iEi ACE-540A AC-DC AT Power Supply is a compact industrial power supply designed for legacy AT-based embedded systems, industrial computers, and OEM equipment that require dependable multi-rail DC output in a smaller power format. This 40W industrial AT power supply supports a dual input voltage range of 85~135VAC / 180~265VAC and provides multiple DC output rails including +5V, +12V, -5V, -12V, and +24V/1.7A, making it suitable for older embedded computer systems, low-power industrial control applications, automation equipment, and specialized legacy platforms.

The iEi ACE-540A is configured with traditional P8/P9 motherboard connectors along with FDD and 3x HDD connectors, making it a practical replacement option for legacy AT systems that still depend on older motherboard and peripheral power connections. With Power Factor Correction (PF) and an industrial design intended for continuous-duty operation, this unit is useful in maintaining older embedded systems where connector compatibility and output rail matching are important.
