  • Specification

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.

  • Multi-Phase Power Analysis: Measures up to 16 independent power phases with synchronized voltage and current inputs.

  • High-Speed Sampling: Up to 10 MS/s per channel with 18-bit resolution for capturing fast transients.

  • Precision Accuracy: Delivers stable measurement accuracy of ±0.03–0.04% from 0.5 Hz to 1 kHz.

  • Gap-Free Data Logging: Continuous waveform recording at up to 1 GB/s without data loss.

  • Modular TRION(3) Architecture: Eight user-swappable power module slots with built-in voltage and current sub-modules.

  • Integrated Transducer Supply: Built-in redundant power supply for up to 8 current transducers (±15 V/±9 V).

  • Mixed-Signal Compatibility: Captures auxiliary data such as torque, speed, vibration, CAN, and video alongside power data.

  • Automation & Real-Time Output: Supports SCPI/XCP automation and real-time data interfaces like UDP and EtherCAT with latency as low as 2–4 ms.

  • Flexible Synchronization: Supports GPS, PTP, IRIG, PPS, and TRION-SYNC for distributed setups.

  • Certified Accuracy: Delivered with ISO 17025 compliant calibration certificate.
