Real World AC Load Simulation to 4500W
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.
