Bel Power Solutions TET3200 AC-DC / HVDC Front-End Power Supply
Bel Power Solutions TET3200 AC-DC / HVDC Front-End Power Supply is a 3200W AC-DC power-factor-corrected (PFC) or DC-DC power supply. The unit converts standard AC mains power or high voltage DC bus voltages into a main output of 12VDC for powering intermediate bus architectures (IBA) in high-performance and reliability servers, routers, and network switches. The TET3200 has a universal input voltage range of 90VAC to 300VAC and a DC input range of 180VDC to 410VDC. The power supply is hot-plug capable and features I2C communication interface with Power Management Bus protocol for monitoring, control, and firmware update via bootloader. Bel Power Solutions TET3200 AC-DC / HVDC Front-End Power Supply meets international safety standards and displays the CE Mark for the European Low Voltage Directive (LVD).Features
