Power Simulation: Single unit power typically ranges from 4kW to 30kW, supports AC/DC dual modes, and allows precise power adjustment.
Thermal Simulation: Heating characteristics and air volume are highly consistent with real servers, accurately replicating computer room heat density.
Flexible Deployment: Modular, stackable, and parallel-operable, quickly adapting to test scales from small computer rooms to hyperscale data centers. - Dec 17, 2025Sunwin Load Bank: The Professional Cornerstone for Verifying Power ReliabilityIn the critical field of power security, Uninterruptible Power Supplies (UPS) and generator sets form the "lifeline" of infrastructure. Their designed performance and operational capability must be validated through scientific and rigorous means. Sunwin, as a professional provider of intelligent power supply testing equipment, deeply understands the core value of the load bank in this process—it is not merely a testing tool but the professional cornerstone and performance benchmark** for measuring power system reliability.
Typical applications of load bank in power testing
1. Power generation equipment testing Generators (diesel/gasoline/gas generators):
Load capacity verification: Gradual test from no-load to rated load, detection of voltage, frequency stability and recovery characteristics.
Overload capacity test: Short-term overload (such as 110% rated load) to verify the response speed of the protection device.
Parallel operation test: When multiple generators are connected in parallel, power is distributed through the load bank to detect synchronization and load balancing capabilities.
New energy power generation (photovoltaic inverters, wind power converters): Simulate grid impedance characteristics to test the inverter's islanding effect protection, harmonic suppression capability and grid-connected stability.
2. Power system testing UPS (uninterruptible power supply):
Full load/half load test to evaluate battery life, voltage fluctuations at the moment of switching and recovery capabilities.
Load distribution balance test of redundant UPS systems.
Battery pack: Discharge test: Use constant current load bank to simulate real discharge scenarios, detect battery capacity, internal resistance and consistency, and avoid "false power" problems.
Switching power supply / DC power supply: Load adjustment rate test: Stability of output voltage when load changes (such as load jump from 0% to 100%).
3. Power grid and distribution system test
Substation / distribution transformer: No-load loss and load loss test (equivalent load method) to evaluate energy efficiency level.
Short-circuit impedance simulation to test the accuracy of the action threshold of the protection device.
Harmonics and power quality: Non-linear load bank (such as rectifier, inverter simulation) is used to test grid harmonic pollution and evaluate the filter effect.
4. Equipment aging and reliability test
Aging test: Run the power supply equipment at full load for a long time to expose early faults (such as poor heat dissipation and component aging).
Environmental adaptability: Use a temperature and humidity chamber to test the changes in load characteristics under high and low temperature and humid and hot environments.
