  • Compliant with EN50160 Standard
  • Class A power analyzer certificated according to 61000-4-30 standard
  • 0.2s energy accuracy class according to IEC 62053-22 standard
  • TFT 640×480 resolution colored display
  • 25.6 kHz high sampling frequency
  • Programmable record feature in many functions with 1 GB internal memory
PEM735 Power Quality Recorder is a complete grid analyzing device designed according to EN50160 standard. Device makes accurate and detailed grid analyzing with four current measurement inputs for three phase and neutral, and also with four voltage measurement inputs. Power Quality Recorder has Class A certificate according to 61000-4-30 standard, measures and records harmonic parameters up to 63, voltage and current unbalance, voltage sag/swell, transient monitoring, flicker according to EN50160 standard. PEM735 Power Quality Recorder provides long term records as table and graphical in its internal 1 Gb memory. Device can record 1024 events and has a 25.6 kHz high sampling frequency. Communication can be made over Modbus-RTU and Modbus-TCP/IP. It is possible to monitor the PEM735 Power Quality Recorder with any internet browser for real time values, graphic displays, reporting according to EN50160 without need of PC or application. Also setup menu can be done over the browser too. There are 8 digital inputs and 6 programmable outputs on the device whose sampling speed is 1 kHz. RS485 communication has galvanic isolation port in order to protect from external factors. PEM735 Power Quality Recorder dimensions are 144x144 mm which is commonly used. PEM735 allows you to receive real time and previous measures of the system and reports without any extra program need.
