Description
Product Overview
The CDMALL AC Motor Speed Controller is engineered for precise regulation of exhaust and inline fans used in hydroponic systems, grow rooms, workshops, and other indoor environments. Built around a robust AC brushed motor, the unit handles a maximum current of 15 A and a resistive load of up to 2000 W, while the inductive load limit is 1500 W, ensuring safe operation across a wide range of fan types. The controller features a 6‑foot grounded power cord that meets UL safety standards, a touch‑activated switch with three selectable speed settings (low, medium, high), and an independent fuse for overload and short‑circuit protection. Its compact dimensions—2.4 in × 1.5 in × 4.5 in—and brushed‑metal finish make it suitable for ceiling‑mount installations, while the ABS‑plastic insulated housing resists heat, deformation, and discoloration over prolonged use.

Usage
Designed for indoor applications, this controller excels in environments where airflow must be finely tuned. In hydroponic grow tents, users can lower fan speed during seedling stages to reduce stress, then increase it as plants mature to maintain optimal temperature and humidity. In workshops, the controller can moderate dust extraction fans, providing a quieter workspace while still delivering sufficient ventilation. The three‑speed touch interface allows quick adjustments without the need for tools, and the built‑in overload protection automatically shuts off power if the fan draws excessive current, protecting both the fan and the controller from damage. Because the unit operates on standard 120 V AC power, it integrates seamlessly with existing electrical systems in the United States.

FAQ
Can this controller be used with any AC fan?
Yes, the controller is compatible with most AC‑powered exhaust, inline, and ceiling fans that operate within a 120 V, 15 A rating and do not exceed a 1500 W inductive load.
How does the overload protection work?
The controller includes an independent fuse that trips when the current exceeds 15 A. Once the fault condition is cleared, the fuse can be replaced, and the controller will resume normal operation.
Is installation difficult?
Installation is straightforward: mount the controller on the ceiling using the provided hardware, connect the fan wires to the terminals, plug the 6‑foot cord into a standard 120 V outlet, and select the desired speed with the touch switch.
What warranty does CDMALL provide?
CDMALL offers a one‑year limited warranty covering manufacturing defects, along with access to technical support for troubleshooting and replacement parts.
Can the controller be used outdoors?
The unit is rated for indoor use only. For outdoor applications, a controller specifically rated for weather resistance should be selected.
