System compatibility

502-031518-02 belongs to DANAHER MOTION Giddings & Lewis legacy CNC rack power family. Supplies power for CPU board, servo axis control cards, encoder boards and digital I/O modules. Widely used on heavy-duty boring mills, vertical turning centers and horizontal machining centers.

Function

502-031518-02 is rack mount switching power supply manufactured by DANAHER MOTION Giddings & Lewis. It accepts AC mains input and generates multiple regulated DC voltages to power all plug-in boards inside CNC rack. It continuously monitors output voltage and internal temperature. When fault occurs, power good signal triggers CNC system alarm to avoid damage to control cards. Internal fan dissipates heat under continuous full load operation.

Installation

Follow lockout/tagout safety procedure before installation. Cut off AC main power of CNC cabinet. Insert 502-031518-02 power module into vacant rack slot and lock retention bracket. Connect AC input cable following Giddings & Lewis hardware manual. Power on and measure each DC output voltage to verify specification compliance.

Interface

AC input terminal, gold-edge backplane connector, power status LED indicator for DANAHER MOTION 502-031518-02.

Feature

Original DANAHER MOTION 502-031518-02 CNC rack power supply,multi-channel regulated DC output,overvoltage/overcurrent/overtemperature protection,built-in cooling fan,gold finger rack plug-in design,UL & CE certified. This spare unit is used for legacy heavy CNC machine control rack power system maintenance and hardware replacement.

Diagnostic

No DC output: Check AC mains input, fuse integrity and fan operation. Output voltage drift: Inspect aging electrolytic capacitors and load condition of rack boards. Power alarm: Verify over-temperature trigger or overcurrent short circuit on backplane.
