AC DC Electronic Loads

We are Known for Making the Best Electronic Loads

Electronic loads are pivotal in testing and validating power sources such as batteries, fuel cells, and renewable energy systems. Our programmable electronic loads simulate real-world electrical loads to evaluate performance, efficiency, and reliability under different conditions. We provide the widest range of voltages, currents, operating modes, and features. Here are a few items that set us apart.

  • Highest accuracy available
  • Full current down to 0.4VDC
  • CZ mode for turn on capacitive load simulation (up to 50,000uF capacitance emulation)
  • User-defined waveforms
  • Timing measurements for battery testing
  • Real-time power supply load transient response simulation and Vpk+/- measurement
