Schneider ATV630D18N4 18.5KW Altivar Process 630 Variable Frequency Drives VFD

Schneider ATV630D18N4 is an 18.5kW inverter in the Altivar Process 630 series. The following is a detailed introduction:

Basic parameters

Rated power: 18.5kW (25hp) under standard load, 15kW (20hp) under heavy load.

Power supply voltage: three-phase AC380 - 480V, frequency 50 - 60Hz.

Current parameters: under standard load, the line current is 33.4A at 380V and 28.9A at 480V; under heavy load, 380V is 27.7A and 480V is 24.4A. The continuous output current is 39.2A (4kHz) for standard load and 31.7A (4kHz) for heavy load.

Dimensions: width 211mm, height 546mm, depth 232mm.

Protection level: IP21, in compliance with IEC 61800-5-1, IEC 60529 standards.

Features

Control function: It can drive synchronous and asynchronous motors, and supports multiple control modes, such as the optimized torque mode and standard constant torque mode of asynchronous motors, as well as the permanent magnet synchronous motor and synchronous reluctance motor control modes of synchronous motors, etc., which can achieve precise speed and torque control.

Communication capability: It supports multiple communication protocols such as Modbus TCP, Ethernet, Profibus, Devicenet, Profinet IO, etc. It is equipped with 3 RJ45 communication ports as standard, including 1 Ethernet port and 2 serial ports, which facilitates data interaction and integration with other devices.

Safety function: It has STO (safe torque off) function, reaching SIL3 safety level, which can quickly cut off the motor torque in an emergency to ensure the safety of personnel and equipment.

Input and output interface: There are 3 analog inputs, 2 analog outputs, 8 digital inputs and 3 relay outputs, which can be easily connected to external devices to realize various control and monitoring functions.

Application field

It is mainly used in process industries and utilities, such as chemical, pharmaceutical, environmental protection, water treatment and other industries. It can be used to drive various motor equipment such as pumps, fans, compressors, etc. to achieve precise control and energy-saving operation of motors.
