Reference images and supplied-unit checks

This whole supplier composite is a different-unit reference showing SUNON base marking PSD1204PQB1-A, separate (2) and B3421.F.GN groups, DC12V 2.6W and Made in China wording. The catalogue joined punctuation and complete supplied option remain unverified as explained below.

The original composite includes label and pale-housing insets. The insets do not establish a single physical unit, supplied terminal keying, pinout or functions. Main-view lead terminations are not fully shown. Visible red, black, yellow and blue sections do not by themselves establish PWM or a supplied wiring specification.

The historical auxiliary marking is F8722E; the corresponding source small text is not fully transcribed. Confirm the actual current nameplate, harness, condition and fit before ordering. The printed 2.6W is power and is not an ampere rating.

Historical listing photographs are preserved in store records and backups.

Reference photograph source. Confirm the supplied unit before ordering.

PSD1204PQB1-A historical label groups and selection

The historical listing label shows the SUNON base marking PSD1204PQB1-A, with separate (2) and B3421.F.GN printed groups. The catalogue uses a joined identifier whose canonical punctuation has not been independently confirmed. These are historical label observations, not confirmation of the complete supplied option or an independent performance test.

Manufacturer on label SUNON
Historical printed label groups Base PSD1204PQB1-A; separate (2) and B3421.F.GN markings. Joined catalogue punctuation is unverified.
Nameplate voltage 12V DC

Which version should I match?

Compare the base PSD1204PQB1-A and the separately printed (2) and B3421.F.GN markings with the supplied unit. The catalogue joined identifier format is not independently confirmed. Confirm the complete supplied option, label, wiring and connector before ordering; shared base markings do not establish equal wiring or performance.

What else should I verify?

The label prints 2.6W as power. It is not an ampere rating; current and connector signal functions remain unconfirmed for this exact version.

Historical listing photographs are preserved in store records and backups. For a comparison, send a fan photo; for quantities, request a quote.
