Introducing the NH Research 9430-36 Regenerative AC Load: Unmatched Performance in Power Testing
The NH Research 9430-36 is a state-of-the-art 4-Quadrant Regenerative AC Load designed for intricate testing of various electrical components. Its advanced features make it the perfect tool for evaluating uninterruptible power supplies (UPS), AC sources, inverters, rectifiers, switches, circuit breakers, and fuses. This versatile device can simulate virtually any linear or non-linear load, enhancing your testing capabilities significantly.
Exceptional 4-Quadrant Operation
One of the standout features of the NH Research 9430-36 is its 4-quadrant operation. This bi-directional capability allows for a comprehensive load simulation that surpasses traditional 2-quadrant AC loads. The device can accurately recreate the reverse current effects created by inductive or capacitive loads, enabling power to flow back to the unit under test (UUT) during specific AC cycles. This unique ability ensures realistic simulation of reactive electrical power flows, closely mirroring real-world conditions.
Innovative HIVAR® Design
The NH Research 9430-36 features an advanced HIVAR® design that enables high reactive load input power testing without the typical reduction of true power (Watts). This allows reactive power (VARs) testing up to 2.6 times the true power rating, making the device ideal for high-performance applications. For instance, with a load rated at 12kW, the unit can also handle up to 31.5kVA of apparent power, showcasing its robust capabilities.
Comprehensive Emulation Modes
To accommodate a wide range of testing scenarios, the NH Research 9430-36 comes with multiple Emulation Modes:
- Constant Current (CC) Mode: Maintains a steady current draw for various loading conditions.
- Constant Resistance (CR) Mode: Simulates a power resistor with unity power factor.
- Constant Power (CP) Mode: Emulates loads such as switching power supplies.
- Constant Apparent Power (CS) Mode: Represents a load with both real and reactive power components.
- Constant RL (CRL) Mode: Mimics a resistive load with inductive characteristics, akin to a motor.
Regenerative Return of Load Power
One of the most significant advantages of the NH Research 9430-36 is its ability to return over 90% of the power back to the facility, offering substantial energy savings. In scenarios involving continuous load testing, the device can recover its initial investment in as little as 2 to 3 years. For intermittent loads, the regenerative return still provides considerable savings, contributing to a more sustainable work environment while reducing the need for extensive facility power upgrades.
