Bel Power Solutions TET2200-12-086xD DC-DC Front-End Power Supplies

Bel Power Solutions TET2200-12-086xD DC-DC Front-End Power Supplies are 2200W DC-to-DC power supplies that convert -40VDC to -72VDC voltage into an insulated main output of +12VDC. The TET2200-12-086xD devices are ideal for powering intermediate bus architectures (IBA) in high-performance and reliable servers, routers, and network switches. The devices utilize fully digital control architectures for greater efficiency, control, and functionality. These DSP-controlled, fan-cooled modules are ideally suited for server integration with a matching airflow path. The fan speed adjusts automatically depending on power demand and supply temperature. This can be overridden through the I2C buses. 

Bel Power Solutions TET2200-12-086xD Power Supplies incorporate an interleaved forward converter topology with active clamp and synchronous rectification to reduce component stresses, providing increased system reliability and high efficiency. The series meets international safety standards and display the CE Mark for the European Low Voltage Directive (LVD).
