Product Description:

The 131B0087 is a variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. It is designed for installation in automation panels, where it regulates the speed and torque of a connected motor. By adjusting motor operation to process demand, the drive can reduce unnecessary energy consumption in conveyors, pumps, fans, and other industrial equipment. Its FC 302 platform supports general automation applications that require controlled acceleration, deceleration, and continuous speed regulation.

This model accepts three-phase power across an input range of 380-500 VAC. Its rated motor output is 1.5 kW, which corresponds to 2.0 HP. The chassis has an IP20 enclosure rating, providing protection against accidental contact with internal electrical parts but not against water. Installation inside a suitable control cabinet is therefore required when the surrounding area demands greater protection from moisture, dust, or debris. The normal cabinet-mount configuration accommodates A, B, and C frames, while the standard enclosure depth supports organized placement with other panel-mounted control components.

An integrated RFI filter limits conducted electrical interference that could otherwise travel from the drive into the supply network. Regenerative energy produced during motor deceleration is managed by a brake chopper, which directs excess DC-bus energy to an external braking resistor. Standard cable entries provide paths for the mains, motor, and control wiring without requiring a special entry arrangement. The printed circuit boards are not coated, making the drive best suited to clean, temperature-controlled cabinets where condensation and corrosive contaminants are controlled. The unit has no local control panel, so operating commands, parameter changes, and status monitoring must be handled through the available remote or network interfaces. Its standard language pack supports multilingual parameter access through a compatible external interface.
