NH Research 9430-8 Regenerative AC Load - 4-Quadrant
The NH Research 9430-8 is a state-of-the-art 4-Quadrant Regenerative AC Load designed to meet the rigorous demands of electrical testing. Capable of simulating a wide range of linear and non-linear loads, this advanced equipment is ideal for testing Uninterruptible Power Supplies (UPSs), AC sources, inverters, rectifiers, switches, circuit breakers, and fuses. The NH Research 9430-8 enhances your testing capabilities with its ability to return power back to the facility mains instead of dissipating it as heat, offering a more sustainable and efficient testing solution.
Key Features:
- 4-Quadrant Operation: The NH Research 9430-8 can operate in all four quadrants, allowing for bi-directional current flow. This feature enables the simulation of reverse current from inductive or capacitive loads during specific parts of the AC cycle, accurately replicating real-world reactive electrical power flows.
- HIVAR® Design Feature: The innovative HIVAR® design supports testing high reactive loads while maintaining true power efficiency. This allows for reactive power (VARs) inputs up to 2.6 times the rated true power in watts. For example, a 12kW load can support up to 31.5kVA.
- Emulation Modes: The NH Research 9430-8 supports multiple emulation modes for versatile testing. These include:
- Constant Current (CC) Mode: Provides a consistent current draw, perfect for linear, non-linear, and regulation testing.
- Constant Resistance (CR) Mode: Emulates a power resistor with a unity power factor.
- Constant Power (CP) Mode: Simulates loads like switching power supplies.
- Constant Apparent Power (CS) Mode: Represents both real and reactive power in a vector quantity.
- Constant RL (CRL) Mode: Mimics a resistive load with an inductive component, such as motors.
- Regenerative Return of Load Power: The 9430-8 regenerates over 90% of the power back to the facility, providing significant energy savings. Continuous load testing can recoup the purchase cost within 2-3 years, while intermittent usage still yields substantial savings and contributes to optimized facility energy usage.
