Frequently Asked Questions

What is Delta Electronics BUB0512L-DA3L?
BUB0512L-DA3L is a Delta Electronics DC brushless centrifugal blower used in compatible electronic equipment and projector cooling assemblies. Complete-model suppliers identify 12 VDC, 0.12 A and a three-pin electrical connection.

Is BUB0512L-DA3L an axial fan or a centrifugal blower?
It is a centrifugal blower with a directional outlet. Its housing and airflow path differ from a conventional axial fan, so direct substitution requires checking the equipment ventilation geometry.

What is the rated voltage?
Multiple complete-model suppliers specify 12 VDC. The allowable operating voltage range was not independently established from a matching Delta approval specification.

What is the listed current?
The exact BUB0512L-DA3L model is commonly listed at 0.12 A. Confirm the current and electrical characteristics against the fan label and existing equipment requirements.

What is the electrical power?
Multiplying the listed 12 VDC by 0.12 A gives 1.44 W. This is a calculated reference, not an independently established manufacturer-rated typical or maximum input power.

What are the dimensions of BUB0512L-DA3L?
Multiple suppliers specify 50 x 50 x 25 mm. A separate field in one supplier listing states 50 x 50 x 20 mm, creating a dimensional discrepancy. Check the actual fan housing, outlet and mounting points before ordering.

How many wires and connector pins does the blower have?
Complete-model listings consistently identify three wires and a three-pin connector. One supplier describes an approximately 100 mm cable; another lists approximately 140 mm. Confirm the connector and required cable length.

Does the third wire provide tachometer feedback?
The available complete-model sales records do not establish the third wire's function. It may be associated with monitoring or another signal, but this should not be assumed without a matching connector diagram.

What are the fan speed and airflow specifications?
An exact-model Delta engineering specification confirming RPM and maximum airflow for BUB0512L-DA3L was not established. Values for other BUB series models should not be substituted.

What is the maximum static pressure and noise rating?
Neither maximum static pressure nor the acoustical noise rating was independently established for the exact -DA3L suffix. Request matching performance documentation if these values are necessary for cooling calculations.

Which BenQ projectors use BUB0512L-DA3L?
Spare-parts suppliers identify selected W1070, W1070+, W1075, W1080ST, W1080ST+, MH680, MW603, MX602, TH680 and TH681 series projectors. The fan is also associated with BenQ part number 2C.J7L04.001. Verify the exact projector revision and installed fan before replacement.

What should be checked before ordering Delta BUB0512L-DA3L?
Confirm the complete BUB0512L-DA3L marking, 12 VDC supply, 0.12 A listed current, actual housing thickness, mounting arrangement, outlet direction, three-pin connector, wire sequence, cable length, projector part number and compatibility with the original cooling assembly.
