DVE DSQ-142L power supply

The DVE DSQ‑142L is a 12 V/15 A industrial switching power supply commonly installed in HP/Dell KVM switches and CCTV camera enclosures. Typical failure modes include degraded or failed electrolytic capacitors (notably C12), burnt-out MOSFETs, or damaged output rectifier diodes that manifest as no output voltage or overheating. First‑check diagnostics: verify input AC to the PSU housing, measure the 12 V DC rail with a multimeter while monitoring for ripple spikes; inspect the board for bulging or cracked capacitors and solder joint integrity; review any diagnostic LEDs or error codes on the host device that may point to PSU faults.[oss-gpt-20b] Post Comment
