Q50SN12072 DELTA 864W 1/4-Brick IBC Power Module | Isolated LLC Resonant

Shenzhen Mingjiada Electronics Co., Ltd. — Supplier of the Delta Q50SN12072 standard 1/4-brick isolated LLC resonant IBC power module, which is specifically designed for applications requiring 48V to 12V power conversion, such as high-density servers and AI computing clusters.

Product Overview:
The Delta Q50SN12072 is an industrial-standard 1/4-brick isolated LLC resonant IBC (Intermediate Bus Converter) power module, primarily intended for 48V two-stage power supply scenarios in cloud computing and high-density AI servers. The Q50SN12072 delivers excellent conversion efficiency and operational stability at high power densities, meeting the demanding requirements of 24/7, full-load operation in data centres.

Key Features and Technical Specifications of the Q50SN12072
Product Model: Q50SN12072RNDHQ
Industrial-standard packaging: Utilises a 1/4-brick package measuring 58.48 × 36.94 × 11.56 mm and weighing just 71 g, making it suitable for high-density layouts.
Wide input voltage range, high power output:
Input voltage: 38–60 V DC
Output voltage/current: 12 V / 72 A
Maximum output power: 864 W
High-efficiency topology: Utilises a hybrid LLC resonant + IBC isolated topology to achieve soft switching across the entire load range, effectively reducing switching losses and electromagnetic interference whilst enhancing conversion efficiency. Some data indicates that peak efficiency can reach 98.3 per cent.
Intelligent digital monitoring: Equipped with a comprehensive PMBus digital monitoring system, supporting parallel operation for capacity expansion to meet the demands of 24/7 uninterrupted operation in data centres.
Superior thermal design: The rear of the module is fitted with an aluminium alloy heat sink, with thermal compound filling the gap between the PCB and the heat sink to ensure reliable operation at high power levels.
