LSIS H100 Series Inverter – Optimization for HVAC Systems

The LSIS H100 series inverter is a modern solution designed to control motors in HVAC (heating, ventilation, and air conditioning) applications. Model LSLV0055H100-4, with a power of 5.5kW and a power supply of 3x400V AC, provides efficient and precise control of pumps, fans, and other devices used in heating and cooling systems. The device is characterized by a compact design and a wide range of functions dedicated to the specific needs of the HVAC industry.

Construction and functionality

This three-phase inverter has been designed with ease of installation and use in mind. It is equipped with a built-in EMC filter of class C3, which minimizes electromagnetic interference, ensuring stable system operation. For models with higher power (from 30kW), a choke in the DC circuit is used, which improves the power factor and reduces harmonic current. An intuitive HVAC LCD keypad facilitates parameter configuration and device status monitoring. Additionally, a USB port allows connection to a computer for advanced diagnostics and programming. A built-in RTC clock allows programming work schedules, which increases the energy efficiency of the system. The housing with a protection degree of IP20 provides basic protection against external factors.

Communication and control

The LSIS H100 inverter offers a wide range of communication possibilities, making it an ideal solution for integration with building automation systems. It supports Modbus RTU/RS485, Metasys N2, and Bacnet MS/TP protocols, enabling seamless data exchange with other devices on the network. Vector control is used, which provides high precision in regulating the motor speed, even under varying loads. Application macros dedicated to specific HVAC applications are also available, such as pump or fan control.
