All devices are equipped with our HybridADC signal conditioning technology capable of 15 MS/s sampling rate, 5 MHz bandwidth (Voltage), and >500 kHz bandwidth (Current). The device chassis is IP67 protected and can work at -20 °C to +70 °C.

Safety and isolation

Safety first! SIRIUS® XHS-PWR data acquisition hardware and signal cables are designed and tested according to the EN 61010-1 safety standard, including high voltage interlock and temperature monitoring.

The instruments also provide a high channel-to-channel and channel-to-ground isolation (CATII 1000 V) which prevents damage to the systems from excessive voltage and avoids ground loops.

SIRIUS® XHS-PWR instruments are very rugged and comply with IP67 environmental protection. They are also crafted for a wide operating temperature range of -20 °C to 70 °C.

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.

We have two options:

• DS-18xLAN: Our most capable Ethernet switch is an 18-port network switch that supports high-speed connectivity up to 10 Gbps. It features a PTP synchronization mechanism and offers a passive PoE option for powering external Ethernet devices. It comes in three variations with rugged LEMO and RJ45 connectors.

• DS-6xLAN: This one is a 6-port gigabit network switch with 4 downlink ports on the front panel and 2 uplink ports on the back panel.

Applications

SIRIUS® XHS-PWR data acquisition systems are designed for testing electric vehicles and their components. Some of the main applications include:
