N61100 Series Multi-Channel DC Electronic Load: High-Precision Test Solutions for Industrial R&D and QA Environments
In modern automated test environments, the balance between channel density, precision, and processing speed is a decisive competitive factor. The N61100 series was developed as a highly integrated, programmable DC electronic load in a compact 19-inch 3U format to meet these requirements efficiently.
With a communication response time of ≤ 5 ms, high system stability, and up to 12 channels per unit, the series replaces multiple standalone devices within a single platform. This significantly reduces investment costs, rack space requirements, and integration effort in test systems.
Key Benefits for the User
The architecture of the N61100 series provides targeted features for optimizing industrial test cycles in research, development, and quality assurance.
Maximum Integration Density
Up to 12 independent channels in just 3U enable significant rack space optimization in high-density test environments.
Dual Measurement Ranges
Separate measurement ranges for voltage, current, resistance, and power improve accuracy across wide load ranges.
Integrated LED Simulation
A software-configurable LED simulation replaces traditional load banks with precise models based on Rd and Vf.
High-Speed Sampling
With a sampling rate of up to 500 kHz, waveforms and ripple effects can be analyzed directly within the device in great detail.
Precise Remote Sensing
2-wire and 4-wire sensing compensate for voltage drops across the load cables and ensure accurate values directly at the DUT.
Comprehensive Protection Functions
OVP, OCP, OPP, OTP, and RV ensure maximum operational safety for both the system and the device under test.
Typical Application Areas
Thanks to its high flexibility and specialized operating modes, the N61100 series is suitable for a wide range of industrial test scenarios.
