Electronic Measurements, Inc. ESS 55-310-2-D 00481279 Power Supply
 |
The Electronic Measurements, Inc. ESS 55‑310‑2‑D is a high‑power programmable DC power supply (10 kW class) that delivers constant voltage or constant current with pulse‑by‑pulse current limiting and built‑in over‑voltage protection for the load. Common failure modes in this series include blown internal fuses, degraded output capacitors causing voltage ripple or drift, failure of the PWM control IC leading to erratic regulation, and overheating of the power MOSFETs due to inadequate cooling or fan failure. First‑check diagnostics: verify that the unit receives proper mains input and that the main fuse is intact; inspect the output capacitor bank for bulging or leakage and measure output voltage/current under load against spec; check the status LEDs and any error codes displayed, then confirm that the cooling fan is operating and airflow is unobstructed.[oss-gpt-20b] |
