The DEWE3‑PA8 is a high-end, mixed-signal power analyzer mainframe equipped for multi-phase and precision power measurement. It features 8 TRION(3) module slots for up to 16 power phases, delivering synchronized, high-speed acquisition with extremely low measurement error..
This all-in-one chassis is optimized for dynamic and polyphase power analysis—covering 4-phase as standard, and extending up to 16 phases. It supports continuous mixed-signal data capture, combining synchronized power and auxiliary inputs seamlessly. The 18-bit, 10 MS/s modules with modular sub-channel design ensure both precision and flexibility. Gap-free waveform logging at ~1 GB/s enables analysis of transient events, harmonics, and efficiency metrics. The system also integrates a redundant transducer power supply, simplifying setup by eliminating external power units.
Equipped with comprehensive synchronization options (TRION-SYNC, GPS/PTP/IRIG), it supports distributed setups and front-end deployment. Additionally, its software (OXYGEN) enables cycle-accurate power calculations, flexible multi-phase grouping, and seamless test-stand automation via standard industrial protocols and real-time interfaces.
