The Mean Well USA USP-500-24 is a 500-watt series AC DC converter designed for industrial and commercial applications. It features a 24V output voltage and a rated current of 21A, delivering up to 408W of power under normal conditions and 504W with forced air cooling.
This converter operates with a universal input voltage range of 90-264VAC and includes a built-in active Power Factor Correction (PFC) circuit, ensuring efficient power usage. Key features include adjustable output voltage, remote sensing, and ON/OFF control, along with an active DC OK signal.
The USP-500-24 has a chassis mount type and an open-frame construction, with dimensions of 254mm x 127mm x 41mm. It is designed for reliable operation within an ambient temperature range of -20°C to 70°C (with derating), and offers overload and over-voltage protection.
Safety standards include CB, CE, cURus, and TUV approvals, making it suitable for ITE (Commercial) applications. The unit also provides current sharing capabilities for 24V and 48V models.
The output voltage is 24V nominal.
The nominal output current is 21A.
The universal AC input range is 90 to 264VAC. DC input range is 127 to 370VDC.
The operating temperature range is -40°C to +85°C (derating applies above certain loads).
It is an open frame package with chassis mount.
Yes, it features an active PFC circuit. Typical power factor is 0.98 at 115VAC full load.
