Product Description
California Instruments 3091LD is a high-performance programmable AC electronic load. The 3091LD is specifically designed for testing AC power generation equipment (such as uninterruptible power supplies UPS, AC power supplies), as well as switches, circuit breakers, fuses, connectors, and power semiconductors with active or passive current-carrying devices. It can provide precisely controlled non-linear loads, simulating real-world high peak factor and variable power factor load conditions. A single unit can dissipate 3000W single-phase AC power. Through the main/auxiliary configuration, it can be expanded to higher power or multi-phase applications. The voltage range is 50-350Vrms, the frequency range is 45-440Hz, and it is suitable for commercial, military, and avionics fields.
Product Features
Multi-mode load simulation: Supports various working modes such as constant current, constant power, constant impedance, constant voltage, and short circuit, which can precisely simulate various real load scenarios.
Wide power and voltage range: Power 3000W (0-37℃) / 2400W (38-50℃), voltage 50-350Vrms, frequency 45-440Hz, peak power up to 13kW (20% duty cycle), peak current 300Apeak (50ms).
Programmable peak and power factor: The peak factor can be adjusted between 1.4142-4.0, and the power factor supports 0-1 leading or lagging, capable of simulating complex load conditions in the real world.
Built-in measurement and analysis: Equipped with rich built-in measurement functions such as voltage, current, power, frequency, peak factor, power factor, etc. It can also perform harmonic analysis and waveform acquisition without additional test equipment.
