Carlo Gavazzi HDMS Single-Phase Dynamic Motor Starter

Carlo Gavazzi's HDMS is a dynamic motor starter for single phase scroll compressors and submersible pumps. Through an innovative control strategy, Capacitor StartCapacitor Run (CSCR), motors, can now be started without a start capacitor. In case of Permanent Split Capacitor (PSC) motors, the starting current is virtually eliminated.

All the HDMS PCBs have conformal coating for higher resistance to harsh environmental conditions. 

The ramp-up time is limited to a maximum of 1 second making it an ideal solution for scroll compressors and submersible pumps.

FEATURES

• No start capacitor required (load conditions apply). More reliability for your systems especially in weak grids.
• Cost savings. HDMS achieves an exceptional current reduction with respect to traditional soft starters. Lower starting current helps you save on utility contracts.
• Less over-rating for generator driven loads. The starting current is limited to < 1.8 HDMS nominal current. This lower start current reduces the starting VA required. In case of generators, lower power generators can be used.
• No settings required. Optimal starts in every condition without the need for user adjustments.
• Adapts to load conditions. The self-learning algorithm automatically adjusts the internal start parameters in case of unbalanced pressures.
• Faster installation. Tool-free terminals ensure a much faster and easier installation.
• Motor overload protection (Class 10). Built-in thermal model for Class 10 overload protection.
• Integrated protection. Diagnostic functions provide additional protection against abnormal operating conditions.
• Complete monitoring. The HDMS is equipped with a Modbus/RTU communication port by 2-wire RS485 connection for real time monitoring of critical parameters.
• NFC history file download. Through the NFC communication, users can download data of the very first 8 starts and the last 24 starts performed by HDMS. Download can be done via (Android based) smartphones and tablets or PC.
• Faster troubleshooting. HDMS stores the last 143 alarm events information to facilitate troubleshooting.
