AC 230 V case fan for industrial enclosures

This Vszerda 4715MS-23T-B50 is a 120×120×38 mm axial fan powered directly from 230 V AC mains at 50/60 Hz. It suits builders and maintainers who need a drop-in replacement for NMB original parts in server racks, telecom cabinets or industrial chassis where DC power is not available. The black frame and 2-pin BTH connector match the legacy mounting pattern.

2-pin BTH connector and fixed-speed operation

The bundled 2-pin BTH connector provides a simple polarity-free hookup to existing wiring harnesses without adapters. No PWM or voltage-control circuitry is present, so the fan runs at a constant 2800 rpm whenever mains power is applied, delivering 45 dB of acoustic output. This fixed-speed behaviour means no software configuration or motherboard header is required.

15/14 W power draw and 2800 rpm airflow headroom

At 15 W on 50 Hz and 14 W on 60 Hz the unit moves enough air for typical 12038 form-factor cooling slots in power supplies, UPS units or dense networking gear. It will not suit builds that demand variable-speed quieting, PWM fan curves or lower-than-45 dB noise floors. Buyers needing speed control, DC voltage input or a different connector pitch should look elsewhere.

Questions about this item

How often will the 2-pin BTH connector or sleeve bearings need servicing on the 4715MS-23T-B50?

The 2-pin BTH connector is a simple push-fit and has no moving parts; the fan uses sleeve bearings that typically run for years before any lubrication or replacement is considered.

What stops the 4715MS-23T-B50 from spinning faster during continuous 230 V AC operation?

The motor is wound for 2800 rpm at 50/60 Hz, so line frequency and the 15/14 W power ceiling set the hard speed limit under sustained load.

How much heat and noise does the 4715MS-23T-B50 add when running all day at 230 V AC?

It draws 15 W at 50 Hz or 14 W at 60 Hz and produces 45 dB of airflow noise; the metal frame conducts some warmth but stays safe to touch.
