Electronic Measurements, Inc. 20-500-11-D Power Supply
 |
The Electronic Measurements, Inc. 20‑500‑11‑D is a laboratory‐grade variable DC power supply (EMS Series) that delivers a regulated voltage or current source with AC turn‑on/off capability and built‑in protection. Common failure modes for this model include output voltage drift due to aging regulator ICs, fuse or circuit breaker trips from overcurrent protection, overheating of the internal heat sink, and front‑panel meter misreadings caused by damaged potentiometers. First‑check diagnostics should verify that the unit powers on and that the AC input is within spec; inspect the main power fuse and any resettable fuses for continuity; then measure the output voltage with a calibrated multimeter while applying no load to confirm regulation and check for ripple or oscillation.[oss-gpt-20b] |
