Product Features
Core Positioning: A continuously adjustable pure resistive load bank (100 W–10 kW), specifically designed for "load testing + aging tests"; ready to use upon connection.
Wide range of adjustment
100W–10kW continuous stepless adjustment with a minimum step of 100W; selectable power levels (100W/200W/500W/1kW/2kW/3kW...), enabling comprehensive testing across all power ranges in a single operation.
Pure resistive load, power factor 1
Resistive load with a power factor close to 1 simulates real-world electrical operating conditions, making the test data more reliable.
High accuracy
Resistance accuracy: ±3% (sheet resistors); parameters are reproducible and traceable.
Digital display – intuitive
Real-time display of voltage, current, and power – the load status is clear at a glance, eliminating the need for external instruments.
Triple Protection
Overheating alarm + Overvoltage protection (upper limit set at 1.1 times the rated voltage) + Emergency stop button – immediately cuts off power upon detection of an abnormality, protecting both the monitored equipment and the load cabinet itself.
Application Scenarios
Power supply products – Aging/Load Testing:
Switching power supplies, adapters, chargers, and battery discharge tests; subjected to prolonged full-load or stepwise load conditions to verify stability and temperature rise.
UPS/Inverter Testing:
Verify the rated output capacity and overload capacity of the uninterruptible power supply (UPS) and inverter.
Generator/Generator Set Testing:
Perform trial run, load acceptance test, and break-in operation using a pure resistive load.
Inverter / Servo Driver:
Use in conjunction with braking/feedback load simulation to verify the reliability of the braking unit.
Common Questions & Answers
Q1: What is this load cabinet used for?
A: It is an adjustable resistive load testing device that simulates real-world electrical loads. It is used to perform load, aging, and overload tests on power supplies, UPS systems, inverters, generators, and other equipment, to verify whether their output capacity meets the required standards and whether they are reliable.
Q2: Can the power be adjusted? What is the minimum adjustable value?
A: Yes. The power range is continuously adjustable from 100 W to 10 kW with a minimum step of 100 W; finer step adjustments can be made using a combination of DIP switches.
Q3: Is this a three-phase or single-phase unit? Can it be connected to three-phase equipment?
A: This is a 10 kW single-phase AC220V model (rated voltage: AC220V; auxiliary power supply: AC220V,50 Hz). To power three-phase equipment, please select the three-phase model; please feel free to contact us for customized solutions tailored to your needs.
Q4: Can it operate at full load for extended periods? Will it overheat?
A: Yes. With forced air cooling combined with six fans for heat dissipation, it supports continuous 7×24-hour online operation; it is also equipped with an overheating alarm, overvoltage protection (upper limit set at 1.1 times the rated voltage), and an emergency stop function – any exceedance will trigger an automatic alarm or shut down the device; under normal operating conditions, it is unlikely to overheat.
Q5: What is the accuracy? Is the measured value reliable?
A: The resistance accuracy is ±3%; voltage, current, and power are displayed digitally, and load-related data can be read directly – meeting the requirements for the vast majority of factory acceptance tests and R&D testing scenarios.
