Applications
A 500kW 400V AC load bank is a high-power testing device that simulates electrical loads in a controlled environment, which provides a safe, repeatable, and measurable method to test and validate power sources and distribution systems before being deployed in mission-critical applications. It is mainly used in the following applications:
● Conducting acceptance tests after installation or maintenance
● Checking generator stability during step load changes
● Verifying inverter output capacity
● Preventive maintenance to ensure backup reliability
● Load transfer testing between utility and backup power
● Ensuring cooling and distribution systems meet demand
● Absorbing excess power for grid stability and demand response
● Compliance testing with DNV, ABS, Lloyd's and other standards
● Quality assurance before delivery to customers
