The NH Research 4600-36kW is a 36 kW AC electronic load that simulates diverse operating conditions for power conversion device testing. It emulates linear and non-linear loads with programmable crest factor and power factor control, making it ideal for validating UPS systems, AC sources, inverters, switches, circuit breakers, fuses, and connectors under dynamic and transient conditions.
Technical Specifications
• Power Capacity: 36 kW
• Voltage Range: 50–350 V RMS (L-N)
• Current Range: Up to 360 A RMS
• Frequency Range: 45–440 Hz
• Available Power Levels: 3, 6, 12, 18, 24, and 36 kW (field expandable in 3 kW increments)
• Configurations: Single and three-phase
– Emulation & Measurement
The load operates in seven modes: Constant Current, Constant Resistance, Constant Voltage, Constant Power, Short Circuit, Unity Power Factor, and Complex Non-Linear Waveform. Internal measurement accuracy reaches 0.1% for voltage, 0.2% for current, and 0.5% for true power (applicable above 10% of range). The instrument measures frequency, voltage, peak voltage, current, peak current, crest factor, apparent power, true power, peak power, reactive power, power factor, and resistance.
– Key Features
• User-Defined Waveforms: Graphical editor for custom waveforms, including spikes, dropouts, and asymmetrical inflections
• 100-Step Multi-Mode Macros: Rapid parameter adjustments executable as single shots or loops
• PC Softpanel: Windows-based GUI for control, measurement display, and waveform visualization
• LabVIEW and IVI Driver Support: Direct PC integration for automated test sequences
• Auto-Check: Validates setting compatibility with load capabilities
• True Short Circuit Mode: Tests UUT protection response
• Field Upgradeable: Expand in 3 kW increments
– Typical Applications
UPS system validation, inverter performance testing, AC source characterization, power conversion device qualification, and transient protection evaluation.
– Compatibility & Integration
PC control via LabVIEW and IVI drivers enables integration into automated test systems. Softpanel operation requires 3 GHz processor and 512 MB RAM minimum.
