Single-channel electronic DC loads 150W to 200kW+

Electronic DC Loads – Precise and Versatile Testing Systems

Electronic DC loads are essential testing devices used to simulate real operating conditions in the development, quality assurance, and production of power supplies, batteries, and electronic components. They enable precise measurements and testing under various load conditions by efficiently absorbing electrical energy and generating defined load profiles.

Why Do You Need an Electronic DC Load?

DC loads are used to test and analyze the performance of power sources such as power supplies, batteries, fuel cells, or DC/DC converters. They offer different operating modes, including constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR). Modern models also feature protection functions such as OCP, OVP, or OTP, short-circuit simulations, impedance tests, and many other test procedures.

Advantages of Electronic DC Loads Over Other Load Types

• Precise control and high measurement accuracy
• Simulated dynamic load behavior to replicate real operating conditions
• High flexibility with various load modes and programmable functions
• Protection functions for DUTs to prevent damage during testing
• Easy integration into test systems via digital interfaces like LAN, RS232, CAN, or GPIB
