Carlo Gavazzi

 

Carlo Gavazzi has enhanced its DPB and DPC Series of three phase monitoring relays with an upgraded switch mode power supply, which provides a wider input voltage range to cover different mains voltages, while reducing heat dissipation and improving reliability and stability. The DPB series has an input voltage range of 208 VAC to 480 VAC, while the DPC series has an input voltage range of 208 VAC to 690 VAC. Most of the new models feature an expansive frequency range of 50 Hz to 400 Hz, making them ideal for a wide range of applications.

Three phase monitoring relays are ideal for protecting motors from severe damage that can result from loss of a phase, phase imbalance, or phase reversal. Motors can be found in a wide range of applications including: aviation, food & beverage, HVAC systems, machine tool, marine, material handling and water treatment.

 

  • DIN rail and Plug in (PPB) types
  • Noise, harmonics, and transient filtering
  • Significant reduction in power consumption versus previous models
  • Wide input voltage and frequency range
  • Voltage ranges selectable by DIP switches
  • Options for detecting phase sequence, loss, asymmetry, frequency, and tolerance

Condition monitoring of critical components on machines delivers enormous benefits to productivity in a plant.  Rather than have a motor, pump, or compressor unexpectedly fail and the machine be inoperable until a replacement part is installed, condition monitoring of those critical pieces on the machine can provide warning signs that something is about to go terribly wrong. Vibration measurements on rotating equipment can detect when there is imbalance or degrade on rolling bearing elements.

Unplanned downtime threatens productivity and profit across industrial and commercial sectors. In a recent survey of these customers, 20% rate reaching zero unplanned downtime as their top priority, and 70% consider it a “very high priority.”

 Often, downtime comes as a surprise because facility operators lack visibility into their operations. Hardware failures and malfunctions account for 45% of downtime incidents – but 71% of field service decision makers aren’t fully aware of their assets’ maintenance schedule.

Those of you in the food industry are already familiar with the Food Safety Modernization Act (FSMA)—a law that focuses on preventing contamination, rather than reacting to the problem after the fact. A big part of FSMA compliance has to do with the design of plant equipment, which includes the electrical components that provide power to manufacturing lines.

Fortunately, MENNEKES offers a variety of electrical products that make FSMA compliance easier than ever. Let’s explore this topic in our new blog post.
