This article covers JD12038AC 220V 120MM 220V 0.14A 12038 ボール軸流ファン。. ## Overview
The JD12038AC is a 120mm x 120mm x 38mm ball-bearing axial fan designed for industrial and commercial cooling applications. It operates directly on 220-240V AC power with a low power consumption of just 1W and a current draw of 0.10/0.14A. Unlike standard PC case fans that require 12V DC, this fan plugs straight into an AC mains outlet, making it ideal for equipment racks, power supplies, and control cabinets. The copper motor construction ensures efficient heat dissipation and long-term reliability. ## Key Features
120x120x38mm frame with ball bearings – Ball bearings offer superior durability compared to sleeve bearings, especially in high-temperature or continuous-operation environments. Rated for 220-240V AC, 0.10/0.14A, 1W power consumption – No external power adapter needed; direct connection to AC mains. Copper motor winding – Copper provides excellent thermal conductivity, helping to keep the motor cool during extended use. Factory-tested before shipment – Each unit is verified to be in working condition, reducing the risk of DOA (dead on arrival). ## Connectivity & Compatibility
This fan is designed for AC 220-240V direct connection only. It is NOT compatible with standard PC motherboard fan headers (which use 12V DC). Typical use cases include industrial machinery, server racks, audio amplifier racks, and DIY ventilation projects where AC power is readily available. The fan comes with bare lead wires; users may need to add their own connectors or terminals for installation. ## Product Info
The JD12038AC has been available on for some time, with a price typically around ¥1,000 (subject to change). The manufacturer is listed as SA12038B2H, and the UPC is 755361303900. The package includes only the fan unit itself – no mounting screws, brackets, or manual are included. Always verify the dimensions (120x120x38mm) and voltage (220-240V) before purchasing. ## Best Use Cases
This fan is best suited for replacing or adding cooling in industrial equipment, control panels, server racks, or DIY AC-powered ventilation systems. It is also useful for hobbyists building custom exhaust fans for workshops or garages. However, it is NOT intended for standard PC cases – if you need a case fan, look for a 12V DC model instead.
