Power Supplies Do Not Last Forever
Electrolytic capacitors in switch-mode power supplies degrade with time and temperature. The Honeywell 51308105-400 should be considered a consumable with a 5-7 year service life in typical industrial environments — shorter if the rack runs hot. We test every unit on a live chassis under load: voltage regulation, ripple, efficiency, protection circuits. 48-hour burn-in at 55°C catches the early failures. Printed test report included.
