November 28, 2017 by Manufacturing AUTOMATION
Nov. 28, 2017 – Carlo Gavazzi has added the DPA52 and DPB52 three-phase monitoring relays to its product offering, helping to protect against phase loss and improper phase sequence.
According to the company, DPB52 provides additional protection against under-voltage and over-voltage. With a built-in switch mode power supply, DPA52 and DPB52 have the added advantage of filtering and minimizing harmonic distortions, which can help prevent devices from overheating and most of all prevent failures and false alarms which could lead to unexpected machine downtime, adds Carlo Gavazzi. Both models offer a wide input voltage range, multi-colour LED indicators for diagnostic feedback, and a relay contact output. They conform to global standards such as UL 508, CSA C22.2 and EN 60947-5-1, and can be used globally in applications/markets where it is necessary to monitor phase presence, sequence, and value, such as material handling, water treatment, and HVAC.
