Precision AC Electronic Loads for Power Conversion Validation

Chroma programmable and regenerative AC electronic loads deliver state-of-the-art load emulation for R&D validation, quality assurance, and high-throughput production environments. Designed to reproduce both linear and non-linear AC load characteristics, our instruments enable test engineers to rigorously evaluate uninterruptible power supplies (UPS), grid-tied and off-grid inverters, AC sources, EV charging infrastructure (EVSE), fuses, circuit breakers, and power components.

By integrating advanced digital signal processing (DSP) and real-time waveform compensation technology, Chroma AC loads accurately simulate real-world operational stress—including high crest factor current spikes, adjustable lagging/leading power factors, and sudden inrush currents—without distortion.

Frequently Asked Questions

What is the advantage of using a regenerative AC electronic load?

Regenerative AC electronic loads recycle absorbed electrical energy back into the facility power grid with up to 89% efficiency. This substantially reduces electricity consumption, lowers HVAC thermal loads in test laboratories, and decreases operating costs during long-duration or production-line testing.

Can Chroma AC electronic loads simulate non-linear and rectified load profiles?

Yes. Chroma AC loads feature programmable crest factor control (1.414 to 5.0) and power factor adjustments (0 to 1 leading or lagging). This enables realistic emulation of rectified switching power supplies, IT server loads, and complex inductive or capacitive industrial equipment.

Are Chroma AC loads compatible with automated test environments (ATE)?

Yes. All models come equipped with digital communication interfaces such as GPIB, RS-232, USB, and Ethernet/LAN. They support standard SCPI commands as well as dedicated Chroma SoftPanel software for easy integration into automated lab platforms.
