One of the more serious problems in the residential and light commercial lighting industries is frequent incompatibility between LED lighting and dimmers. One company has a new solution specifically for low-voltage, 24VDC lighting (typically linear).
NSL introduced Dim Drive, an all‑in‑one low‑voltage LED lighting solution that integrates a 24VDC constant‑voltage LED driver and a full‑range dimmer into a single, wallbox–mounted device designed for electricians, distributors, designers, and homeowners. Dim Drive is a simple, reliable alternative to traditional separate drivers and dimmers, with ease of installation, broad applications, and flicker‑free performance for 24V LED systems.
Dim Drive exists to eliminate compatibility problems and complexity in low‑voltage LED installations by combining the driver and dimmer into one product. Its form factor mimics familiar wall dimmers (similar in appearance to Lutron Diva), so installers and end users can treat it like a standard control while benefiting from integrated power conversion. NSL stresses its “two‑in‑one convenience,” arguing this reduces parts, streamlines purchasing, and simplifies troubleshooting in the field.
Dim Drive is designed to fit standard wall boxes and is suitable for multi‑gang configurations, making it practical for both new construction and retrofit projects. The unit allows easy “trimming” (adjusting high‑ and low‑end light levels) and features zero load derating, meaning performance is maintained even in multi‑gang setups without complicated de‑rating calculations. Three‑way switching support lets users control the same lighting load from multiple locations, further aligning with conventional residential and light commercial wiring practices.
In terms of performance, Dim Drive provides full‑range, flicker‑free dimming using quiet 16 kHz PWM (pulse‑width modulation), providing smooth control from 0.3% up to 100% light output. Built‑in protection features include short‑circuit, overload, and over‑temperature safeguards with automatic recovery, aiming to enhance reliability and reduce service calls. NSL also claims better value than competing products such as Switch‑Ex, noting both lower cost and what it describes as an improved design.
In terms of applications, Dim Drive is a potential solution for nearly any 24V LED lighting project. Suggested uses range from under‑cabinet kitchen lighting and cove or ceiling perimeter lighting to toe‑kick and stair accents, mirror and TV backlighting, and lighting for closets, wardrobes, and display cases. NSL specifically recommends pairing Dim Drive with its own ST and SL Series LED tape, Neon Flex, Hard Strip, or 24V EStrip products for consistent performance and streamlined system design.
Dim Drive accepts 120 VAC input and delivers 24 VDC output, with available 60 W and 100 W models. It offers 91% efficiency at full load and a power factor greater than 0.99, indicating strong electrical performance and reduced waste. The unit operates in temperatures from –40 °C to +60 °C and is rated for dry and damp locations, broadening its use across varied environments. Certifications include UL, cUL, FCC, Class P, SELV, RoHS, and REACH, which collectively signal compliance with safety, electromagnetic, and environmental standards.
A “Built for Installers” section reinforces that the product is optimized for field use. Dim Drive mounts directly into a standard switch box and incorporates an isolation barrier that safely separates high‑ and low‑voltage sections, important in multi‑gang walls where multiple circuits may coexist. A rotatable partition and clear wiring diagram are mentioned as features that help achieve quick, code‑compliant installations and reduce confusion during wiring.
Dim Drive is a simplest, cost‑effective way to power and dim 24V LED lighting, making it a smart choice for modern low‑voltage projects. NSL announced a forthcoming product, Dim Drive+, scheduled for release soon, which will add CCT tunability for dynamic white‑light control while retaining the same compact, installer‑friendly design.
