Chroma 63472 High Current DC Load

The Chroma 63472 is a high slew rate DC electronic load designed for testing voltage regulator modules (VRMs), embedded voltage regulator devices (VRDs), and power pods, particularly for Intel® processor power performance requirements. Its design addresses the increasing need for low voltage, high instantaneous current simulation with fast di/dt loading, essential for modern processors. This instrument can replace multiple pieces of test equipment, including function generators, oscilloscopes, DVMs, and DC load banks, thereby saving bench space and cost.
