Why Power Supplies Should Be Replaced Proactively
The EPRO A6371/00 converts incoming power to the regulated DC voltages your rack modules need. Inside, electrolytic capacitors smooth ripple and store energy. These capacitors age. For every 10°C increase in operating temperature, their life approximately halves. A power supply running in a 50°C cabinet on a factory floor will fail years before the same model in a 25°C control room.
We test every unit on a live EPRO chassis under load: all output rails verified, ripple within specification, protection circuits checked. 48-hour burn-in at 55°C to catch early-life failures. Printed test report. If you are ordering one replacement, order two — the spare will save you when the next one fails. 12-month warranty. Ships within 24 hours.
Compatible Parts — Same System
These modules share the same system family as the A6371/00. Commonly ordered together for complete rack builds or spare parts kits.
