3091LD Series AC Load

Product catalog summary

Overview: The 3091LD AC Load is designed for testing AC power generation equipment, such as UPS systems and AC sources, by providing precisely controlled, non-linear loads. It is suitable for testing active or passive current-carrying devices under real-world conditions, which traditional resistive load banks cannot simulate.

Key Features:

Front Panel Control: The device features a user-friendly, menu-driven front panel for quick testing in R&D settings.
Automated Testing: Supports IEEE-488 and RS232C remote control for integration into ATE test stations, using SCPI protocol for ease of test software development.
Power Levels: Capable of dissipating 3000 W of single-phase AC power, with options for higher power or three-phase applications through master/auxiliary configurations.
Multi-mode AC Electronic Load: Offers flexibility for a wide range of AC power test applications, including commercial, military, and avionics.
Built-in Measurements: Eliminates the need for additional test equipment, providing comprehensive measurement capabilities.

Operating Modes:

Constant Power (CP): Emulates constant power loads like switching power supplies.
Constant Resistance (CR): Replaces conventional resistive load banks with a programmable range from 2.5 to 1000 Ohms.
Constant Current (CC): Simulates both linear and non-linear loads for voltage regulation testing.
Constant Voltage (CV): Tests current source products by emulating a shunt regulator load.
Short Circuit (SC): Tests EUT short circuit protection with surge currents up to 300 Amps.

Specifications:

Power: 3000 W at 0-37°C; 2400 W at 38-50°C.
Current: 30 ARMS max, with peak/surge current up to 300 APEAK.
Voltage: 50 to 350 VRMS, with peak voltage up to 500 VPEAK.
Frequency: 45 to 440 Hz.
Protection: Includes over-current, over-voltage, over-power, and over-temperature protections.

Mechanical Specifications:

Dimensions: H: 8.75” (222 mm), W: 16.88” (429 mm), D: 25” (635 mm).
Weight: 74 lbs / 34 Kg.
Remote Sensing: Max. 2V drop between sense and load lines.

Interfaces: Supports GPIB and RS232C for remote control, with SCPI language for communication.

Additional Options: Includes options for AC line input, bench top model, master/auxiliary cable kit, and rack mount slides.
