Mean Well SP-500-24 Enclosed Switching Power Supply - 24V DC, 20A, 480W with PFC
Mean Well SP-500-24 Enclosed Switching Power Supply - 24V DC, 20A, 480W with PFC
SP-500-24
The Mean Well SP-500-24 is a 480W enclosed switching power supply delivering a regulated 24V DC output at 20A, with built-in active power factor correction (PF>0.95). Part of Mean Well's proven SP-500 series, it accepts a universal full-range AC input of 88–264VAC (or 124–370VDC), making it suitable for Australian 240V single-phase supply without any input selection.
Forced air cooling is handled by a built-in DC fan with intelligent fan ON-OFF control, keeping noise down under light loads. Remote ON-OFF control and remote sense functions are built in, allowing the supply to be switched externally and to compensate for voltage drop over long output cable runs — useful in control panels, machinery and distributed 24V DC systems.
