California Instruments 2001L-1P-HV Controller
 |
California Instruments 2001L‑1P‑HV is a single‑phase, 2 kVA AC power supply with programmable output and GPIB interface. Common failure modes include tripped or failed internal fuses, degraded MOSFETs in the PWM stage, overheating of the heat sink, and loss of GPIB communication due to loose connectors. First‑check diagnostics: verify input voltage stability and correct range selection; inspect the power supply for blown fuses, burnt components, and ensure the heat sink is clean and properly attached; check GPIB cable continuity and connector pins for corrosion or looseness.[oss-gpt-20b] |
