Product Introduction
The High Voltage Load Resistor Cabinet is a premium power testing device specifically designed for high-voltage, high-power applications. Its primary function is to deliver a pure, stable, and controllable resistive load for testing high-voltage generator sets, UPS systems, power transformers, new energy equipment (e.g., photovoltaic inverters and energy storage converters), and high-voltage frequency converters. This load simulates real-world operating conditions, enabling factory testing, acceptance testing, maintenance trials, and performance validation.

Core Features
High-Voltage Insulation and Safety Design
Professional Insulation: The resistor elements, terminals, and internal structure are constructed from high-strength insulation materials with a high-standard insulation design. This effectively withstands high-voltage surges, prevents creepage and flashover, and ensures inherent safety.
Precise Load Simulation and Control
High-Precision Non-Inductive Resistors: The High Voltage Load Resistor Cabinet employs specially engineered alloy resistors in strip or grid configurations with ultra-low inductance, eliminating inductive reactance effects on test accuracy. This ensures a pure resistive load in AC environments and delivers precise, reliable test data.
Powerful Heat Dissipation System
Efficient Cooling Solution: Depending on power requirements, either forced-air cooling (using high-power centrifugal fans) or a water-cooling system is implemented. Scientifically optimized air/water ducts ensure rapid, uniform heat removal, maintaining safe operating temperatures.

Typical Application Scenarios
High-voltage Generator Set Testing: High Voltage Load Resistor Cabinets are used for power verification, load capacity testing, voltage and speed regulation characteristics testing, and sudden load/unload testing of backup generator sets in ships, power plants, and data centers.
Data Center Power Testing: Full-load burn-in testing and performance acceptance testing of high-voltage UPS (e.g., 380V/400V/480V input and output) and HVAC systems.
New Energy Industry: Load units are used for efficiency testing, MPPT tracking testing, and low voltage ride-through (LVRT) testing of photovoltaic inverters and power storage converters (PCS).

Installation Notes
When installing a High Voltage Load Resistor Cabinet, please pay attention to the following three points:
Ventilation and heat dissipation: Install in a spacious and well-ventilated area with ample space around the cabinet to ensure proper heat dissipation.
Reliable grounding: Grounding must be performed by a professional electrician to ensure proper safety.
Professional wiring: Wiring must be performed by a licensed electrician using appropriate cables, ensuring all connections are secure and correct.
