Fluke 1745 Three-Phase Power Quality Logger Details

Fluke's 1745 is the highest specification power logger in Fluke's 1740 series. It improves upon the functionality of the series' other models - the 1743 and 1744 - and includes an LCD screen which shows real time results and longer UPS ride-through time up to 5 hours (the 1744 only has UPS time to 3s).

Extremely easy to use and suitable for insertion into existing power quality systems, the Fluke 1745's compact design and fully insulated housing even makes it suitable for installation actually inside a cabinet or other spaces next to live power. Setting it up is as simple as possible - just configure what you want to test using the included software, connect up the included probes (the 1745 automatically recognises what type of probe is connected) and start logging within minutes!

When you're done logging, disconnect the 1745 from the system and connect it up to your PC to download all of your findings and interact with them further using Fluke's included software package.

Since it's fully configurable, the 1745 gives users access to whatever values they need. This power analyser can test V, A, W, VA, VAR, PF, energy, flicker, voltage events, THD, voltage and current harmonics, interharmonics, mains signalling, unbalance and frequency.

Fluke 1745 Three-Phase Power Quality Logger Key Features

  • Built-in LCD screen allows tracking of results in real time
  • Longer UPS ride-through time than the Fluke 1744 (5 hours on this analyser)
