Product Update Notice: DIN Rail Mounting Clip Material Upgrade

By Frank Chen/ Product Manager
Frank@meanwell.com

After deeply cultivating the Din Rail power supply market, MEAN WELL has managed to a foothold with millions of sales being made every year. Recently, we received some customers feedback on the plastic mounting clip. When being applied on the constantly vibrating devices (ex: railway transportation), the plastic mounting clip of Din Rail products may have long-term reliability doubt. The upgrade this time is to replace the plastic mounting clip material of 75~480W products with stainless steel components. Also, the die-casting material of SDR-960, TDR-960 series (960W) are replaced with stainless steel. For upgrade details and date, please refer to table 1.
 
The rail measurement of the upgrade version still follows the standard rail size, making them great alternatives. MEAN WELL fully takes in any relevant cost, making no adjustment on the pricing. Should there be any questions, please refer to the updated specification on the website or contact MEAN WELL sales representatives.
