LSIS S100 series inverter. Power supply 3x400V AC, output 3x400V AC. LSLV0370 S100-4EOFNM, 37kW LV0370S100-4COFDS

LSIS S100 Series Inverter – Precise Control and Efficiency

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 with a compact design, making it an ideal solution for both professional installers and end-users. Model LSLV0370S100-4COFDS with a power of 37kW ensures reliable operation in a wide range of industrial applications.

Functionality and application

The S100 inverter offers both scalar U/f control and sensorless vector control, allowing for optimization of motor operation depending on the specifics of the load. The ability to obtain 200% starting torque at a low frequency (0.5Hz) makes it an excellent choice for machines with high inertia. The built-in PID regulator enables precise control of process parameters, such as pressure or temperature, eliminating the need for external regulators.

The device finds application in various applications, including:

• Cranes and hoists
• Tower cranes
• Pumps and fans
• Packaging machines
• Production lines

Safety and communication

Safety of use is a priority. The inverter is equipped with a Safety Stop safety relay compliant with EN-60204-1 (category 0), EN-954-1 (safety category 3), EN-61508 (SIL2) and EN-ISO-13849-1 standards. Additionally, the built-in EMC C3 filter minimizes electromagnetic interference.

Modbus RTU/RS485 communication enables integration of the inverter with automation and monitoring systems. Peer-to-peer (P2P) communication between inverters facilitates the creation of multi-drive systems and sharing of I/O resources. The built-in simple PLC functions allow for the implementation of basic control sequences without the need for an external controller.

Design and characteristics

The inverter housing has an IP20 protection class, which provides protection against touch and access to internal components. Compact dimensions and the ability to mount them side by side allow for optimal use of space in control cabinets. Standard equipment includes an LED keypad and an LCD display (in models with a power of 30kW and higher), making configuration and monitoring of device parameters easier. DC choke is built into the device which improves the power factor and THDI.
