EL01 Electronic Load
The EL01 is a versatile, programmable electronic load with a power range of 350– W—designed for anyone in a laboratory, development, or test environment who demands the highest standards of accuracy and reliability. With its wide voltage and current range, sensitive control, and high resolution, the EL01 is ideal for demanding tests of power supplies, batteries, and other energy sources. It combines precise measurement technology with ease of use and robust engineering.
The device offers exceptional flexibility in terms of control: it can be operated directly on the unit via the keypad and rotary knob, or externally via USB, SCPI, or user-friendly PC software. Extensive features, such as 40 storable test configurations, simplify the repetition of complex test sequences and make the EL01 an attractive option for automated testing and production testing as well. Whether for simple load simulation or dynamic current profiles—the EL01 can be optimally adapted to individual requirements.
Reliable protection features such as overvoltage, overcurrent, and overload protection ensure maximum safety during daily operation. This keeps the device protected at all times, even under extreme conditions. A special feature is the high-resolution precision mode, which enables accurate readings with minimal ripple and very low noise in the low voltage and current range—ideal for sensitive applications where every detail matters.
With its combination of performance, precision, and ease of use, the EL01 is the perfect solution for professional testing tasks. It supports a wide range of operating modes, operates reliably, and delivers reproducible measurement results you can count on. This makes it not only a practical tool for daily measurement tasks, but also an investment in quality, efficiency, and safety in your testing environment.
