Delta TDPS-750AB 750W Power Supply Unit (114-00065 REV:02F)

The Delta Electronics TDPS-750AB is a high-efficiency, carrier-grade switching power supply unit (PSU) designed for mission-critical networking and server infrastructure. This unit delivers a regulated 750W output, providing stable DC power to high-density switch chassis, routers, and storage arrays. It is engineered with a wide-range AC input (100–240V), ensuring global compatibility across various regional power grids. The TDPS-750AB features an 80 PLUS Platinum or equivalent efficiency rating, which minimizes energy loss and reduces the overall thermal footprint within the equipment rack, leading to improved hardware longevity and lower operational costs. The 114-00065 Revision 02F hardware spec includes an integrated intelligent cooling system with a variable-speed fan that adjusts based on real-time thermal load and ambient temperature. This proactive thermal management ensures optimal performance while minimizing acoustic noise. The PSU is equipped with multiple protection circuits, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP), safeguarding sensitive internal components from electrical anomalies. Its hot-swappable architecture allows for N+1 redundancy configurations, enabling the replacement or addition of power modules without interrupting system uptime or service delivery.

Built for high availability, the TDPS-750AB includes a standardized power-bus connector for seamless integration into backplane systems and a dedicated status LED indicator for immediate visual diagnostics (Power OK/Fault). The unit supports I2C/PMBus communication protocols, allowing system administrators to remotely monitor power consumption, voltage levels, and fan status through the host equipment's management interface. The ruggedized metal chassis is designed for standard 1U/2U form-factor slots, providing reliable grounding and electromagnetic interference (EMI) shielding compliant with international safety and emissions standards.
