178B8580 by Danfoss

Danfoss supplies the 178B8580 as a low-voltage AC drive in the VLT 2800 Low Voltage Drives series. It regulates induction motor speed and torque in conveyors, mixers, and pumps so process equipment can respond to changing demand instead of running at a fixed speed. The unit is intended for industrial automation where compact motor control and straightforward local operation are preferred.

The drive provides a continuous output of 1.5 kW and accepts input power from 380-480 V ±10% 50/60 Hz. It is connected to three-phase mains, so it fits common industrial power systems without additional phase conversion equipment. The enclosure is rated IP20, which makes it suitable for installation inside control cabinets where protection against accidental finger contact is needed. Its compact book-style housing helps conserve panel width in dense multi-drive layouts. No RFI filter is fitted, so applications with stricter electromagnetic compatibility limits require an external filter. The model is also supplied without a fieldbus module, so control signals are handled through local interfaces and hard-wired I/O.

Peak motor output corresponds to 2.0 HP, which provides a familiar reference when matching the drive to motor nameplate data. Parameter changes are made through a built-in display (SLCP), so basic setup can be completed on the unit itself without a removable keypad. The drive is the standard with brake version, which means it includes an internal brake transistor for handling deceleration energy in light-inertia applications. The boards are supplied with coating to improve resistance to airborne moisture and process vapors in enclosed industrial environments. The unit is intended for process-duty use, and its local control approach suits installations that rely on direct wiring rather than network-based control.
