High capacity load testing of generators, periodic reliability exercise of standby generators, regenerative power absorption of inertial motors with reverse power protection of generators and other load bank applications are achieved with the Simplex Neptune Load Bank. The unit capacity range of the Neptune is 200-650KW, resistive, unity power factor. Reactive units (inductive or capacitive) are also available.
The Neptune is a single or dual voltage load bank suitable for all common 60, 50, and 400 hertz voltages up to 600V.
The standard configuration (Type 3R weatherproof) includes the UL tested and listed exhaust hood. When installed indoors a duct flange is provided and the load bank is connected to a customer supplied exhaust duct.
