The Measurable difference.

Power Analyzer

Modular precision Mixed Signal Power Analyzer

 

DEWETRON’s Power Analyzers offer up to 16 power channels which can be optionally expanded. The number of power groups are user definable and the wiring of power groups fits all applications: 1-phase, 2-phase, 3-phase, 6-phase, polyphase up to 9 phases. Our Power Analyzers have 0.1% basic accuracy.

Power Analyzer
DEWE3-PA8

The new Power Analyzers, DEWE3-PA8 are perfectly pre-configured measurement systems for polyphase measurements up to 16 power channels.

High performance power analysis and continuous waveform recording of any signal are standard features.
