A container load bank is a large-scale, portable testing device housed within a shipping container. These load banks are designed to simulate real electrical loads by applying a controlled electrical load to power sources, such as generators, turbines, and UPS systems, to test their performance under various conditions. The containerized design allows these load banks to be easily transported and deployed to different locations, making them highly versatile for various applications.
Container load banks can be configured as resistive, reactive, or a combination of both (resistive/reactive), depending on the specific testing requirements. They are available in different capacities, ranging from a few hundred kilowatts to several megawatts, making them suitable for testing a wide range of power systems.

Rated voltage/frequency | AC three-phase four wire AC400V/690V-50Hz |
Maximum power | 1800kW Explanation: 1. The resistance part has been considered overloaded by 1.67 times. (Calculated based on rated power of 1200kW) 2. When the input voltage is lower than the rated voltage, the load cabinet gear changes according to Ohm's law. |
Compatible voltage/frequency | When the corresponding power is AC400V/50Hz, it is used through AC690V load: Satisfy active power of 1100kW, power factor PF=0.8 (lag), and meet active power overload of 1.1 times . |
Minimum step | 1kW |
Unbalanced gear | At AC690V/50Hz：the unbalanced resistive power meets the requirements of single-phase 500kW, two-phase 333kW, and the minimum gear is 1kW. At AC400V/50Hz： the unbalanced resistive power meets single-phase 167kW, two-phase 250KW, and the minimum gear is 1kW. |
