The Chroma 63815R-350-105 Regenerative AC Electronic Load is a high-performance programmable load designed for AC power source testing with energy recovery. Offering 15kVA of regenerative loading capacity, this unit is well-suited for validating grid-tied inverters, energy storage systems, AC EV chargers, UPS devices, and power distribution components in smart grid and renewable energy applications.
Operating across a wide input range of 50–350 Vrms (L-N), the 63815R-350-105 supports both single-phase and 3-phase systems with frequency flexibility from 30 to 100 Hz. Users can simulate a wide variety of real-world load conditions, including pure resistive, reactive (inductive or capacitive), constant power, and rectified (diode bridge-like) loads. This functionality makes the 63815R not just a passive sink, but an intelligent load emulator.
The regenerative feature allows the unit to return consumed energy back to the grid, reducing heat and energy waste—ideal for continuous testing or production environments. The model includes precision measurement capabilities and protection systems for fault-tolerant, safe operation in critical testing scenarios.
Whether referred to as Chroma 63815R, 63815R-350-105 AC Load, Chroma 63815R 15kVA, or Chroma regenerative AC load, this model meets the demands of engineers developing next-gen power electronics in EV, solar, and energy storage sectors.
