The RONK 20 HP 3HE-AA Type AA is the ADD-A-PHASE static three-phase converter designed to handle hydraulic elevators, balers, and compaction equipment. Equipment whose loads vary more than 50% can run on this converter. Using Type AA on these loads is both effective and efficient, especially under light load conditions. Type AA requires no special starting circuits to “come up to speed” and runs very quietly, which is an advantage for indoor applications such as elevators.
The Automatic Adjusting ADD-A-PHASE is designed to handle the unique operating characteristics of hydraulic pump motors. The Type HE-AA is for hydraulic elevator applications, and the Type AA-HE is for hydraulic balers and compactors. The hydraulic pumps used in these applications generally put their motors under variable loads. These converters have an automatic adjusting circuit board which senses load and adjusts the current output (for better current balance to the motor) under these varying load conditions.
