Test engineers in need of real world AC load simulation up to 4500W that provides highly accurate load levels over a broad range of values with integrated measurement  capability……The Chroma 63800  Series AC/DC Electronic Load is the  solution.

AC Loads vs Resistors

Resistors have typically filled a need to inexpensively load AC output devices; however using resistors presents disadvantages to the testing process:

  • Elaborate switching/resistor networks are needed to automatically change load levels
  • Resistors provide only unity power factor, thus do not simulate real world loads
  • Resistors impedance change with temperature so accurate load levels are nearly impossible to obtain
  • Current shunts and DMMs are also needed to measure actual load current and voltages

The Solution

Chroma’s 63800 series includes an industry-first circuit simulation mode allowing users to program circuit values directly with dimple power factor and crest factor values instead of approximating load conditions. Other advantages include:

  • Performs both AC and DC load simulation
  • Constant and Rectified Load Modes
  • Programmable In Rush Mode
  • Automatic Bandwidth Adjustment
  • Parallel / 3-Phase Control
  • Programmable Crest Factor and Power Factor
  • Integrated, accurate measurement capability for V, I, PF, CF, P, Q, S, F, R, Ip+/-, and THDv
  • Stability at 400Hz
  • Front Panel Controls

The Chroma 63800 Series AC/DC loads are designed for multiple-industry testing applications including uninterruptible power supplies, off-grid inverters, AC power sources and other power devices such as switches, valves, breakers, fuses, and connectors.
