The 3091LD is designed to provide precisely controlled non-linear loads for testing AC power generation equipment such as UPS’s, AC sources, electrical switches and circuit breakers. The ability to simulate high crest factor and variable power factor AC load conditions provides an effective method of testing these and other AC products against real-world conditions and can significantly increase product reliability.

Traditionally, many of these products are tested using resistive load banks. This approach does not simulate real-world conditions such as switching AC inputs found in many AC powered products. This type of conventional testing does not fully exercise the equipment under test (EUT) against worst case operating conditions. High peak currents and low power factor loads can significantly impact the operating characteristics of a UPS or AC power product. Unless properly exercised, product defects may go undetected until a unit is used at a customer site, resulting in costly field returns.

Operating Modes

The 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. Specifically, the following modes can be selected:

Mode
Description

Constant Power
CP, This mode effectively emulates constant power loads sush
as switching power supplies.

Constant Resistance
CR, Emulates a conventional resistive load or power resistor.
A programmable range from 2.5 Ohms to 1000 Ohms covers a wide range of
applications. This mode can be used to replace conventional resistive
load banks.

Constant Current
CC
Provides a constant current load. This mode may be used to simulate
both linear (resistive) and non-linear (active) loads for voltage
regulation testing.

Constant Voltage
CV
This mode emulates a shunt regulator load and may be used to test
current source products.

Short circuit
SC
Test the short circuit protection mode of the EUT by providing a short
condition. The 3001LD can handle surge currents of up to 300 Amps for
up to 50 msec and sustained currents of 30 Amps in this mode of
operation. The low voltage cut-off of the load can be programmed from
50 Volts up.
