Product Features
Rack-mount portable design:
Adjustable step pure resistive load:
Mandatory forced air cooling:
Two 12038 fans, with air flowing in from the front and out from the rear, ensuring efficient heat dissipation during long periods of high-power operation.
Real-time digital display monitoring:
The panel directly displays the voltage, current and power, allowing for intuitive reading of the test data. The manual circuit breaker control makes the operation simple.
Application Scenarios
UPS Uninterruptible Power Supply, Inverter, AC Power Module's Load Testing, Aging Test, Discharge Test
Verification of output capacity of small-scale power generators and backup power sources, as well as performance testing of loads
Factory aging and reliability tests for energy storage converters, charging station power modules, and industrial switching power supplies
Laboratory power supply research and testing, university electrical teaching experiments, quality inspection of electrical equipment at factory exit
Common Questions & Answers
Q1: Is this load cabinet purely resistive load? What is the power factor?
A: Yes, it is purely resistive load. The power factor is 1, and it does not generate reactive power. It is suitable for AC power supply load testing.
Q2: What is the minimum power level that can be adjusted? How is the power adjusted?
A: The minimum power is 100W. It can be adjusted through the manual circuit breaker settings on the panel. The minimum step is 100W, and the maximum is 5KW.
Q3: Can it operate at full power of 5KW continuously for a long time?
A: Yes, the equipment supports 7*24h continuous operation, but it is necessary to ensure good ventilation and normal operation of the fans; the environmental temperature must not exceed 50℃.
Q4: What does IP20 mean for the equipment's protection level? Can it be used outdoors?
A: IP20 is only for indoor use. It prevents fingers from touching the internal energized components and does not offer waterproof or dustproof protection. It is prohibited for use in outdoor, humid, and dusty environments.
Q5: How to reset after the load cabinet protection is triggered (due to overheating / overvoltage)?
A: Disconnect the input power supply, shut down the machine to cool down, investigate the cause of the abnormal voltage, and once the fault is eliminated, restart the machine to restore normal operation.
