Mean Well SPV-300-12 Enclosed Switching Power Supply - 12V DC, 25A, 300W, Programmable Output
Mean Well SPV-300-12 Enclosed Switching Power Supply - 12V DC, 25A, 300W, Programmable Output
SPV-300-12
The Mean Well SPV-300-12 is a 300W enclosed switching power supply providing a regulated 12V DC output at 25A, with built-in active power factor correction. Its standout feature is a fully programmable output: the output voltage can be adjusted from 20% to 110% of nominal via a simple 1–5.5V DC external control signal, making it ideal for applications that need dynamic or fine-tuned voltage control.
With a universal full-range AC input of 88–264VAC (or 124–370VDC), it runs directly on Australian 240V mains. The slim 50mm-high enclosed case is cooled by free air convection — no fan — for silent, maintenance-free operation, and built-in remote ON-OFF control allows external switching of the output.
