Description
ABB SAMC 11 POW is a power-supply card for legacy drive-control electronics and pulse-amplifier circuits.

It generates stabilized control voltages together with the documented 25 V, 35 kHz firing supply and monitors auxiliary and DC-link conditions.

Replacement requires confirmation of TBU code 57171847, part number 104750, the host drive, connector arrangement and input supply.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What should be checked if ABB SAMC 11 POW does not energize the control electronics after installation?
Verify the 30–55 V DC input, polarity, connector seating, rack position and upstream protection, then check for a short or excessive load on the stabilized control-voltage outputs.
What should be checked before installing ABB SAMC 11 POW in a legacy drive or braking unit?
Verify the 30–55 V DC input, connector and rack position, control-electronics load and firing-pulse supply requirements of the installed unit.
What fault indications depend on ABB SAMC 11 POW?
The official circuit supervises auxiliary voltage through FLTA, control-card presence through FLTX and intermediate DC-link undervoltage through UCM1.
Why can ABB SAMC 11 POW appear powered while firing circuits still fail?
The stabilized logic rails can be present while the separate 25 V, 35 kHz supply to the pulse amplifiers is missing or loaded incorrectly.
What happens to fault memory if ABB SAMC 11 POW loses auxiliary power?
The documented backup battery maintains fault memory and the LED for about ten hours; battery condition must still be verified during service.
What should be reviewed before reconnecting option cards to ABB SAMC 11 POW?
Confirm the option-card type, connector assignment and total auxiliary load against the original configuration; the card provides capacity for documented options but does not make every additional load compatible.
What should be tested after replacing ABB SAMC 11 POW?
Test the stabilized rails, auxiliary-voltage supervision, DC-link undervoltage signal, firing-pulse supply and any option-card loads before return to service.
