Product Description
Allen-Bradley 80026-044-02 is an isolated gate driver power supply (IGDPS) used in MV SMC controller configurations that require continuous power for the gate-driver boards. The board accepts a nominal 50 V DC input and develops six isolated 20 V DC outputs.
Each output channel on the 80026-044-02 supplies an individual gate-driver circuit. Six green indicators show channel condition: an illuminated LED represents a healthy 20 V output, while an extinguished LED indicates that the corresponding output has fallen below 18 V.
The 80026-044-02 assembly is epoxy encapsulated and has no internal field adjustments or test points. If one of the six isolated outputs fails, the complete board is replaced rather than repaired at component level.

Six-Channel Isolated Output Structure
Independent channels
The board converts that input into six isolated 20 V DC outputs for the gate-driver circuits.
Whole-board boundary
The encapsulated construction makes the six-channel assembly the field-replacement unit.
LED & Test-Point Diagnostics
The 80026-044-02 uses one green indicator for each isolated output.
Healthy channel
An illuminated indicator corresponds to an output at the expected 20 V DC level.
Low channel
An indicator turns off when that channel drops below 18 V DC.
External measurement
Because the board has no internal test points or adjustments, checks are made at the defined external connections.
Frequently Asked Questions
What input should be present at 80026-044-02?
The expected input is 50 V DC, with the diagnostic check allowing 50 V DC ±8 V DC. Verify the feed before concluding that the encapsulated board has failed.
How many isolated outputs does 80026-044-02 provide?
It provides six isolated outputs. Each output is nominally 20 V DC and supplies a gate-driver circuit.
What does an unlit channel LED mean on 80026-044-02?
The corresponding output is below 18 V DC. Confirm the input and external connections, then evaluate the complete board as the replacement unit.
Can one failed output on 80026-044-02 be repaired in the field?
No internal field repair is defined for the epoxy-encapsulated board. A failure of one isolated output requires replacement of the complete board.
Does 80026-044-02 have adjustable output settings?
No. The board has no internal adjustments or internal test points.
Why is the exact 80026-044-02 catalog number retained?
Older official MV SMC material lists this exact catalog number, while later material also shows an -R service-part form. The ordered number should match the installed service record and quotation.
