2U x 19” stainless steel cradle with 3 x BAP 65F modules

This modular, heavy-duty DC/DC converter system is built with three 1000W BAP 65F power modules assembled in a 2Ux19” stainless
steel, rack-mount cradle (CR 2U/19-3). The cradle is constructed with high-grade stainless steel and mechanical features that allow for
easy insertion and removal of the BAP 65F modules. A built-in redundancy diode in each module allows for parallel connection and N+1
redundant operation. The system delivers a maximum of 3000W or 2000W with N+1 redundancy. Each module has a built-in fan which
provides sufficient airflow for operation at the specified temperature without de-rating. The fans draw air into the unit and the exhaust
exits at the rear of the unit. The cradle has no motherboard; the input and output cables are plugged directly into the module. This
contributes to the cost-effectiveness of this design. The modules can also be used as stand-alone units – mounting hardware is available.
Full electronic protection, generous design headroom and the use of components with established reliability results in a high
demonstrated MTBF confirmed by a track record in numerous applications. The system is manufactured at our plant under strict quality
control.
