The PowerLogic PM8343 is a DIN rail power analyser for low and medium voltage applications and AC/DC control voltage. It was developed to ensure the availability and efficiency of your energy-critical systems. It creates energy transparency and provides actionable data on complex power quality conditions. With the modular, flexible and powerful ION technology, customised applications can be created for each measuring device. It features high accuracy, multiple communication ports, a web-based user interface and a graphical colour display. This power analyser also features integrated power quality analysis and patented fault direction detection. Certified by independent laboratories for class 0.2S accuracy at active energy (IEC62052-11, IEC62053-24, IEC62053-22). Also certified for power quality (IEC62586-2, IEC61000-4-30 Class A). Cybersecurity features include secure protocols (HTTPs, sFTP, Secure ION), security event logging, syslog protocol. Ability to enable/disable communication ports and support for 50 configurable user accounts to manage access. With 512 MB memory for up to 64 data logs (1024 channels), more than 50 user-definable alarms, waveform logging with up to 512 samples/cycle, 1/2 cycle RMS logging. Memory can also be used for custom web pages, min/max logs, energy trends and operating hours. Time stamp for events with an accuracy of +/-1ms using time synchronisation. Time synchronisation methods that include PTP (IEEE1588), NTP, IRIG-B, GPS ASCII (RS485) and network time setting function. 3 digital inputs and one digital output, plus the ability to add up to 4 option modules. The input/output option modules include 2 relays and 6 digital inputs or 2 analogue outputs and 4 analogue inputs. Wide control voltage range from 90-415 VAC / 110-415 VDC. Operating environment from -25 to +70°C, humidity from 5% to 95% and operating altitude up to 3000 m.
