Information

Overview Manuals Common Applications Product Precautions

GE DS3820PSCC1D1B uses terminal strips and keyed internal connections to distribute its power-supply circuits. Its large clamped capacitor, transformers and heat sinks require discharge, polarity and thermal inspection during service.

Mark IV power-supply assembly
Two screw-type terminal strips
Ventilated metal housing with heat sinks
Transformers, capacitors, LEDs and adjustment components

The controlled system path is Mark IV cabinet source → DS3820PSCC1D1B conversion assembly → Filtered and thermally managed supply stages → Connected Mark IV control circuits. Verify each boundary against the installed project record.

Important Notice: Lock out the cabinet source and verify capacitor discharge before touching DS3820PSCC1D1B.

GE DS3820PSCC1D1B Technical Reference (PDF)GE DS3820PSCC1D1B Installation & Commissioning Guide (PDF)

The Technical Reference consolidates the verified data available for GE DS3820PSCC1D1B; the Installation & Commissioning Guide organizes controlled field preparation, checks and acceptance.

Mark IV supply replacement

Restores the exact DS3820PSCC1D1B power-supply position without changing cabinet architecture.

Power-path troubleshooting

Provides test boundaries at the terminal strips, connector interfaces and indicator points.

Preventive inspection

Supports checks of capacitor condition, heat-sink airflow, thermistors and connector integrity.

Controlled recommissioning

Allows staged input and downstream-circuit verification after an exact-identity replacement.

Apply these controls to GE DS3820PSCC1D1B before isolation, removal, reconnection, energization and release.

Lock out the cabinet source and verify capacitor discharge before touching DS3820PSCC1D1B.

Record every conductor on both terminal strips and every internal connector before disassembly.

Preserve polarity and connector orientation; do not rely on wire color alone.

Inspect the large clamped capacitor for leakage, swelling and secure mechanical retention.

Check heat sinks, ventilation openings and wire bundles for blocked airflow or heat damage.

Do not adjust potentiometers without the controlled calibration procedure and recorded as-found positions.

After repair, energize in a controlled sequence while monitoring indicators and downstream supply behavior.

Complete acceptance with cabinet-level protection, thermal and functional checks under the documented Mark IV operating condition.

Technical notes

GE DS3820PSCC1D1B is a housed Mark IV power-supply assembly with two terminal strips, transformers, capacitors, heat sinks and service indicators.
