highlights
HybridADC signal conditioning technology
HybridADC delivers the best of both worlds, combining high bandwidth and dynamic acquisition capabilities. It features 16-bit ADCs with up to 5 MHz bandwidth and a sampling rate of up to 15 MS/s for high-speed data collection. Additionally, it offers high-dynamic, alias-free acquisition with a sampling rate of up to 2 MS/s. Modes are software selectable for every input channel.
15 MS/s @ 5 MHz bandwidth
SIRIUS® XHS instruments offers up to 15 MS/s sampling rate with 5 MHz bandwidth. It captures transients down to microseconds levels. The sampling rate is software selectable for every analog input channel.
High-voltage measurement
SIRIUS XHS-PWR can directly measure ±2000 V on its single-channel high-voltage input with 0.03 % accuracy of the reading.
DC-CT current technology
SIRIUS® XHS-PWR instruments have an embedded DC-CT current transducer with high current measurement accuracy. DC-CT is a patented current measurement technology.
Modern data interfaces
SIRIUS® XHS-PWR supports gigabit LAN data interface (Ethernet), CAN bus, XCP, and OPC UA outputs.
Open protocol support
Data is transferred to any host using the open OPC UA industry-standard protocol. In parallel the data is available over XCP or CAN protocols, allowing connection to ECU calibration software packages like ETAS INCA or Vector Canape.
PTP synchronisation
Even though users can select some channels to be high bandwidth and some to be alias-free, filtering is designed in such a way that all signals are perfectly time aligned with zero phase shift. Multiple devices can be synced together using the PTP synchronization method.
High galvanic isolation
High channel-to-channel and channel-to-ground isolation up to CATII 1000V. This prevents damage to the systems from excessive voltage and avoids ground loops.
Rugged and safe
SIRIUS XHS-PWR is IP67-rated for operation in harsh environments and crafted for a wide operating temperature range (from -20°C to 70 °C). The device is designed and tested according to the EN 61010-1 safety standard.

SIRIUS® XHS-PWR overview
Vehicle electrification is the major trend for driving innovation in the automotive field. This requires the implementation of intelligent management and smart distribution of in-vehicle electric power. The development of efficient and EMC emission-less electric components like electric motors, inverters, and charging stations, at the power management and semiconductor level is in full swing. Precise voltage and current measurements are required for the prediction of vehicle energy consumption for both development and vehicle operation.
SIRIUS® XHS-PWR is a family of data acquisition devices designed for direct measurement of high voltage, current, and electrical power. It is primarily designed for testing all sorts of electric vehicles such as electric passenger cars, trucks, busses, and heavy machinery.
You can run your power lines straight through the SIRIUS® XHS-PWR instrument. On the inside, it features an integrated patented DC-CT® current transducer for very precise current measurements.
The Dewesoft SIRIUS® XHS-PWR delivers state-of-the-art integrated current and voltage sensing solutions to address the automotive test and measurements market. It offers seamless integration with the DewesoftX software, XCP or OPC/UA output on PoE Gigabit Ethernet with PTPv2 Time Synchronization. The device is a high-end data acquisition system with a 15 MS/s sampling rate @ 16 bits.
HybridADC signal conditioning technology
The SIRIUS® XHS-PWR implements our new state-of-the-art Hybrid ADC signal conditioning technology. It is capable of doing both high bandwidth transient recording and very high dynamic alias-free data acquisition. Both modes are software selectable per every channel and are able to run simultaneously.
HybridADC mode of operations
High bandwidth mode: This mode offers an extremely high bandwidth of 5 MHz and a 15 MS/s sampling rate. SIRIUS® XHS-PWR devices can perfectly acquire impulse, step, and square signals without any ringing or overshooting. Such a mode is perfect for transient recording and applications such as power analysis. Such acquisition mode is typically found in SAR ADCs.
High dynamic alias-free mode: This mode is used with sampling rates up to 1 MS/s. The data is acquired with a dynamic range of up to 150 dB. The alias-free filter with a bandwidth close to the Nyquist criteria is used for frequency domain analysis of signals like sound and vibration (NVH). This behavior is very similar to Sigma-Delta ADCs.
DC-CT® current measurement technology
SIRIUS® XHS-PWR is the first product that provides a 1000 A calibrated range with 2000 A peak current sensing up to 2000 V state-of-the-art isolated current sensing technology with a core diameter of 5 cm only.
DC-CT® represents an innovative principle of isolated measurement of AC and DC currents. This compact-sized patented current measurement technology allows you to measure peak currents and leakage currents up to 2000 A. And it can do it with high bandwidth and ultimate performance.
DC-CT® is energy-efficient, compact in size, low noise, and cost-effective current measurement technology. Existing products range from 2 A and up to 2000 A, up to 1 MHz bandwidth, with target accuracy from 0.1% down to 0.01%:
| Sensor type | Current | Isolated | Range | Bandwidth | Linearity | Accuracy | Temp. drift | Consumtion |
|---|---|---|---|---|---|---|---|---|
| DC-CT | DC/AC | Yes | High | High | Excellent | Very High | Very Low | Medium |
| Fluxgate | DC/AC | Yes | High | High | Excellent | Excellent | Low | High |
| Hall | DC/AC | Yes | High | Medium | Medium | Medium | High | Low-Med |

Interface and connectivity
A single Ethernet cable is required for data transfer, power, and synchronization. This simplifies the setup and configuration for in-vehicle testing applications. For testing multiple in-vehicle components more devices can be connected via a dedicated 6-port network switch (DS-6xLAN-L1B) which provides PTPv2 synchronization for synchronizing the devices.
SIRIUS® XHS-PWR instruments offer many data interface options for reliable integration into other systems. The data can be transferred to any host using the OPC UA industry-standard data protocol. In parallel the data can also be available over XCP and CAN protocols, allowing connection to ECU calibration software packages.
Connect and synchronize multiple units with DS-6xLAN switch
Multiple SIRIUS® XHS-PWR can easily be connected using our industrial DS-LAN ethernet switches. Our ethernet switches can provide power, synchronization, and data to multiple connected devices.

Hybrid ADC is the new AD converter technology developed by Dewesoft. The technology allows the user to select two modes of operation for each input channel:
- High-bandwidth mode: offers 5 MHz bandwidth and 15 Ms/s sampling rate. This mode can perfectly acquire impulse, step, and square signals without any ringing or overshoot. This mode is perfect for transient recording and power analysis. Such acquisition mode is typically found in SAR ADCs.
- Alias free mode: up to 1 Ms/s data can be acquired with extremely high dynamic range, similar to our dual 24-bit SIRIUS DualCoreADC devices. The data is totally alias-free. All higher frequencies are fully rejected. Such a mode is perfect for sound, vibration, and general data recording applications. Such acquisition mode is typically found in Sigma-Delta ADCs.
The SIRIUS XHS offers high bandwidth acquisition (5 Mhz) up to 15 MS/s per each channel or if you want to use a high dynamic alias-free acquisition than the sampling rate is limited to 1 MS/sec.
