Schneider ATV71H075N4S337 Altivar 71 Variable Frequency Drives VFD

Schneider ATV71H075N4S337 is a frequency converter in Schneider ATV71 series. The following is its related information:

Basic parameters

Adaptable motor power: 0.75kW (1hp).

Power supply voltage: 380 - 480V (-15% - +10%), 3 phases.

Input current: When the power supply voltage is 380V, the line current is 3.7A; when the power supply voltage is 480V, the line current is 3A.

Apparent power: Under the conditions of 380V, 3 phases, 0.75kW, the apparent power is 2.4kVA.

Overload capacity: It usually has an overload capacity of 150% for 60 seconds and 165% for 2 seconds. Please refer to the product manual for details.

Features

Control technology: Flux vector control technology is adopted to achieve high-precision speed and torque control, including control methods with or without sensors, which can accurately control torque and speed at extremely low speeds and has high dynamic performance.

Rich functions: It has more than 150 functions, such as PID controller, brake control for walking, lifting and rotary motion, etc. It also has speed or torque control, high set value resolution (1/32000), swing frequency function, etc.

Communication capability: It integrates Modbus and Canopen communication interfaces, which can easily communicate and network with other devices to achieve remote control, monitoring and parameter setting functions. It can also be controlled through mainstream communication networks, and the response to command sending and set value changes is very fast, both 2ms (±0.5ms).

Protection function: It has thermal protection, PTC, integrated thermal relay, peak voltage limitation and other protection functions for motors; it has overheating protection, software and hardware current limiting, etc. for inverters; it also has a safety interlocking function to prevent unintentional motor startup and ensure the safety of equipment and personnel.

Application scenarios: Suitable for a variety of industrial occasions, such as packaging and logistics machinery, process control machines, textile machinery, elevators, wood processing machinery, etc. For example, in some small packaging equipment, accurate speed control can be used to achieve accurate packaging of products; in small textile machinery, it can provide stable power output according to different process requirements.

Dimensions: Usually smaller in size, the specific dimensions may vary due to different installation methods and configurations, but roughly within the range of 100-200mm in length, width and height, which is convenient for installation in electrical control cabinets with limited space.

The ATV71 series has been replaced by the ATV930 series, but because the ATV71H075N4S337 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.
