Description
Overview
The Chroma 63804 is a programmable AC/DC electronic load designed to simulate load conditions under high crest factor and varying power factors with real-time compensation, even when voltage waveforms are distorted. With 4500W power rating and 45 Arms maximum current, it operates across a 50-350 Vrms voltage range and supports both AC (45-440 Hz) and DC modes.
The unit includes built-in 16-bit precision measurement circuits for steady-state and transient response analysis, including true RMS voltage and current, real power (P), apparent power (S), reactive power (Q), crest factor, power factor, and THD. Dual analog outputs allow external oscilloscope connection for voltage and current monitoring.
Key Features
- Real-time load compensation for distorted waveforms and high crest factor conditions
- Master/Slave parallel control for synchronized multi-load operation
- Programmable slew rate for dynamic load transient simulation
- Optional graphical user interface for enhanced ease of use
- 16-bit precision measurement circuits for accurate diagnostics
Applications
- Constant load mode testing (CC, CR, CP) with programmable power factor and crest factor
- Rectified load simulation for non-linear load testing and characterization
- Regulated voltage power supply testing and validation
- Fuel cell, photovoltaic module, and battery pack testing
- Inverter design validation and dynamic response characterization
Specifications
| 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. |
