LSIS S100 Series Inverter – Precise Control and Reliability in Every Application

The LSIS S100 series inverter is a general-purpose frequency converter designed to control three-phase motors powered by 3x400V AC voltage. The device combines advanced control functions, a solid construction, and ease of use, making it an ideal solution for both professional installers and end-users. Model LV0110S100-4EXFNS with a power of 11kW provides optimal performance in a wide range of industrial and commercial applications.

Functionality and Application

The S100 frequency converter offers flexible control options, including sensorless vector control with constant and variable torque. This allows for precise adjustment of engine operating parameters to specific application requirements, ensuring optimal efficiency and energy savings. Thanks to the built-in PLC functions, it is possible to program simple control sequences, eliminating the need for external controllers in many cases. The inverter finds application in various applications, such as:

• HVAC systems (heating, ventilation, air conditioning)
• Pumps and fans
• Packaging machines
• Cranes and hoists
• Tower cranes
• Applications requiring precise torque control

Construction and Characteristic Features

The LSIS S100 series inverter is distinguished by a solid construction and a high degree of protection. The IP66 enclosure provides resistance to dust and water jets, allowing the device to be mounted in harsh environmental conditions. The built-in EMC C3 filter minimizes electromagnetic interference, ensuring compatibility with other devices in the installation. Additional features include:

• LED keyboard for easy configuration and monitoring of operating parameters.
• Possibility of side-by-side installation – saving space in the switchgear cabinet.
• Modbus RTU/RS485 communication – integration with automation systems.
• Built-in STO (Safe Torque Off) input compliant with EN-60204-1 (category 0), EN-954-1 (safety category 3), EN-61508 (SIL2) and EN-ISO-13849-1 standards – ensuring safe shutdown of the device.
• Possibility of obtaining 200% of rated torque at 0.5Hz frequency - ideal for applications with high load inertia.
• Fast RS485 communication (max. 115kbps) and peer-to-peer P2P communication between inverters.

Thanks to the use of modern Dual CPU processors with high performance (DSP 60MISP and MCU 48MHz), the inverter provides fast information processing time and precise engine control. The improved vector control algorithm allows for smooth start-up and precise setting of torque limits.
