One Lightweight Package- Includes Storage of Cables and Probes
World's First Battery Powered Current & Voltage Source
The PowerMaster® Model 335V Load Box is the first battery-powered voltage and current source for the industry-leading handheld PowerMaster® 3 Series and PowerMaster® 6 Series analyzers. By utilizing a Model 335V with a PowerMaster® 3 or 6 Series, the user will have the ability to perform phantom load meter testing up to 277 VAC and 5A while implementing the new current harmonic waveforms from the ANSI C12.1.
In addition, the PowerMaster® Model 335V Load Box will give the user the ability to perform a CT Added Burden, Direct Burden Measurement, and CT Demagnetization. The compact size of the 335V provides storage of all the standard test accessories of the lightweight PowerMaster® 3 or 6 Series analyzers.
Powermetrix continues to Raise the Standard of versatility, functionality, and portability.
