AC ELECTRONIC LOADS

PROGRAMMABLE AC LOAD

• 3 kW / 30 A modules expandable to 180 kW
• Power and crest-factor programmability
• 12 built-in, high-accuracy measurements
• Graphical user interface and LabVIEW™ drivers

APPLICATION

The 4600 Series AC Electronic Loads are intended for applications that require the entire range of non-linear loading in order to thoroughly test AC-output power conversion devices. This includes such items as uninterruptible power supplies (UPSs) and inverters. The benefits of such a wide range of load control is to assure product performance under simulated "real-world" operating conditions.

NON-LINEAR LOADING

The advantages of testing with a programmable, non-linear load (i.e., any combination of power and crest factor) are substantial. The most significant being the ability to rapidly test products at the most severe loading conditions that could be encountered in the field. The other major benefit is the ability to instantly switch over to a different set of loading conditions when testing new models. With such versatility, a higher level of product quality is assured and manufacturing throughput is increased.

BROAD OPERATING ENVELOPE

To cover a wide range of UPS and inverter power levels, the 4600 Series AC electronic loads can be paralleled up to 62 instruments. All units operate from 50 to 350 VAC-input and in several emulation modes such as constant-current, constant-voltage, constant-resistance, constant-power as well as short-circuit.

A "ONE- BOX" TEST SOLUTION

With a PC controller, everything needed to test most AC-output products is contained within the 4600 Series AC Electronic Load. In addition to the flexible load control, twelve high-accuracy measurements include: voltage, current, peak-current, frequency, crest-factor, power-factor and true power. Even the real-time voltage, current and power waveforms are displayed on the PC soft panel. This ability to make all measurements internally eliminates multiple, external stand-alone instruments plus associated signal matrixing and interconnect wiring. In this manner, the 4600 Series AC electronic load provides for a more compact, less costly and considerably faster test solution.

SYSTEM OR MANUAL APPLICATIONS THROUGHOUT THE ENTERPRISE

The applications for the 4600 Series AC electronic loads are many. While primarily designed for final functional test within an automatic test station, such as the Model 5500 Universal UPS Tester, the AC load can be used with just a PC for engineering design verification test, incoming quality inspection and returned unit repairs. To facilitate rapid integration and popular programming language compatibility, the 4600 Series AC load is supplied with a PC-hosted graphic user interface plus LabVIEW™ drivers.
