As the use of 690 V energy efficient motors continues to grow within industrial applications, ABB has launched its new range of EQ A44 three phase 690 V high-functionality electricity meters, which deliver outstanding performance for the reliable metering of energy usage.
ABB’s EQ A44 552-110 or A44 553-110 meters can be easily installed without the need for additional voltage transformers, which reduces purchase and installation costs. Delivering cost savings of up to three times the purchase price of 690 V instrument transformers, the range is economical thanks to a lower power consumption of less than 2.2 VA.
Mats Karlberg, product manager for electricity meters, from ABB said: “We’re proud to bring the only energy meters that satisfy the requirements of 690 V applications to the market. When we invest in developing new products, we always have the end-user in mind. We focus on how we can design the most sophisticated solutions that deliver outstanding results, while cutting costs and making life easier for our customers.”
Removing the need for voltage transformers in 690 V installation, the new single device allows for faster wiring and fewer settings. Profitability is enhanced because fewer components are needed to deliver the same functions as traditional voltage transformer meters.
EQ A44 is available in a wide range of voltages, from 57.7 to 500 or 100 to 690V phase to phase and is suitable for use in a variety of temperatures. It can be used in three or four wire installations, making it easier to install new meters or retrofit older versions. Both models fit standard DIN Rail enclosures, making them compact and easy to locate and provide easy access to energy efficiency data which supports ISO 50 001 certification.
The use of a RS-485 or M-Bus interface improves communication. Other enhanced features include a range of 25 alarm functions and an easy to read pixel oriented back light display, which shows up to four data items at the same time. A sealable transparent lid also protects against unauthorized usage.
The new 690 V meters are suitable for use in a wide range of applications including the processing industry, mining, docks and harbor management, wind turbines, water and waste water management.
