LSIS H100 Series (HVAC) Drive – Efficient Control for Ventilation and Air Conditioning Systems

The LSIS H100 series drive, dedicated to HVAC applications, is an advanced device for smooth speed and torque control of motors in heating, ventilation, and air conditioning systems. Model LSLV0450H100-4 with a power of 45kW, supplied with 3x400V AC voltage and delivering an output voltage of 3x400V AC, is an optimal solution for a wide range of industrial applications. The device is characterized by its compact dimensions, allowing side-by-side mounting and efficient use of space inside control cabinets.

Functionality and characteristic features

The H100 drive offers a range of functions specifically tailored to the needs of HVAC systems, such as multi-motor control (MMC), work schedule programming, flow compensation, and gentle pipe filling. It is standardly equipped with an EMC filter of class C3, which minimizes electromagnetic interference, and a DC choke (from 30kW) stabilizing the supply voltage. Additionally, the LCD keyboard with dedicated buttons for HVAC applications makes operation and configuration easier. The USB port allows easy programming and software updates using a computer, and the RTC clock allows setting work schedules without the need for power backup.

Communication and compliance with standards

The drive provides versatile communication capabilities, including Modbus RTU/RS485 interface and Metasys N2 and Bacnet MS/TP protocols, enabling integration with building automation systems (BMS). The housing with IP20 protection degree ensures safe operation under normal operating conditions. The device design meets the requirements of the latest trends in advanced industrial applications and has certificates of compliance with applicable standards.
