Carlo Gavazzi has launched the HDMS Series, a single-phase motor soft-starter.

The solution is ideal for systems used in areas with weak power grids. Its design and control algorithm eliminate the need for a traditional start capacitor, effectively increasing reliability.

This same innovative control strategy allows the HDMS to start Capacitor Start / Capacitor Run (CSCR) motors, and in the case of Permanent Split Capacitor (PSC) motors, virtually eliminate the starting current.

The HDMS is a good choice for applications such as heat pumps, submersible pumps, or other scroll compressor loads connected to generators or electrical inverters. Features include Near Field Communication (NFC), Modbus communication, and ease of use as the HDMS does not require any user settings or adjustments.


Other features of the HDMS include single-phase 110 to 230 VAC, 50/60 Hz operating voltage range, a self-learning algorithm that continuously adapts to load conditions for motor start optimization, and a broad operational current range: 12, 25, 32, 37 Arms @ 60°C (140°F).
