XP Power - FLX1K3 – FLXPro Series: 1.3 kW AC-DC Power Supply with Intelligent and Flexible Capabilities

FLX1K3 from XP Power’s FLXPro Series — an intelligent, powerful, and flexible AC-DC power solution. With a compact size of only 254 × 89 × 41 mm, the FLX1K3 delivers up to 1.3 kW at high voltage (1.0 kW at low voltage) – achieving a power density of up to 23.2 W/in³. The SiC/GaN technology combined with a fully digital architecture allows the FLX1K3 to reach an efficiency of up to 93%, reducing cooling requirements, saving energy, and operational costs, with optimal performance and minimal heat dissipation.

With up to 4 output modules and voltage adjustments from 9 V to 66 V, ±10–40% adjustment, it supports parallel or series configurations as required, and can operate “live” without the need to power off. The FLX1K3 is equipped with a full digital interface, supporting PMBus via I²C, real-time control and monitoring; it features BlackBox Snapshot, data logging, and multi-layer security to reduce maintenance time and optimize system performance. The product meets 2 MOPP certification for medical applications, complies with IT standards, SEMI F47, with 4 kVAC input-output isolation, and supports operation in harsh environments from –20°C to +70°C.
