NH Research 4600 Programmable AC Electronic Load

NH Research 4600 Programmable AC Electronic Load

Description

The NH Research 4600 Programmable AC Electronic Load is designed for test applications that require linear and non-linear AC loading in several emulation modes with Power and Crest Factor control. This programmable versatility allows testing with a wide variety of potential field operating conditions to assure unit-under-test (UUT) reliability. Products tested include uninterruptible power supplies (UPS), AC sources, inverters, switches, circuit breakers, fuses and connectors.

Emulation Modes

To provide testing under the broadest range of loading conditions, the AC Electronic Load offers 7 different emulation modes. Constant Current (CC) mode provides current to be drawn constantly, making it suitable for non-linear, linear and regulation loading. While Constant Resistance (CR) mode allows the electronic load to emulate a power resistor, Constant Voltage (CV) allows emulating a shunt regulator. Constant Power (CP) mode emulates a constant-power load such as a switching power supply. The Short Circuit (SC) mode allows the electronic load to test the UUT’s short circuit protection capability. Unity Power Factor (UPF) mode causes power factor to be as close as possible to unity, useful when the input voltage is non-sinusoidal. The new Complex Non-Linear Waveform (CNL) Mode allows the user to define the waveform to prevent UUT current overstressing in the event of a voltage collapse. These comprehensive capabilities provide the user almost every conceivable AC loading condition.

High Accuracy Measurements

The AC Electronic Load internally measures frequency, voltage, peak voltage, current, peak current, crest factor, apparent power, true power, peak power, reactive power, power factor and resistance by combining high-resolution measurements with precision ranging. The ability to make internal measurements eliminates multiple external measurement instruments resulting in a more compact, less costly and considerably faster test system.

User-Defined Waveforms

The AC Electronic Load has the ability to control current through a user defined waveform. The waveform is created by a powerful graphical editor that facilitates starting with a straight line or modifying a generated waveform based on current, power and crest factor. The graphical editor includes an auto-check feature to ensure the settings are compatible with each other and within the capabilities of the electronic load. It also supports waveform smoothing, symmetrical and asymmetrical waveform creation. With this editor, waveforms can be quickly created to duplicate complex transient conditions. This would include adding asymmetrical inflections, inserting transient anomalies such as spikes and dropouts, and just about anything else that can be drawn as a single-cycle waveform.
