Product Description:

The 175H1002 is an AC variable frequency drive manufactured by Danfoss and assigned to the VLT 3000 Variable Speed Drives series. It regulates motor operation by modulating output voltage and frequency. This allows a three-phase induction motor to match process demand and supports accurate speed control for pumps, fans, and material-handling equipment in automated plants.

At full load, the drive operates with an efficiency of 0.96, meaning only four percent of the input power is dissipated as heat. Digital control logic adjusts the fundamental output frequency in steps as fine as 0.05%, supporting precise closed-loop speed commands. The inverter can raise the fundamental output to a maximum of 500 Hz, so high-speed motors can be operated over a wide speed range. Its continuous power rating is 2.2 kW, which matches common 3 hp industrial motors. Motor leads may extend up to 150 m when shielded or 300 m when unshielded, giving more flexibility in drive-to-motor placement without exceeding EMC or voltage-drop limits.

The enclosure weighs 7.40 kg, which supports panel installation and provides room for cooling passages that remove internal power-stage losses. A programmable ramp time of up to 3600 s allows acceleration to be adjusted to reduce hydraulic or mechanical shocks in large-inertia systems. During maximum load, the unit releases only 130 W of heat, so standard forced-air cabinet ventilation is sufficient. Thermal motor protection combines an electronic algorithm with a DIN 44081 temperature sensor to help prevent winding overheating. Output transistors are rated for unlimited switching operations, and the carrier frequency is synchronized to the 50/60 Hz supply. The drive sustains stable operation in ambient temperatures up to 45 °C and can be stored safely at temperatures up to 70 °C.
