The California Instruments 3091LD AC electronic load is designed to provide precisely controlled, non-linear loads for testing AC power generation equipment such as Uninterruptible Power Supplies (UPS) and AC sources. In addition, any active or passive current carrying devices such as switches, circuit breakers, fuses, connectors and power semiconductors can be tested. Each 3091LD is capable of dissipating 3000 W of single phase AC power. For higher power or three phase applications, a 3091LD master unit can be combined with one or more auxiliary 3091 units.
The California Instruments 3091LD can simulate high crest factor and variable power factor load conditions. This provides an effective method of testing AC products against real-world conditions and can significantly increase product reliability. The operating modes include: constant power, constant resistance, constant current, constant voltage, and short circuit. The California Instruments 3091LD can be used to emulate a wide variety of AC load conditions to support real-world testing and evaluation of UPS and AC source products.
