The GAPTEC Electronic 45ACO_12S3 is a 45-watt AC-DC converter from the 45ACO_3 series, designed for high power density in a compact 3x2 inch form factor. It accepts a universal input voltage range of 85-264 VAC or 100-370 VDC, making it suitable for global applications. This open-frame converter provides a regulated single output of 12VDC with a maximum current of 3.75A.
Key electrical specifications include an efficiency of 84%, line regulation of ±0.5%, and load regulation of ±1%. It offers 3000 VAC isolation between input and output and includes over-voltage and over-current protection features. The operating ambient temperature range is -25°C to +70°C, with derating applied at temperature extremes.
Designed for ITE (Commercial) applications, the 45ACO_12S3 is suitable for surface mounting. Its dimensions are 76.2mm x 50.8mm x 30.0mm. The converter meets safety standards such as IEC62368-1 and is approved by cURus and UL agencies. It is also compliant with CISPR32/EN55032 Class B for EMI performance.
The AC input range is 85-264 VAC, and the DC input range is 100-370 VDC.
The output voltage is 12 VDC, and the maximum output current is 3.75 A.
The operating temperature range is -25°C to 70°C (with derating).
The package is a 7-SMD Module with 6 leads, surface mount.
