DC Load Banks
DC load banks provide a controlled electrical load for testing direct-current power sources and distribution systems. They are used to verify performance, capacity, voltage stability, current delivery, and thermal behaviour of equipment such as batteries, chargers, DC power supplies, rectifiers, and related systems. A DC load bank typically combines resistive load elements with switching devices, measurement instruments, protective components, and a control interface. The design must account for the DC voltage range, current, total power, duty cycle, cooling method, and the nature of the source under test. DC interruption can be more demanding than AC switching because there is no natural current zero crossing, so switching components and protective devices must be selected specifically for the intended DC rating. Airflow, hot exhaust, clearances, and safe cable connections also require attention.
DC load bank: the battery bank discharges through the resistor elements, which turn the power into heat.
How it works
The load bank draws a controlled current from the DC source and converts the electrical energy into heat in its resistive elements. Load steps are selected to simulate defined operating conditions, while instruments monitor voltage, current, power, and other test parameters.
