The TET4000-48-069RAH, a 4,000-W power supply, was designed to provide efficient power conversion for data centers being built to Open Compute Project (OCP), Open Data Center Committee (ODCC), or Central Office Re-architected as a Datacenter (CORD) standards. The adoption of 48 V for data center power distribution is accelerating as it can improve PUE, lower total cost of ownership (TCO), and boost computing density and rack utilization. The TET4000-48-069RAH is designed to provide peak efficiency over 97.5%, classified as Titanium level, the highest efficiency classification for power supplies. Housed in a compact form factor, it’s programmable from 42 to 58 VDC with power-factor correction (PFC). The unit also allows for a DC input voltage range of 240 to 380 VDC, delivers power density of 44 W per cubic inch, and incorporates soft-switching resonant techniques in conjunction with synchronous rectification, providing increased system reliability and very high efficiency. Other features include an always-on +12-V, 60-W standby output and a CAN communication interface for monitoring, control, and firmware updates via a bootloader. This power supply meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD), with patents pending.
