Inverter LS Electric iS7 series SV0750iS7-4NODT SV0750IS7-4NODT

Modern drive control with LS Electric iS7 frequency inverter

The LS Electric iS7 series frequency inverter is an advanced solution for controlling electric motors, designed for both demanding industrial applications and precise control systems. The device combines high efficiency, reliability and intuitive operation, making it an ideal choice for professional installers and end users. Model SV0750iS7-4NODT, with a power of 7.5 kW, performs perfectly in a wide range of applications, from simple applications to advanced automation systems.

Functionality and capabilities

The iS7 series utilizes sophisticated control algorithms, guaranteeing precision and stability of machine operation. The LCD keyboard with a clear display in Polish facilitates configuration and monitoring of operating parameters. The ability to read up to four parameters online allows you to continuously monitor key data regarding the drive's operation. The inverter offers constant and variable torque operating modes, as well as control with encoder feedback, ensuring optimal adaptation to the specifics of a given application. A wide range of input/output expansion cards and PLC cards allows you to expand the functionality of the device and integrate it with other automation systems. The Easy Start function significantly simplifies the process of starting and configuring the inverter.

Construction and parameters

The LS Electric iS7 frequency inverter is characterized by a solid construction and high quality of workmanship. The integrated EMC filter compliant with IEC/EN 61800-3 (environment 1) ensures minimization of electromagnetic interference. The built-in choke in the DC circuit reduces the THD coefficient, and the insulation class F (155°C) guarantees reliable operation in harsh environmental conditions. Oversized power modules (IGBT) and capacitors ensure resistance to high overloads – even 150% of the rated current for 60 seconds and 200% for 3 seconds. The integrated braking module (up to 22kW) increases safety and control over the motor braking process. Double-lacquered printed circuit boards ensure stable operation even in harsh industrial conditions.

Applications

The versatility of the LS Electric iS7 frequency inverter means that it finds application in many industries:

• Industry: Control of pumps, fans, conveyor belts, mixers and other devices used in production processes.
• HVAC: Speed regulation of fans and pumps in heating, ventilation and air conditioning systems.
• Water and sewage: Control of water pumps and sewage pumping stations.
• Building automation: Control of blinds, shutters, gates and other building automation devices.
• Agricultural machinery: Control of motors in agricultural machinery such as irrigation pumps or feed mixers.
• Textile industry: Control of drives of textile machines such as winders or unwinders (thanks to the special WEB IS7 version).

Thanks to the possibility of expansion with communication cards (Profibus-DP, Ethernet, LonWorks, etc.), the inverter can be easily integrated with existing control and monitoring systems.
