Description
Overview
The AMETEK California Instruments 3091LD is a single-phase AC electronic load designed to provide precisely controlled, non-linear loads for testing AC power generation equipment, Uninterruptible Power Supplies (UPS), and AC sources. Each unit can dissipate 3000 W of AC power and can be combined with auxiliary units for three-phase or higher power applications.
Key Features
- 3000W continuous power capacity (0-37°C); 2400W (38-50°C)
- 13 kW peak power capability (up to 20% duty cycle)
- 30 ARMS continuous current; 300 APEAK for 50 ms surge
- Voltage range 50-350 VRMS with 500 VPEAK maximum
- Operating frequency 45-440 Hz
- Programmable load modes: constant power, constant resistance, constant current, constant voltage, short circuit
- Simulates high crest factor and variable power factor conditions
Applications
- Testing Uninterruptible Power Supplies (UPS)
- AC source and power generation equipment evaluation
- Testing active and passive current-carrying devices (switches, circuit breakers, fuses, connectors)
- Power semiconductor testing
- Real-world load condition simulation
