Prescolite Controls series 7-12 light dimmer Control Panel
 |
Prescolite Controls Series 7‑12 is a 12‑channel analog/digital lighting dimming controller used in industrial and commercial applications. Common failure modes for this class include burned or tripped MOSFETs on the output stage, failed opto‑isolators in the demultiplexer board, and degraded capacitors on the power supply section; these often present as channel dropouts or erratic dimming behavior. First‑check diagnostics: verify the 12 V/24 V input voltage and ensure the main power supply is within spec; inspect the output MOSFETs and opto‑isolators for visible damage or overheating; and review any diagnostic LEDs or error codes on the panel, correlating them with the channel map.[oss-gpt-20b] |
