Portable Load Banks

Portable Load Banks

Portable load banks are movable test-load systems intended for commissioning, maintenance, and troubleshooting at different locations. They may be designed for AC or DC use and can be built in a compact wheeled, rack-mounted, or transportable enclosure depending on the power level and site conditions. Portability does not remove the need for adequate cooling, safe electrical connection, protective devices, and clear operating procedures. The unit must be selected for the source's voltage, phase, current, frequency, power, and required load steps. Weight, dimensions, lifting points, wheels, cable storage, and the availability of a suitable power connection influence field usability. Some units are intended for indoor use, while others require a specific environmental or weather-protection rating. The duty cycle and ambient temperature should be confirmed before using a portable unit for extended testing.
