Very high capacity electrical loads, for testing, maintenance and performance analysis of large AC power systems can be formed using the Simplex Titan Load Bank. It is a self-contained, semi-portable unit providing resistive and inductive loads to 1500KVA at 0.8 power factor. It can be applied singly or in systems of multiple units paralleled to achieve virtually any total capacity desired. Pictured is a Titan 550 Load Bank.
The Titan is weatherproof and intended for outdoor use. It can be moved using a forklift or a crane, or it can be mounted on a trailer. Trailer installations can accommodate multiple units, within the weight capacity of the trailer.
