Engineered for the tasks you face, wherever you work

Capture transient power changes with high precision:

Evaluate motor and inverter efficiency with 1 ms data updates and 600 kHz bandwidth. Even transient power losses are measured accurately.

• Capture motor power fluctuations with millisecond precision
• Evaluate efficiency for high-frequency inverters
• Automatically detect charge and regeneration to calculate efficiency

Reduce setup time in drive range testing

Ensure accurate measurements even at -7°C. With direct CAN voltage input and flexible, vehicle-side installation, test setup is faster and safer.

• Accuracy maintained at -7°C. Install directly in cold chambers
• Use a compact setup near the vehicle and expand channels with synced units
• Acquire battery voltage via CAN, safe and simple

Use it on the road Designed for real-world driving tests

Measure power without vehicle modification. OBD-II input and 10.5 V to 28 V DC power supply make in-vehicle use easy.

• Operates from −20°C to +50°C, ready for harsh environments
• Run on DC power for easy in-vehicle installation
• Use OBD-II CAN bus for safe, real-time vehicle data acquisition

Ensure production quality with waveforms and numbers

Combining waveforms and numerical values ensures reliable, quantifiable quality in mass production.

• Verify efficiency with ±0.04% accuracy at DC and 50 Hz/60 Hz
• Direct voltage input up to 1500 V DC
• 2.5 MHz sampling enables waveform evaluation of switching events

Half the Size, Maximum Precision

• The slim design clamp current sensor ensures easy installation even in tight spaces.
• Complex tasks in the engine room become simple and efficient, dramatically reducing preparation time for fuel efficiency and performance testing. Not only does it reduce setup time, but it also minimizes the risk of sensor damage from forced clamping between narrow spaces.
• Fully compliant with the WLTP and SAE J1634 standards, it provides precise AC/DC current measurements up to 200 A with an impressive DC accuracy of 0.07%.
