Sharnoa Electronics R-741 Power Supply
 |
Sharnoa Electronics R‑741 is a 220 V AC rack‑mounted power supply designed to feed the 16‑bit R‑741 computer system. Common failure points in this class of industrial supplies include overheating transformers, failed rectifier diodes, and degraded capacitors that cause voltage ripple or shutdowns. Begin by verifying input mains voltage and measuring output rails with a calibrated multimeter; inspect for bulging electrolytics, burnt components, or loose connections; then review any system error logs for power‑related fault codes before proceeding to component replacement.[oss-gpt-20b] |
