AC/DC Electronic Loads: Benchtop, Modular, and High Power

Chroma is the global leader in Electronic Load manufacturing for product design validation and functional testing. Chroma programmable DC Loads are used for power conversion testing in all markets including automated test systems, LED drivers, power supply testing, battery testing, and fuel cell testing. Chroma AC Loads are designed for testing uninterruptible power supplies (UPS), off-grid inverters, AC sources, and other power devices such as switches, circuit breakers, fuses and connectors. Chroma Loads can do it all including full current down to 0.4VDC, CZ mode, user defined waveforms, timing measurements, and 3 current ranges per load. Chroma Loads come standard with either USB or RS232 ports for control and can be configured for GPIB (IEEE-488) control as well.

We know you have a choice when selecting an electronic load, but the advantage is clear with Chroma. We invest more in R&D than any other manufacturer, so you can be sure you are getting the most out of your lab’s equipment budget.

Advantages include:

  • 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
