Latest QuantumX module provides synchronous measurement of high electrical voltages

HBM has expanded its QuantumX modular data acquisition platform with the MX403B module to provide high-precision measurement of up to 1,000 Volts.

The MX403B module has four differential channels for the direct measurement of electric voltages and is fitted with high insulation for maximum security. Each channel is equipped with analog anti-aliasing filters, digital filters and 24-Bit A/D converters while it outputs data with sampling rates of up to 100 kS/sec/channel and acquires signal bandwidths of up to 38 kHz.

The parameters of the measuring ranges can be freely varied or fixed at 10V, 100V and 1,000V enabling the acquisition of high voltages and smaller differential voltages from high potentials against ground reference. The module was developed to the latest IEC 61010:2013 standard and has been certified by the VDE.

The MX403B seamlessly integrates with other modules in the QuantumX family to give time-synchronous acquisition of mechanical, electrical and thermal measurands and digital bus signals. Different QuantumX modules can be integrated utilising real time via outputs such as standardized voltage, EtherCAT or CAN and can be spatially distributed.

The MX403B provides users with a flexible solution whose main applications are for mobile and stationary tests of energy storage systems or complex mechatronic systems.


Founded in Germany in 1950, HBM is today the technology and market leader in the field of test and measurement. HBM’s product range comprises solutions for the entire measurement chain, from virtual to physical testing. The company has production facilities in Germany, USA and China and is represented in over 80 countries worldwide.
