Description
The SUNON UB5U3-500 is an ultra-compact 3-wire MagLev mini DC blower engineered for high-density electronic applications requiring real-time speed monitoring and closed-loop thermal control. Featuring a low-profile 30 x 30 x 3 mm (1.18 x 1.18 x 0.12 inches) footprint and weighing 2.4 g (0.005 lbs), this unit is built with flame-retardant Liquid Crystal Polymer (LCP) components rated UL 94V-0. Operating on a 5 VDC nominal supply with SUNON’s Vapo bearing system, it incorporates a third yellow signal lead wire alongside IP55 dust and moisture sealing.
Key Features
- Integrated 3-wire harness with UL10064, 32 AWG lead wires (+Red, -Black, Yellow 3rd Wire) for real-time motor speed telemetry.
- Micro-scale 30 x 30 x 3 mm (1.18 x 1.18 x 0.12 inches) Liquid Crystal Polymer (LCP) structure rated UL 94V-0 for high flame resistance.
- Magnetic levitation (MagLev) drive mechanism with Vapo bearing architecture guarantees stable 9500 RPM counter-clockwise rotation.
- Delivers a maximum static pressure of 88.18 Pa (0.354 inH2O) alongside an air delivery rate of 18.0 l/min (0.635 CFM).
- IP55 environmental protection rating combined with automatic restart locked rotor shutdown and reverse polarity protection.

Frequently Asked Questions & Technical Support
What is the function of the 3rd yellow wire on the SUNON UB5U3-500?
The 3rd yellow wire (UL10064, 32 AWG) on the SUNON UB5U3-500 serves as a signal lead for speed monitoring and tachometer telemetry. This allows system microcontrollers to track motor rotation speeds in real time and trigger system alerts if airflow drops.
How does the 3-wire UB5U3-500 differ from 2-wire models like the UB5U3-700?
While both units feature identical 30 x 30 x 3 mm (1.18 x 1.18 x 0.12 inches) dimensions, 5 VDC operation, 9500 RPM speed, 18.0 l/min (0.635 CFM) airflow, 88.18 Pa static pressure, and IP55 protection, the UB5U3-500 includes an extra yellow signal lead for speed feedback, whereas standard 2-wire models provide power leads (+RED, -BLACK) only.
What structural materials and protection ratings are used in the UB5U3-500?
The SUNON UB5U3-500 is constructed with UL 94V-0 rated thermoplastic LCP for both housing and impeller. It carries a certified IP55 ingress protection rating against dust and moisture, supported by internal locked-rotor auto-restart and polarity protection.
How can procurement engineers obtain 3D CAD files or submit a bulk RFQ for the UB5U3-500?
Procurement engineers can request STEP/IGES 3D CAD models, signal circuit schematics, or submit a bulk RFQ by contacting our technical sales team with the exact UB5U3-500 part number and expected order volume.
