Schneider ATV71HD18N4S337 Altivar 71 Variable Frequency Drives VFD

Schneider ATV71HD18N4S337 is a frequency converter in Schneider ATV71 series. The specific information is as follows:

Applicable motor power: 18.5kW (25hp), can be used to drive medium-power AC motors to meet the power requirements of equipment such as small fans and water pumps.

Power supply voltage: The applicable range is 380 - 480V (-15% - +10%), 3 phases, which can adapt to the power supply conditions of most industrial occasions.

Current parameters: When the power supply voltage is 380V, the line current is 45.5A; when the power supply voltage is 480V, the line current is 37.5A.

Functional features: Belongs to the ATV71 series, using flux vector control technology, which can achieve high-precision speed and torque control. It has more than 150 functions, including PID controller, brake control for walking, lifting and slewing motion, etc. It integrates a Class A EMC filter to reduce electromagnetic interference to the power grid and improve its own anti-interference ability. It also integrates Modbus and Canopen communication interfaces to facilitate communication and networking with other devices to achieve remote control, monitoring and parameter setting functions.

Dimensions: 230mm×400mm×213mm.

Application scenarios: Suitable for vertical lifting, translation and rotation motion control of lifting equipment such as cranes, overhead cranes, gantries, etc., as well as drive control of high-inertia, unbalanced mechanical equipment such as centrifuges, mixers, beam pumps, presses, etc.

The ATV71 series has been replaced by the ATV930 series, but because the ATV71HD18N4S337 was once widely used in the industrial field, there are still a certain number of them in operation on the market, and there are also related maintenance services and spare parts supply.
