NH Research 9430-4 Regenerative AC Load, 4-Quadrant, 4kW

NH Research 9430-4 Regenerative AC Load: 4-Quadrant Testing Solution

Introducing the NH Research 9430-4 Regenerative AC Load – a state-of-the-art testing device meticulously engineered for versatile applications in both linear and non-linear load simulations. With its advanced capabilities, the 9430-4 is the ideal solution for testing uninterruptible power supplies (UPSs), AC sources, inverters, rectifiers, circuit breakers, and fuses.

Key Features:

• 4-Quadrant Operation: The NH Research 9430-4 stands out with its ability to operate in all four quadrants, enabling bi-directional load simulation. This feature adeptly handles reverse currents from inductive or capacitive loads, accurately replicating real-world reactive power flows during AC cycles.
• HIVAR® Design Feature: The innovative HIVAR® technology allows for testing high reactive load input power without compromising true power measurement. This unique feature supports reactive power (VARs) up to 2.6 times greater than true power, offering 12kW rated loads up to 31.5kVA.
• Multiple Emulation Modes: The 9430-4 accommodates a wide array of loading conditions through several Emulation Modes. Choose from:
  • Constant Current (CC): Ensures a constant current draw.
  • Constant Resistance (CR): Emulates a power resistor at unity power factor.
  • Constant Power (CP): Ideal for simulating switching power supplies.
  • Constant Apparent Power (CS): A vector quantity combining real and reactive power.
  • Constant RL (CRL): Simulates a resistive load with an inductive element.
• Regenerative Power Return: The NH Research 9430-4 is designed for efficiency, returning over 90% of the sink power back to the facility. This remarkable feature can lead to substantial savings, with the potential for recovery of purchase costs in just 2-3 years, contributing to a more comfortable work environment and reduced air conditioning needs.
