The Chroma 63800 Loads can simulate load conditions under high crest factor and varying power factors with real time compensation even when the voltage waveform is distorted. This special feature provides real world simulation capability and prevents over stressing resulting in reliable and unbiased test results.
Chroma’s 63800 Series AC/DC Electronic Loads include built-in 16-bits precision measurement circuits to measure the steady-state and transient responses for true RMS voltage, true RMS current, true power(P), apparent power(S), reactive power(Q), crest factor, power factor, THDv and peak repetitive current. In addition to these discrete measurements, two analog outputs, one for voltage and one for current, are provided as a convenient means of monitoring these signals via an external oscilloscope.

| Optional Graphic User Interface |
| Benefits |
|
| AC Electronic Load Simulation Operating Modes | Constant Load Modes allow users to set the following operating modes: CC, CR and CP mode. The CC and CP modes in this category allows users to program PF, CF, or both.
The power factor range is limited based on crest factor programmed.
If the programmed PF is positive then the current will lead the voltage waveform.
When PF is set negative, the current will lag the voltage waveform.
The 63800 AC & DC Electronic Load is also capable of simulating non-linear rectified loads for a wide range of testing applications, with three load modes available for rectified load simulations: RLC, CP and Inrush Current.
|
| DC Load Simulation | Chroma’s 63800 DC load simulation includes four load modes: constant current, constant resistance, constant voltage and constant power as depicted below. CC, CR, CP mode can be used for regulated voltage power supply testing.
Many inverter designs, although its input is DC, show an input current and will show rectified pattern.
This unique load mode makes the Chroma 63800 load ideal for Fuel Cell, PV module/array and Battery testing.
