Variable Speed Fan Control KB Electronics KBWC-15K Wall Mount 5A 120V

Description

Product Overview

The KB Electronics KBWC-15K Variable Speed Fan Control is engineered for demanding industrial environments where precise airflow control is essential. This wall‑mount controller delivers a continuous current rating of 5 A at 120 V, making it suitable for a wide range of shaded pole and permanent split capacitor (PSC) motors. Its compact dimensions—4.5 × 2.8 × 2.3 inches—and lightweight design (3.2 oz) allow for easy installation in tight spaces. The unit features an adjustable minimum voltage calibration, enabling users to fine‑tune fan start‑up characteristics and maintain consistent speed under varying load conditions. Constructed from high‑temperature resistant polymer housing, the controller offers durability against dust, moisture, and mechanical impact, ensuring long‑term reliability in factories, warehouses, and large‑scale HVAC systems.

Usage

Designed for industrial and scientific applications, the KBWC-15K excels in environments where continuous ventilation is required. Typical installations include manufacturing plants, cold‑storage facilities, data‑center cooling racks, and large‑area exhaust systems. The wall‑mount form factor allows the controller to be positioned near the motor cabinet, reducing wiring length and simplifying maintenance. Users can calibrate the minimum voltage to match specific motor characteristics, ensuring smooth start‑up and preventing motor stall during power fluctuations. The controller’s universal compatibility with both shaded pole and PSC motors makes it a versatile choice for retrofitting existing fan systems or integrating into new designs.
