EPSD™ (In Development)
Energy Analyzer
The EPSD™ is a 2nd generation design of the popular EnergyPro EP600i energy analyzer. It is a portable and easy to use instrument, perfect for single phase or three phase energy consumption analysis and basic power quality monitoring.
The EPSD™ supports standard wiring configurations and comes with a set of 1A – 2500A WideRangeFlexCT™. The graphics display makes setup very easy and intuitive – you can setup and record data without looking at the manual!
Feel free to contact CANDURA instruments for more information on pricing and EPSD™ applications.
