Chroma 63815R-350-105 Regenerative AC Electronic Load

Overview

The Chroma 63815R-350-105 is a versatile regenerative AC electronic load designed for testing renewable energy systems, energy storage solutions, hybrid PV inverters, AC EV charging stations, and bidirectional on-board chargers. With a 15kVA power rating in a compact 3U chassis, this unit eliminates waste heat generation and reduces operational electricity costs compared to traditional dissipative loads.

The regenerative feature allows the 63815R-350-105 to feed energy back into the power grid with 89% efficiency, making it particularly well-suited for UPS testing and renewable energy applications. Multiple units can be paralleled to increase load capacity for higher-power testing requirements.
