plates. The enclosure helps prevent accidental contact with internal components but must remain protected from water and excessive contamination by the surrounding cabinet. Functional safety is supported through the built-in Safe Stop feature, which removes motor torque without disconnecting the incoming mains supply. This function allows an external safety circuit to stop torque production while the drive remains connected to its power source. The drive is supplied without a local control panel, so operating data and parameters must be accessed through an external control interface. Its integrated monitoring functions continue to supervise the electrical conditions of the power stage during normal operation.
