    AI Overview
    A 400kW / 500kVA combined resistive and inductive (reactive) load bank is a specialized, high-capacity testing unit designed to test generators, UPS systems, and power supplies at a 0.8 lagging power factor. These units, such as the Keypower KPLB-500, allow for precise, step-controlled load adjustments to verify full KW and kVAR capacity. 
    Key Specifications & Features 
    • Capacity: 400kW resistive and 500kVA (300kVAR) inductive capacity.
    • Power Factor: Typically rated for 0.8 lagging.
    • Voltage: Commonly available for 480VAC 3-phase or 240/480 VAC.
    • Cooling System: Forced air cooling with high-capacity blowers (e.g., ~10,700 CFM).
    • Control: Digital metering and step-load control (e.g., 5kW increments).
    • Safety Protection: Automatic shutdown for high temperature, airflow failure, and over-voltage.
    • Structure: Heavy-duty, portable enclosure with casters or forklift channels. 
    Applications 
    • Generator Testing: Prevents wet-stacking by testing generators at full-rated power, often required for diesel sets designed at 0.8 PF.
    • UPS Testing: Simulates true load conditions for Uninterruptible Power Supplies, including inductive loads.
    • Industrial Maintenance: Ideal for data centers, hospitals, and shipyards requiring on-site testing. 
    Common Manufacturers & Rental Sources 
    • Keypower: Offers industrial-grade portable combined resistive/inductive units.
    • Trystar: Manufactures stationary and portable resistive/reactive units.
    • Sunbelt Rentals: Provides 400kW rental units.
    • Avtron/Simplex: Known for specialized generator testing load banks. 
    These units allow for comprehensive testing of complex loads, ensuring systems meet performance requirements under realistic operating conditions.
