AC power analyzers measure active and reactive variables

Steinhausen, Switzerland — Carlo Gavazzi is expanding its range of compact power analysers that measure all the active and reactive variables in a wide variety of industrial applications where space is limited. The new devices provide dual pulse output for energy pulse retransmission. The WM14 range comprises two basic models for either panel or DIN-rail mounting, covering voltages from 100 to 660 V AC, making them suitable for most kinds of industrial applications. The panel mount version sits only 46 mm behind the panel so can be mounted in the entire switch and control gearing. The new additions offer an optional pulse output for measuring pure kilowatt usage or an RS485 port to give users the option to only display data measured or to both display and transmit data for remote monitoring by means of a PC, PLC or SCADA. Additional features include thermal current measurement with peak storage to allow users to check if the over current protections are adequately preset as well as IP65 rating for the WM14-96 and IP40 for the DIN mount version against water ingress and an integrated hour counter to assist maintenance planning.
