AC/DC Electronic Loads

Benchtop, Modular, and High Power

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.

Benchtop DC Electronic Load

Chroma 63000
