DC load banks simulate electrical loads and are used for testing and maintaining large batteries and battery systems, rotary UPS equipment, DC motors and generators, as well as other DC power supplies and equipment. The 0-500amp DC load bank is compact, portable, and lightweight. At select voltages (i.e. 24V, 48V, & 52V) is ideal for providing a temporary load for field servicing and testing up to 48 volt DC power supplies.
