DEWE3-PA8-RM

The DEWE3‑PA8‑RM is a high-precision, rack-mounted power analyzer designed for multi-phase power measurements in automated test benches and lab environments. With 8 TRION(3) module slots, it supports up to 16 power phases and integrates high-speed sampling, real-time automation, and synchronized mixed-signal inputs..

  • Specification

The DEWE3‑PA8‑RM is tailored for permanent integration into 19″ test racks where high channel count, precision, and modularity are critical. It supports up to 16 power phases using 8 user-configurable TRION(3) power modules. The system captures data at up to 10 MS/s per channel and logs waveforms gap-free at up to 1 GB/s—ideal for high-speed transient analysis and dynamic power quality evaluations.

In addition to power signals, the system supports synchronized acquisition of mechanical, electrical, and digital inputs, making it a complete mixed-signal measurement platform. This is crucial for applications such as inverter efficiency testing, e-mobility R&D, and powertrain validation.

For automation, the DEWE3‑PA8‑RM offers real-time data output with sub-4 ms latency and supports industrial protocols like SCPI and XCP. An optional front-end firmware mode enables control from remote hosts without running Windows locally.

Maintenance is simplified through front-facing access to module slots, fans, and filters. Transducer supply is integrated, powering up to 8 current sensors directly from the chassis.

  • Multi-Phase Support: Measures up to 16 independent power phases using modular TRION(3) power modules.

  • Rack-Optimized Form Factor: Designed for 19″ racks in a compact 5U chassis with front-facing slots and easy maintenance.

  • High Precision: Maintains ±0.03–0.04% basic power accuracy across the 0.5 Hz to 1 kHz frequency range.

  • High-Speed Sampling & Recording: Supports sampling rates up to 10 MS/s per channel with gap-free data logging at up to 1 GB/s.

  • Integrated Transducer Supply: Built-in redundant power outputs for up to 8 current transducers eliminate external supply needs.

  • Mixed-Signal Acquisition: Captures synchronized auxiliary signals such as torque, speed, vibration, CAN, counters, digital I/O, and video.

  • Real-Time Output & Automation: Provides low-latency real-time data via Ethernet UDP or EtherCAT with SCPI and XCP support.

  • Front-End Mode Support: Optional Linux-based front-end operation allows control and data streaming over Ethernet networks.
