The Chroma 63211 DC Electronic Load 1000 Volts, 150 Amps, 15.6 kW is designed to test DC power sources, power electronic devices, automative battery and components testing. The high power ratings, parallel and synchronization capabilities make them the ideal tool for testing high power UUT such as SMR, UPS, batteries, and fuel cells. The 63211 can draw its rated current under very low voltage (1V typical) even under the highest specified slew rate. This unique feature guarantees the best loading performance to a low voltage power supply. With the unique external waveform simulation and Master / Slave control capability, the 63211 allows users to parallel and synchronize more than one load together using an internal or external loading control signal. This feature provides unlimited load simulation and the possibility of power expansion.
