Rapid Power Restoration: Back online same day.
Power-on failures range from dead standby to clicking relays. Swollen capacitors block rails; MOSFET shorts draw excess current. Prologic technicians load-test PSUs with variacs, graphing voltage curves. Nairobi brownouts bake electrolytic caps prematurely.
Feedback loops fail, causing overvoltage shutdowns.
Failure Patterns
No LED: primary fuse blown. Pulsing light: protection mode. Click-loop: shorted load.
Warm standby but no main power: relay coil open.
Diagnostic Approach
ESR meters test cap health. Curve tracers profile transistors. Ripple scopes reveal feedback issues.
Inrush limiters isolate cold-start faults.
Comprehensive Fixes
Capacitor sonic-welding prevents microphonics. Optocoupler swaps restore feedback. Snubber networks tame switching noise.
PFC boost diodes replaced.
Advanced Gear
Hipot testers verify isolation. Power analyzers measure PF. Thermal chambers accelerate aging tests.
Client Advantages
Stable 5-year power delivery. Silent operation. Energy-efficient post-repair.
