LSIS H100 Series (HVAC) Frequency Inverter – Precise Drive Control

The LSIS H100 series (HVAC) frequency inverter is a variable frequency drive designed for advanced control of electric motors in HVAC (heating, ventilation, and air conditioning) applications. The device operates on a 3x400V AC system, both input and output, offering a power of 15kW. Model LSLV0150H100-4 is a solid solution for both professional installers and end-users looking for reliable motor speed control.

Functionality and Application

This inverter has been designed with the specific requirements of HVAC systems in mind. Vector control provides high precision regulation, which translates to optimal efficiency and energy savings. Built-in application macros and functions dedicated to HVAC simplify configuration and adaptation of the device to specific needs. The ability to program schedules using the RTC clock allows for process automation and reduced operating costs.

Installation and Communication Comfort

Compact dimensions (0.21 x 0.29 x 0.18 m) allow for easy installation even in limited spaces, and the ability to mount them side by side increases design flexibility. The inverter is equipped with an HVAC LCD keypad for easy operation and a USB port for communication with a PC. Support for Modbus RTU/RS485, Metasys N2 and Bacnet MS/TP communication protocols enables integration with building automation systems and device performance monitoring. Additionally, the EMC C3 filter minimizes electromagnetic interference, and the DC circuit choke (from 30kW) stabilizes the supply voltage. The housing with IP20 protection degree protects against access to dangerous internal elements.
