Dewesoft SIRIUS XHS 4xHV and 4xLV three-phase power analysers

The Dewesoft SIRIUS XHS 4xHV and 4xLV are three-phase power analyser data acquisition (DAQ) systems.

Utilising by Dewesoft’s HybridADC signal-conditioning technology, each channel offers an ultra-high bandwidth mode — up to 5 MHz bandwidth and 15 MS/s sampling — suitable for capturing fast inverter switching and high-frequency transients — and high-dynamic alias-free mode with up to 2 MS/s sampling with 150 dB dynamic range, for greater precision in harmonic, efficiency and long-term power quality measurements.

With four high-voltage (HV) and four low-voltage (LV) isolated inputs, the system provides true three-phase plus reference channel capability — making it suitable for inverter, motor-drive, renewable energy and grid-power analysis.

In terms of connectivity and scalability, the SIRIUS XHS supports USB 3.0, Gigabit LAN with PTP time synchronisation, OPC UA, XCP, CAN and CAN FD protocols — allowing integration with real-time controllers, PLCs and distributed data systems.

Engineers can stack, daisy-chain, or distribute units via Ethernet, with data and time synchronisation handled through a single cable. The system’s modular design allows for straightforward expansion — from compact portable set-ups to large laboratory test benches.
