QuantumX 4‑channel High-voltage Measurement Module

MX403B: Versatile and Dynamic High-voltage Measurements

The QuantumX MX403B is a high‑resolution, 4‑channel voltage measurement module designed for dynamic applications requiring precision and reliability with uncomplicated system integration. Built for demanding test environments, it delivers up to 100 kS/s per channel, 24‑bit resolution, and certified safety according to IEC61010 (VDE).

Key features

• 24‑bit A/D converter
• Accuracy class 0.05
• Sample rates up to 100 kS/s per channel
• Configurable digital filters (Bessel, Butterworth)
• Electrically isolated differential inputs for all four channels
• Certified to stringent IEC standards by VDE for high‑voltage scenarios (up to 1000 V CAT II, 600 V CAT III)
• Safe 4‑mm lab sockets ensure secure connection in high‑energy environments
• Three freely selectable measuring ranges: ±10 V, ±100 V, ±1000 V
• Seamless integration with the QuantumX family
• Distributed, synchronous operation over long distances via digital data transfer (Ethernet with PTP and FireWire)
• Full software integration for real‑time analysis and system scalability

Maximum detail and accuracy with safety you can trust

The MX403B acquires voltages up to 1,000 V with high fidelity using a 24‑bit ADC and high sampling rates to provide deep insight into fast electrical events. Each of its four channels is fully isolated and individually configurable, enabling safe measurement of high‑voltage systems without interference. Digital filters, real‑time data transfer, and stored factory calibration ensure precise, trustworthy results for all dynamic measurement tasks.

Typical applications

The MX403B is optimized for use in fast, dynamic environments where high electrical accuracy and maximum safety are essential, such as:

• Testing electric actuators (pumps, drives, generators) in mobile or stationary setups
• Analyzing energy storage systems and power electronics in automotive and aerospace development
• Laboratory and test bench measurement tasks requiring synchronized electrical and mechanical data acquisition
• Creating complex energy balances when combined with torque transducers

Easy system integration when measuring multiple quantities

MX403B integrates seamlessly withing the QuantumX family, enabling all electrical, mechanical, and thermal measurement quantities as well as CAN bus signals to be synchronously acquired and analyzed. The measured data can be integrated in parallel and in real time.

When you add in catman^® software for data recording and data analysis, you achieve a true plug‑and‑measure setup where torque, force, pressure data can be immediately visualized, stored or digitally forwarded.
