NHR 9430-12 Regenerative 4-Quadrant AC Load

The NHR 9430-12 is a 4-quadrant AC load that is regenerative and current-regulated, and it is made for accurate and versatile power testing. It can work in single, split, or three-phase configurations, giving users the ability to model a large range of actual loads. With a frequency range of 30Hz to 880Hz, the 9430 is perfect for testing a variety of power systems, including UPSs, inverters, circuit breakers, rectifiers, and fuses. It can handle input voltages of 10 to 175 VRMS and 350 VRMS (L-N) for AC applications. During testing, it may return over 90% of the load power to the facility mains, which results in significant energy savings.

A large selection of programmable modes, such as Constant Apparent Power (CS), Constant Current (CC), Constant Resistance (CR), Constant Power (CP), and Constant RL (CRL), are available with the NHR 9430-12. It is capable of simulating loads that vary from resistive to inductive components, as well as from linear to non-linear. Having a true power rating of 12 kW, a maximum apparent power rating of 31.5 kVA, and current limits of up to 90A per channel, it can withstand harsh load simulations. A maximum power of 12 kW can be achieved in DC mode, where the input voltage spans from 10V to 400VDC.

Its bi-directional 4-quadrant operation is one of its most notable qualities. By doing so, the NHR 9430-12 can replicate the reverse currents produced by capacitive or inductive loads and return electricity to the unit being tested (UUT). It is perfect for testing reactive electrical power flows in low power factor applications because of its special ability. Also, the instrument has a sophisticated HIVAR® design that provides reactive power up to 2.6 times the true power, enabling high reactive load testing without compromising genuine power output. Because of this, the 9430 is a great choice for testing apparatus that needs a high apparent power.

The NHR 9430-12 can be operated externally with a Windows-based PC or internally using an integrated touch panel interface. With its integrated digital measuring system, which offers high-resolution waveform digitization and extensive power analysis capabilities, there is no need for extra external equipment like oscilloscopes or power analyzers.
