The Qualtek QPS-20-24 is a versatile 20-watt open-frame AC/DC power supply designed for various applications. It provides a stable 24V DC output at 840mA, suitable for projects requiring reliable power.
This power supply accepts a wide universal AC input voltage range from 90 to 264 VAC, making it adaptable for global use. Key electrical specifications include a typical efficiency of 79%, with line regulation of ±0.5% and load regulation of ±2.0%. It also features over-load, over-voltage, and short-circuit protections for enhanced safety and reliability.
The QPS-20-24 operates within a wide ambient temperature range of -20°C to 60°C and is cooled by free air convection. Its compact dimensions of 89.0mm x 51.0mm x 20.0mm make it suitable for integration into systems where space is a constraint. The open-frame construction allows for easy mounting and integration into custom chassis or enclosures.
The input voltage range is 90-264VAC at 47-63Hz, and it also accepts 127-370VDC.
The nominal output is 24VDC at 840mA, with a rated output power of 20W.
The QPS-20-24 is a chassis-mount converter measuring 89.0mm x 51.0mm x 20.0mm (3.50" x 2.01" x 0.79").
The operating temperature range is -20°C to 60°C with derating. Storage temperature range is -40°C to 85°C.
It includes over load protection at 105%-150% of rated output power, over voltage protection at 110%-140% of rated output voltage, and short circuit protection with auto recovery.
Typical efficiency is 79% at 230VAC input.
MTBF is greater than 200,000 hours at 25°C full load.
