Product Description:
The 175H7249 is an AC variable frequency drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. The unit synthesizes a variable-frequency, variable-voltage output that allows automated plant controllers to adjust induction motor speed without mechanical throttling. This control method makes the drive suitable for conveyors, mixers, and pump skids that require consistent process control under changing load conditions.
The drive operates with a conversion efficiency of 0.96, limiting the amount of supplied energy that becomes heat during normal operation. Its IP54 enclosure protects the internal electronics from dust and water splashes, allowing installation outside sealed panels when surrounding conditions remain within the permitted operating limits. The line supply current reaches 7.0 A at nominal load, and a 16 A upstream fuse protects the supply conductors by interrupting excessive fault current. On the motor side, the inverter delivers 5.6 A of output current and provides a continuous apparent output of 4.0 kVA. The drive has a motor power rating of 2.2 kW, making it suitable for compatible induction motors within that power range. An integrated brake transistor and resistor network dissipates regenerated energy during rapid deceleration, helping control the DC bus voltage when an attached load slows down.
Short-term loading is supported by an overload current limit of 9.0 A, allowing the drive to accelerate higher-inertia loads for up to one minute while providing as much as 6.4 kVA. Internal power losses are limited to 130 W, which must be considered when arranging enclosure ventilation and maintaining the required operating temperature. Power and control leads terminate in spring-clamp terminals sized for 2.5 mm² copper conductors, providing secure wiring connections without oversized cable hardware. The drive can supply motors located up to 300 m away, while installations using shielded cable for electromagnetic compatibility are limited to 150 m. Its total mass is 11.0 kg, which supports manageable transport, positioning, and mounting during installation. The available cable distances allow the converter to remain near the plant power distribution point while the connected motor operates farther away on the machine.
