Chroma 63209 DC Electronic Load

The Chroma 63209 DC Electronic Load is a 0-80 V, 0-1000 A, 15 kW direct-current load simulation system developed to test a wide array of DC power sources, server power supplies, battery chargers, converters and other DC power-supplying instruments. The Chroma 63209 also features a Master/Slave paralleling control mode for high-power applications, and multiple loads can be operated in tandem and synchronized via a loading control signal.

Chroma 63209 models offer four operating modes for different load simulation methods. The CC and CR modes diagnose constant-voltage converters and power supplies, while CV mode mimics a battery system to test battery chargers and CP mode simulates real-discharge profiles. Throughout the four modes, dynamic loading is possible up to 20 kHz, and only 1 V draws the rated current of the device.
