Tripp-Lite PR-30 DC power supply Repair Service

Professional diagnostic and board-level repair service for this Tripp-Lite PR-30 DC power supply.

The Tripp‑Lite PR‑30 is a 30 A, 13.8 V DC power supply that converts 120 VAC to a precision‑regulated low‑voltage rail, commonly used in radio transmitters, test benches and industrial control panels. Typical failure modes include blown internal fuses or crowbar protection tripping, degraded electrolytic capacitors causing output voltage drift, and overheating of the heat sink due to inadequate ventilation or a failing regulator IC. First‑check diagnostics should verify that the AC input is within spec (120 VAC ±5 %) and that the unit’s thermal case is clear; then measure the 13.8 V output with a calibrated meter while monitoring for ripple or spikes, inspect for scorch marks or bulging capacitors, and test the internal fuse and crowbar circuit continuity.
