Product Description:

The 175H8858 is an AC variable speed drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. Installed between the power bus and an induction motor, it converts fixed-frequency mains into adjustable voltage and frequency. That lets conveyors, pumps, and fans follow speed commands from a PLC or local control loop with stable regulation.

The power stage tolerates line variation within ±10% of nominal voltage, which helps prevent nuisance trips during mains sag or swell. With a matched motor, the inverter supports a continuous shaft rating of 2.2 kW. Its rated output current is 4.8 A. Closed-loop vector control tracks commanded speed against the motor’s synchronous point, and the carrier can be tuned around a base frequency of 60 Hz to reduce audible noise and unnecessary harmonic loss.

Upstream protection is provided by a 16 A pre-fuse that matches the drive’s semiconductor limits. Field wiring accepts conductors up to 2.5 mm², for flexible panel wiring without excessive force on the terminals. Ramp 1 can be programmed to a rise time of 5 s, reducing shock to couplings and loads. The digital logic allows switching on the enable input only once per minute to limit thermal stress during repeated starts.

Wake Industrial offers a 1-year warranty on every unit. Same-day shipping is available for time-critical orders, and quotations remain valid for 30 days to simplify internal approval cycles.
