Carlo Gavazzi: Dynamic Motor Starters for 1-Phase Scroll Compressors and Submersible Pumps

March 16, 2020

CARLO GAVAZZI has launched the HDMS Series, a single-phase motor soft-starter. It is an ideal solution for systems used in areas with weak power grids. Its unique design and control algorithm eliminate the need for a traditional start capacitor, effectively increasing reliability. This same innovative control strategy allows the HDMS to easily start Capacitor Start / Capacitor Run (CSCR) motors, and in the case of Permanent Split Capacitor (PSC) motors, virtually eliminate the starting current.

This product offers as much as 70% current reduction when compared to Direct On-Line (DOL) starters, which makes the HDMS the perfect choice for applications such as heat pumps, submersible pumps, or other scroll compressor loads connected to generators or electrical inverters. Innovative features include Near Field Communication (NFC), Modbus communication, and ease of use as the HDMS does not require any user settings or adjustments.

Features of the HDMS include:

- Single-phase 110 to 230 VAC, 50/60 Hz operating voltage range
- Self-learning algorithm continuously adapts to load conditions for motor start optimization
- Broad operational current range: 12, 25, 32, 37 Arms @ 60°C
- No start capacitor required
- Tool-free design for quick, error-free installation
- Data downloads via NFC communication with 143 alarm event storage capacity to expedite troubleshooting
- Real-time data analysis through Modbus communication
- Specialized algorithm for scroll compressors and submersible pumps
- SCR protected relays for increased lifetime
- 2 relay outputs (configurable logic) for Alarm, Top of Ramp
- Integrated Class 10 motor overload protection
- Conformal coated PCBs for additional protection against humidity
- Agency approvals: cULus Listing, CE certification

The HDMS Series Motor Starters are the best choice for increasing reliability, reducing costs on utility contracts and improving motor operation.

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
