MEAN WELL Switching Power Supply, SPV-300-12RS, 12V dc, 25A, 300W, 1 Output, 124 → 370 V dc, 88 → 264 V

The SPV-300 is a series of single output enclosed type power supply with programmable output voltage function. By adding 1∼5.5 Vdc external control signal the output voltage can be trimmed from 20% to 110% of the rated value, which increases the flexibility to end systems users and fulfils equipments which requires switching between different output voltages. This power supply is high frequency design and possesses efficiency up to 86.5%. The SPV-300 is cooled by a built in long life DC fan with on/off control. This switch mode power supply features short circuit, over voltage, overload and over temperature protection. Ideal applications for the SPV-300 include LCD panel burn in system, IC testing equipment, factory automation, mechanical and electrical industry, or any applications that often need to adjust the output voltage.
