Product Description:
175H7244 is a Danfoss VLT 3003 series industrial frequency converter, also known as an adjustable frequency drive. The converter has an input voltage rating of 380 / 400 / 415 Volts AC (three-phase). Operators can see the size and voltage rating for each VLT unit on start-up. Even when switched off, the unit can carry high voltage levels that pose a serious threat to human health. For VLT 3003 units, Danfoss specifies a wait time of 4 minutes after power switch off before operators should touch or handle the unit. Incorrect connections on the input or output sides can lead to equipment failure, injury or death. Therefore, only qualified personnel with relevant experience should be involved in installation and operations. The mains supply to the unit must be disconnected before repairs are attempted. Proper grounding is essential for safety of equipment and working personnel.
Different methods are available for stopping motors, including bus commands, local stop, and digital commands. 175H7244 is an IP54 rated VLT 3003 unit. Its rated output is 1.5 kilowatts. The converter is compatible with three-phase AC mains operated at 380 to 415 Volts AC. The maximum input current draw is 4.8 Amps. For continuous torque loads, the maximum supported motor size is 3 Horsepower, the nominal motor power is 2 Horsepower, the continuous output current is 4.1 Amps and the continuous output power is 2.9 kVA. For variable torque loads, the maximum supported motor size is 3 Horsepower, the nominal motor power is 2 Horsepower, the continuous output current is 4.1 Amps and the continuous output power is 2.9 kVA. Integrated thermal protection is available on the VLT 3003 series unit.
