Product Description

The MOX12/4U-P3509B (also referenced as MOX12-P3509B, part number 80026-173-23 / 80026-173-23-R) is a switching power supply / DC/DC converter

module intended for industrial automation or control systems (often associated with Allen-Bradley / Rockwell Automation spare parts, but the

underlying manufacturer is Absopulse).this is a multi-output industrial switching power supply module, designed to supply

 a variety of DC voltages (both positive and negative) for a control system rack or module

 environment, rather than a simple single-rail power supply.

Q1: What voltages does this power supply provide?
A1: According to one detailed listing, the MOX12/4U-P3509B provides multiple output rails: ±5 VDC (10 A), ±15 VDC (1 A), +12 VDC (1 A), +24 VDC (2 A),

±24 VDC (1 A), +15 VDC (1 A).  Another listing shows simplified outputs: 5 V, -15 V, +15 V, +12 V, +24 V, -24 V. 

If you have a specific rails-requirement, you should check the exact version/label on

your module since there may be variants.

Q2: What input voltages are supported?
A2: There is some variation: one listing shows 42-258 VDC input up to 8 A. Another shows 115 VAC (47-63 Hz) with ~97-132 VAC

operating range, with 230 VAC and other options available.  You’ll need to check the label on your unit

(or consult the manufacturer) to be sure which input version you have.

Q3: Is this genuine Allen-Bradley or Absopulse?
A3: The part is often listed as an Allen-Bradley part number (80026-173-23) and is compatible with Allen-Bradley/ Rockwell

Automation systems, but the original manufacturer appears to be Absopulse (or the module is built by Absopulse

and rebranded/used by Allen-Bradley). Many listings reference Absopulse as the brand for MOX12-P3509B.

 So yes — it is used in the Allen-Bradley ecosystem, but is likely

 a third-party or OEM module in that sense.

Q4: Can I replace it with a newer Allen-Bradley module?

A4: Possibly — but you must check that the replacement has exactly the same input and output voltages, current

 ratings, dimensions, mounting interface, connector pin-out, and thermal characteristics. Given the multi-rail

and specific form factor nature of this module, a direct “drop-in” replacement may not exist

 unless listed by Rockwell/Allen-Bradley as such.

 Also check revision (“-R”) suffix.
