The Carlo Gavazzi HDMS2337G0V21C is a high-performance single-phase dynamic soft starter designed specifically for compressors and submersible pumps in demanding industrial and commercial motor control applications. As part of the intelligent Carlo Gavazzi HDMS series, it delivers smooth motor acceleration while reducing electrical inrush current, mechanical stress and wear on connected equipment.
This advanced soft starter integrates intelligent motor control functionality with an internal bypass relay for improved operational efficiency and reduced heat generation during continuous operation. The HDMS series also incorporates NFC communication and Modbus RTU connectivity, enabling simplified setup, diagnostics and seamless integration into modern automation systems.
With a rated operational current of 37 A, an operating voltage range of 110–230 V AC, and support for motors up to approximately 5.5 kW at 230 V, the HDMS2337G0V21C is ideal for HVAC compressors, refrigeration systems, industrial pumping equipment and demanding commercial motor control applications requiring reliable soft starting performance and compact DIN rail installation.
Soft starters such as the Carlo Gavazzi HDMS2337G0V21C gradually ramp motor voltage during startup, helping reduce electrical peak current and minimising mechanical shock to compressors, pumps and associated drive systems. This controlled startup process improves operational reliability while helping extend motor service life.
The HDMS range is trusted by industrial engineers, HVAC specialists and automation professionals because of its compact DIN rail design, integrated bypass functionality and intelligent communication capabilities. NFC and Modbus connectivity simplify commissioning, monitoring and diagnostics in modern control systems.
