175H1695 Danfoss

Product Description:

The 175H1695 is a variable frequency drive manufactured by Danfoss for the VLT 3000 Variable Speed Drives series. It converts fixed-frequency three-phase mains into a regulated output so that induction motors can be started smoothly, run at adjustable speed, and matched to process requirements. In automated plants the unit acts as the interface between the electrical supply and mechanical equipment, providing torque control, acceleration ramps, and built-in protection features that minimize electrical stress on both the motor and the distribution network.

The drive accepts a three-phase input of 3 x 380/400/415 V with a ±10 % tolerance. Within this range it delivers a continuous mechanical output of 1.1 kW and supplies the motor with a rated current of 2.8 A. Apparent input demand reaches 2.0 kVA, a figure used when sizing feeders and contactors. Line compatibility spans the universal industrial standard of 50/60 Hz, so no hardware changes are required when moving the unit between regions. Heat produced during operation is 60 W at full load, and the internal monitoring firmware records this value for thermal protection.

During transient load peaks the inverter can supply 3.1 A for up to 60 seconds, preventing nuisance trips when accelerating heavy machinery. Upstream circuit safety is covered by a recommended 16 A gG pre-fuse that clears faults without oversizing conductors. Installation distance is flexible because screened motor leads may run to 150 m, while unscreened leads can extend to 300 m where electromagnetic emission limits allow. Full load performance is maintained at ambient temperatures up to 40 °C; above this point derating curves reduce output to keep silicon devices within safe junction limits.
