The Triad Magnetics ABU125-050 is a single-output AC/DC power supply designed for industrial and telecommunications applications requiring high reliability. It delivers 70W of power with a 5VDC output voltage, adjustable from 4.75V to 5.25V.
Key electrical specifications include a wide input voltage range of 90-264VAC, a typical efficiency of 79.0% at full load, and Power Factor Correction (PFC) greater than 0.95 at 230VAC. The unit offers robust protection features such as over-current protection (22.0-30.0A) and over-voltage protection (5.75-6.75VDC).
Designed for chassis mounting, this open-frame power supply measures 127.0mm x 76.2mm x 26.6mm. It operates within a temperature range of -20°C to 50°C at full load and can be cooled by natural convection or a fan. The ABU125-050 complies with European EMC standards (EN55022 Class B, EN61000-3-2) and Low Voltage directives, with safety approvals including UL 60950-1.
The input voltage range is 90-264VAC (also accepts 127-373VDC).
Output voltage is 5VDC ±2% (adjustable 4.75-5.25V) with output current up to 14A under convection cooling, providing 70W.
The converter measures 127.0mm x 76.2mm x 26.6mm and weighs 300g. It is chassis mountable.
Full load operation from -20°C to 50°C, with derating up to 70°C.
It is approved to UL 60950-1 and carries CB, CE, TUV, UR markings.
Over current protection (hiccup mode, 22-30A) and over voltage protection (5.75-6.75VDC) are built in.
Typical efficiency is 79% at 230VAC full load, with an additional 87% figure from existing data.
