The Mean Well PS-65-24 is a 65W single-output switching power supply delivering stable 24V DC at 2.7A for industrial and electronic equipment. This compact aluminum-housed unit accepts universal AC input (85-264VAC, 47-63Hz) or DC input (120-370VDC), making it suitable for global deployment. Built-in overload protection with constant current limiting and auto-recovery safeguards against faults at 105%-150% rated power. Over-voltage protection clamps output at 27.6V-32.3V with automatic recovery. The supply achieves low ripple and noise performance at ≤150mVp-p and includes comprehensive isolation withstand testing (3kVAC input-to-output, 1.5kVAC input-to-ground, 0.5kVAC output-to-ground).
