Chroma 63803

 Chroma 63803 AC & DC Electronic Load      Chroma's 63803 AC & DC Electronic 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. The state of the art design uses DSP technology to simulate non-linear rectified loads with its unique RLC operation mode, which improves stability by detecting the impedance of the UUT and dynamically adjusting the load's control bandwidth to ensure the system's stability.    Included in the Chroma 63803 AC & DC Electronic load are built-in 16-bit precision measurement circuits to measure the steady-state and transient responses for true RMS voltage, true RMS cur, true power(P), appa power(S), reactive power(Q), crest factor, power factor, THDv and peak repetitive cur. There are two unique operating modes for AC load simulation and DC load simulation includes four load modes.  A special DC Rectified mode is included to simulate the loading behavior of distributed inverters. This unique load mode makes the Chroma 63803 load ideal for Fuel Cell, PV module/array and Battery testing. Specifications for the Chroma 83603 AC & DC Electronic Load Include: The Chroma 63802 and Chroma 63804 are also available
