The reactive ALB-I-56DW unit is unique testing equipment for civilian and military applications. It allows an operator to perform an extensive load test and capture a real-time PDF data table to verify values simultaneously. It has been engineered by a new patented concept with a slide-in option to simply attach resistive 400 Hz AC. The unit has been engineered in accordance with STANAG 3456(7) and MIL-STD-704F standards and is intended for testing and diagnosing various 400Hz AC power sources with lagging power factor. All of the 400 Hz load banks are capable of running the GPU at full-load for an extended time period (max. 600 A load for 28.5 V DC versions). And in case of diesel driven GPUs, it is possible to run the GPU at full load for an extended time period, thus decarbonizing the engine. In addition, Dekal has also developed portable load banks for UPS systems and gensets for multiple applications. These models are rated either at 50Hz or 60Hz AC and may be further customized to requirements.
