The revolutionary G4500 BLACKBOX is the next generation in PQ Analysers that provides accurate detection & isolation of PQ problems for effective preventive maintenance. With its’ patented data compression algorithm, the PQZIP, the BLACKBOX stores onboard all the waveforms of every network cycle up to a 1+ year, at a resolution of 1,024 samples per cycle.

The G4500 Portable BLACKBOX continually records & measures over 10,000 electrical parameters automatically, all the time for more than a year. Capture everything & get down to the root cause of all Power Quality issues - Trends, Volts/Amps/Hz, Events, Harmonics, THD, Flicker, Power & Energy.

The wireless G4500 BLACKBOX is equipped with a built-in 802.11 b/g access point and Ethernet router, allowing it for portable analysis from any remote location.


Quick, Easy, Mobile Deployment.
Install Devices on a Temporary Basis as Needed.
Produced Detailed Statistical Records.
Troubleshoot PQ Data at High Resolution.
No. of Inputs: AC - 4 (3 phases & neutral), DC - 1.
