Inverter series IS7 versatile, professional, and advanced algorithms with 375kW power supply of 3x400VAC SV3750IS7-4SO

LS IS7 Universal Drive – Power and Versatility for Industry

This advanced drive from the iS7 series is a solution dedicated to demanding industrial applications. The device is distinguished by its high functionality, wide range of applications, and advanced control algorithms, ensuring precision and reliability of machine operation. The SV3750IS7-4SO model with a power of 375 kW, powered by a 3x400V voltage, is designed to control motors with a current of 731A.

Construction and Configuration Options

iS7 drives offer flexibility in adapting to specific needs. They are standardly equipped with 8 digital inputs, a 4-20mA current analog input, a -10 ~+10V voltage analog input, and 2 analog outputs (voltage and current) and 4 multifunctional outputs. Communication is via a built-in RS485 / Modbus RTU interface. Numerous expansion cards provide the ability to expand functionality – PLC, encoder, additional inputs/outputs, and communication (Profibus-DP, Ethernet, LonWorks, DeviceNet, CanOpen, R-Net, CC-Link, profinet).

It is worth noting the built-in Class A anti-interference filter (up to 22kW power) and the DC choke limiting harmonic interference – these elements affect the stability of operation and extend the life of the device. For power above 22kW, external filters dedicated to the specific parameters of the drive are available.

Application and Benefits

The LS iS7 drive performs well in a wide spectrum of industrial applications: from controlling pumps and fans to advanced technological systems. The ability to control constant- and variable-torque and support encoders allows for precise matching to the load characteristics. This makes it possible to optimally utilize energy and increase the efficiency of production processes.

• Versatility: A wide power range (from 0.75kW to 375kW) allows for use in various applications.
• Advanced Control: Vector control, constant- and variable-torque, provides precision and dynamic operation.
• Flexibility: The ability to expand functionality with expansion cards.
• Protection: Built-in protections protect the drive and connected devices from damage.
• Compatibility: Compliance with EMC standards ensures a minimal level of electromagnetic interference.
• Easy Integration: The built-in RS485 / Modbus RTU communication interface facilitates integration with industrial automation systems.
• Durability: Oversized power modules (IGBT) and capacitors ensure reliable operation even under high overloads (150% In for 60 seconds, 200% In for 3 seconds).

Please note that the control panel is not standard equipment for the IS7 drive and is available as a separate accessory.
