Product Features
1. For pure resistive loads, the power factor
= 1; utilizes surface-mount resistor components with a resistance accuracy of ±3%; provides a pure resistive output that simulates real resistive load conditions, making it suitable for various AC power supply aging tests and performance evaluations.
2. Adjustable range, precise step resolution
Power Ratings: 100W,200W,200W,500W,1000W,2000W,3000W,3000W; minimum adjustment step: 100W; allows for flexible combination to achieve any power output between 0–10 kW.
3. Portable mobile design
The entire unit is equipped with a carrying handle and universal casters; its compact dimensions are ≤670×250×730 mm, its weight is ≤50 kg, enabling flexible movement on indoor floors.
4. Forced air cooling system
Equipped with 6 × 12038 cooling fans arranged in a directional airflow path from left to right, these fans continuously dissipate the heat generated by the resistors, enabling continuous online operation 24/7.
Application Scenarios
1. UPS and Inverter Power Supply Testing
Single-phase AC 220/250V inverter: full-load, half-load, and overload simulation tests; aging test
2.Energy storage inverters and portable energy storage power sources testing
Outdoor power supply and integrated energy storage system: continuous load-carrying capacity, discharge performance, and temperature rise test
3. Generator sets and small backup power supply load-bearing tests
Factory-load verification and periodic maintenance load testing for small single-phase gasoline/diesel generators
4. Aging test for charging pile AC modules and AC power supply modules
Power supply manufacturer's production line aging and reliability verification
Common Questions & Answers
Q1:What is the maximum voltage this load cabinet can withstand?
A:Rated AC 250V; the short-term maximum allowable voltage is 1.1 times the rated voltage (AC 275V); prolonged overvoltage will trigger the overvoltage protection; it is strictly prohibited to operate at voltages exceeding 250V for extended periods.
Q2:Can it operate continuously at full power of 10 kW for extended periods?
A: Supports 24/7 continuous operation; however, it requires proper environmental ventilation and an ambient temperature range of –10°C to 50°C, and the air inlets and outlets must not be blocked; for high-temperature environments, it is recommended to allocate additional power margin.
Q3: Can the load be fine-tuned to any power level? What is the minimum power level achievable for adjustment?
A:Minimum step size: 100W; gear settings can be freely combined; minimum load capacity: 100W; enables arbitrary power setting between 0–10 kW in increments of 100W.
Q4: What are the possible causes for a fan not rotating or for the equipment to trigger a high-temperature alarm?
A:
① The air intake and exhaust vents are blocked by debris;
② The ambient temperature is too high;
③ The fan is faulty; triggering the overheat protection will cause the load to be automatically unloaded; the unit must be shut down for cooling and troubleshooting.
