System compatibility

0-57026 belongs to RELIANCE MaxPak series auxiliary power supply board.

Designed for Reliance legacy MaxPak DC drive rack.

Supply stable low voltage power for ACCA 0-52837,IRFA 0-52850,VCTC 0-52854,CVCB 0-52855 and VTGA 0-52876.

Used to convert AC input into multiple DC control voltages for drive control boards.

Commonly used for old drive equipment maintenance and spare replacement.

Function

0-57026 is auxiliary power supply card for RELIANCE MaxPak DC drive.

Convert AC auxiliary input to multiple DC regulated voltages for all control PCB cards.

Provide isolated ±15V,+5V working power for analog amplifier and logic circuits.

Built-in over-current and short-circuit protection for power output channels.

Monitor output voltage status and send fault signal when voltage deviation occurs.

Stabilize control power to prevent drive malfunction caused by power fluctuation.

Installation

Power off the whole drive cabinet and cut main power supply.

Insert 0-57026 board into MaxPak designated slot.

Fasten front panel fixing screws.

Connect edge connector and AC input terminals.

Check wiring insulation and terminal tightness.

Power on system,measure each DC output voltage.

Verify all control boards can work normally after power supply startup.

Interface

MaxPak edge connector,AC input terminal strip,multi-channel DC output terminals,power status LED indicators.

Feature

RELIANCE 0-57026,MaxPak auxiliary power supply PCB assembly.

Multi-channel isolated regulated DC output for analog control boards.

Hardware short-circuit protection for each output rail.

Onboard fuse for each power channel to protect downstream control cards.

Clear terminal marking for safe measurement and troubleshooting.

Discontinued obsolete board,supply only for old drive equipment spare replacement.

Suitable for metallurgy,paper-making heavy-duty MaxPak DC drive renovation.

Diagnostic

All control boards no power:AC input missing or primary fuse blown;

Individual channel voltage abnormal:output regulator component aging;

Power board repeatedly trips:short circuit on downstream control board;

LED indicator off:no AC input or internal circuit damage.
