Fan speed controller for PC and AV gear

This Westinghouse 123A-4 unit converts 100-240V AC mains power into an adjustable 3-12V DC output rated at 36W. It is built for enthusiasts who want precise speed control over up to four 3-pin or 4-pin fans in computers, amplifiers, receivers or consoles.

Four-way PWM splitter cable included

The bundled splitter lets a single controller manage four fans at once, so all connected units ramp up or down together. A 5.5ft total cable reach — comprising 1.3ft AC input, 3ft DC output and 1.3ft splitter — gives flexible routing inside cases or equipment racks without extra extensions.

Metal housing with standard fan headers

The black metal enclosure weighs 0.168kg and measures 14.33in wide by 12.83in high by 9.06in deep. It accepts both 3-pin and 4-pin connectors, so builders can mix fan types without adapters, while the wide AC input range removes the need for a separate voltage selector when moving gear between regions.

Spørgsmål om denne vare

Does the 36W adapter or the 4-way PWM splitter cable need periodic replacement?

The unit is a sealed AC-DC adapter with no user-serviceable parts; the 4-way splitter cable and controller are designed to last the life of the installation.

What limits continuous operation when four fans draw the full 36W?

The 3-amp current ceiling on the 3-12V DC output is the first limit reached under sustained load.

How much heat and noise does the controller produce when running all day at 12V?

The metal-cased adapter runs silently with no fan of its own; warmth stays within normal levels for a 36W external power supply.
