New Models of the SIRIUS® XHS-PWR Power Analyzers

Introducing the two new devices in the SIRIUS® XHS-PWR product family. SIRIUS® XHS-PWR is a distinctive 2-channel Power Analyzer specifically designed for in-vehicle testing of electric and hybrid vehicles.

We are excited to announce the addition of two new products to this family:

  1. SIRIUSi-XHS-PWR-1xHV-1xDC-CT-250A-UNI power analyzer

  2. SIRIUSi-XHS-PWR-1xHV-1xDC-CT-1000A-CON power analyzer

Both products facilitate safe, high-power, in-vehicle measurements of current, voltage, and power, tailored for e-mobility applications.

Innovative measurement technology

The current measurement employs a patented DC-CT zero-flux transducer, based on the Platiše Flux Sensor (PFS). This technology ensures high-precision measurements of both AC and DC currents (with less than 0.1% error) and offers a high bandwidth (exceeding 500 kHz). The DC-CT current transducer also features exceptionally low-temperature drift, outstanding linearity, and robust overload capability. It can easily handle measurements of battery DC and motor AC currents, including signals at higher frequencies.

Hybrid ADC technology

Our HybridADC® technology provides both high bandwidth and dynamic measurements in a single device. In high-bandwidth mode, current and voltage are sampled at rates up to 15 MS/s, with a bandwidth reaching 5 MHz.

Safety and durability

The system complies with the EN 61010-1 safety standard, ensuring channel-to-channel and channel-to-ground isolation up to CATII 1000 V. Its IP65-rated chassis, which encloses the power lines, operates reliably between -20°C and 70°C and withstands high shock and vibration levels. The device also includes internal temperature monitoring.

Data integration and synchronization

Measured values are transferable via Ethernet, XCP, OPC UA, and CAN. Data synchronization with other sources, such as CAN BUS, GPS, IMU data, video, and more, is streamlined using the IEEE 1588v2 PTP timing protocol.
