N62400S
Low-voltage, high-current load
Ultra-low-voltage DC load down to -3 V for fuel cell and extreme current testing.
The N62400S series is the specialist solution for ultra-low-voltage high-current applications, supporting an extended operating range down to -3 V at maximum current. This enables highly realistic simulation of operating conditions where extremely low voltages occur under heavy load. This makes the S model ideal for fuel cell development, fuel cell stacks, low-voltage energy systems, and advanced battery testing, where conventional electronic loads cannot accurately reproduce real conditions. Operating modes such as CC, CV, CR, CP, dynamic testing, and charge/discharge functions ensure repeatable and realistic test scenarios. The compact 3U rack design and LAN, RS232, and CAN interfaces allow easy integration into automated test benches and R&D environments.

N62400 Series: Programmable DC Load for High-Current Low-Voltage Applications
In industrial testing of low-voltage components such as fuel cells, precise load simulation at decreasing voltage levels is a key technological challenge. The N62400 series was developed specifically to absorb extremely high currents at very low voltages in a stable and repeatable manner.
With currents of up to 1200 A at voltages starting from 0.2 V, the system enables complete characterization of single cells and other high-current devices under test across the entire relevant operating range. The combination of robust hardware architecture, high readback accuracy, and efficient automation makes this series a powerful solution for research, development, and industrial quality assurance.
Key Advantages and User Benefits
The N62400 series combines high power density with control technology specifically designed for low-voltage, high-current testing.
Typical Applications
The N62400 series is used wherever high currents at very low voltages must be absorbed precisely and repeatably.
Analysis of single cells and stacks that provide very low voltages but must be loaded with high currents.
Standards-compliant charge and discharge cycles as well as precise determination of the internal resistance of energy storage systems.
Testing of DC/DC converters, busbars, and high-current connectors, especially in the field of e-mobility.
Functionality and System Description
The N62400 series operates as a fully programmable DC load and offers the four classic basic operating modes for static and dynamic test tasks.
