Product Description:
The 178B1434 is an AC variable frequency drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. It converts fixed-frequency power into a modulated output that allows users to vary the speed of induction motors on conveyors, fans, and other industrial equipment. The drive supports straightforward panel mounting in applications where enclosure space is limited. Its regulated output also provides dependable motor torque across the usable operating range.
The drive delivers a continuous motor output of 0.75 kW, which is equivalent to 1.0 HP. This capacity suits small pumps, mixers, and conveyors that require limited shaft power. The input section accepts 380–480 V ±10% at 50/60 Hz mains power, while the inverter provides three-phase output to the connected motor. An internal rectifier converts the incoming AC supply to DC power, and the DC link stabilizes the energy before it reaches the inverter stage. Insulated-gate bipolar transistors then generate a pulse-width modulated waveform across the usable motor frequency range. The housing has an IP20 protection rating, making the drive finger-safe while requiring installation inside a suitable control cabinet.
The mechanical outline uses a Bookstyle format, providing a narrow width that allows several drives to be installed next to one another in a control enclosure. Operator interaction is handled through the built-in display (SLCP), which shows parameter codes and real-time operating values. This interface permits local access to motor settings, operating commands, and status information without requiring a separate display module. Conducted emissions on isolated supply networks are reduced by the embedded EN 55011 A1 (IT mains) RFI filter, which can reduce the need for additional filtering equipment. The drive is intended for process applications that use constant-torque operating profiles. It does not include an application option or a fieldbus card, and its circuit boards are uncoated for use in clean, temperature-controlled installations.
