With its ETL and CSA certifications, this driver ensures safety and reliability, while its auto-reset circuit breakers and compatibility with various wall dimmer switches make it a versatile choice for any lighting setup. ## Description This Class 2 Compliant and energy efficient dimmable led driver has the highest efficiency with no wattage derating 100% load. Made in the USA. These drivers will do more than power your LEDs they will make your design dreams into realities. This 40 watt dimmable power supply is certified for its efficiency and durability: ETL, CSA Listed, UL Standard 120 V A/C input. 12V DC OUTPUT Magnitude’s AR-Series (auto-reset) of dimmable magnetic DC drivers are built especially for LED systems. They provide the following benefits: Compatibility – There are no minimum load requirements when used with a dimmer. The drivers cause no flicker or any of the other side effects that can result from a lack of synchronization between voltage mode drivers and PWM low voltage drivers in the light fitting. Perfect Dimming – Fully compatible with low voltage dimmers, in contrast to voltage mode drivers that balance the voltage in the system and prevent the dimmer from working. Lower Power Consumption – Bring about an improvement in efficiency of 15%, due to the avoidance of unnecessary double conversion in the circuitry. Compatible with the following low voltage magnetic analog dimmers: Lutron Ariadni Dimmer AYLV-603P AYLV-600P Lutron Vareo Dimmer V-1000 V-600-S VETS-1000-CSA VETS-R VETS-1000-SL-S Lutron Nova Dimmer NTLV-1000 NTLV-1500-S NTLV-1503P NTLV-603P NTLV-603P-CSA NTLV-1003P-S NT-3PS-CSA NT-4PS-CSA NT-1PS-CSA Lutron Ceana Dimmer CNLV-603P Lutron Diva Dimmer DVLV-103P DVSCLV-603P DVLV-103P-S DVLV-603PH-S DVLV-600P DVSCLV-600P DVLV-10PH-S SC-3PS SC-1PS SC-4PSNL Lutron Glyder Dimmer GLV-600 Lutron Lyneo Dimmer LXLV-103PL LXLV-600PL Lutron Nova T Dimmer NTLV-1500 NTLV-600 Lutron Skylark Dimmer SLV-603P SLV-600P Leviton Illumatech Dimmer IPM06-1LZ Leviton Mural Dimmer MDM06-1LI MDM10-1LI Leviton SureSlide Dimmer 6613-PLT 6613-PLA Leviton ToggleTouch Dimmer TGM10-1LI TGM10-1LT Leviton Vizia Dimmer VPM06-1LZ ## Features - No RFI Issues – Operate at a perfect 60Hz sinus wave, therefore they produce no radio frequency interference whatsoever. - Auto-Reset Circuit Breakers – The AR-series offers breakers on both the input and the output. - 12V 40 Watt Magnetic Dimmable LED Driver - ETL Listed, CSA Listed, UL Standard 5085-1 - Compatible with Many Wall Dimmer Switches (make sure you consult compatibilty list) ## Images ![12V Dimmable LED Driver - For Constant Voltage Products Only - Min/Max LED Wattage 40W - Driver Input 120V - Magnitude M40L12DC-AR - Image 1](https://m.media-amazon.com/images/I/51oArqbRTgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Between the driver and dimmer, you're talking a lot of money just to dim the LED's. *by T***C on Reviewed in the United States πŸ‡ΊπŸ‡Έ on March 27, 2018* The unit seems to work as expected. Is it the Lutron dimmer or the driver transformer or the combination of the LED's that won't allow the LED's to dim completely out without turning off the switch? I don't know. I suppose the driver works because you can dim the LED's as promised. ### ⭐⭐⭐⭐⭐ Five Stars *by R***E on Reviewed in the United States πŸ‡ΊπŸ‡Έ on September 5, 2016* excellent ### ⭐⭐⭐⭐⭐ Very good *by M***1 on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 16, 2015* High quality metal, well made. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/14369218-12v-dimmable-led-driver-for-constant-voltage-products-only-min](https://www.desertcart.co.uk/products/14369218-12v-dimmable-led-driver-for-constant-voltage-products-only-min) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
