Delta Technologies 910-4800 battery charger

The Delta-Q QuiQ 910‑4800 is a high‑frequency, off‑board battery charger designed for 48 V lead‑acid packs (often used in forklifts and golf carts). Common failures include the internal power MOSFETs or rectifier bridge overheating due to dust ingress, a defective DC‑DC regulator causing voltage ripple, or a failed temperature sensor that triggers an overheat shutdown. First‑check diagnostics: verify the input AC supply is within spec (120 V/230 V ±10%), inspect the charger enclosure for moisture or debris and ensure ventilation; then read any fault codes from the built‑in LCD or diagnostic port, and finally measure output voltage and current under load to confirm proper charging curves.[oss-gpt-20b] Post Comment
