The Carlo Gavazzi HDMS2325G0V21C is an advanced single-phase dynamic soft starter designed for compressors and submersible pumps in demanding industrial and commercial motor control applications. As part of the intelligent Carlo Gavazzi HDMS series, it provides controlled motor acceleration while reducing electrical inrush current, mechanical stress and wear on connected equipment.
This compact soft starter integrates advanced motor control technology with an internal bypass relay for improved efficiency and reduced heat generation during normal operation. The HDMS series also includes NFC communication and Modbus RTU connectivity, enabling simplified setup, diagnostics and seamless integration into modern automation systems.
With a rated operational current of 25 A, an operating voltage range of 110–230 V AC, and support for motors up to approximately 3.7 kW at 230 V, the HDMS2325G0V21C is ideal for HVAC compressors, refrigeration systems, water pumps and industrial automation systems requiring reliable soft starting and compact DIN rail installation.
Soft starters such as the Carlo Gavazzi HDMS2325G0V21C 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.
