The VECTO 3.4 is the latest version of the VECTO 3. A comprehensive list of upgrades can be found on CT Lab's website.
The VECTO 3 is a multifunction, waveform synchronised, Ed3.0 Class-A power quality analyser, recorder and measurement device, sampling at 1.5MHz with the ability to store 50kHz time synchronised waveforms.
The device is permanently GPS or PTP time synchronised to within <100ns from absolute time, and offers high accuracy and high-bandwidth analog inputs with programmable gain. It offers secure Gigabit bandwidth IP integration via Ethernet, Fiber, WiFi and 4G Cellular interfaces. The devices are powered from either AC, DC or POE-Plus sources and offers built-in battery support. VECTO devices can operate stand-alone or as part of a fleet of permanently connected devices managed by VECTO Grid OS, the big data hosting, visualisation, analysis & reporting software platform. Various value-adding software modules are available.
