PQube Classic

The PQube is like an aircraft's black box, it records the details of every power disturbance. When your system is "flying" normally, your PQube records every detail about power consumption for you. No software required. Lab grade precision. Plug-and-play.

Tiny. User friendly. No software required.

Power Quality monitoring: Your PQube is like the black box on an aircraft: if anything goes wrong with the power, it records all the details.
