Neon Flex Driver Sizing and Power Planning
How to size drivers for neon flex runs — voltage drop, max length per feed, loading factor, and DMX panel inrush notes.
Neon Flex Driver Sizing
**Quick Answer:** Size neon flex drivers to the total wattage of each feed at the correct voltage (12V or 24V), load to about 80% of driver rated capacity, respect max run length per feed to limit voltage drop, and plan separate feeds or dual injection for long facade segments.
Calculate Load
1. Obtain W/m from datasheet for your color and IP SKU 2. Multiply by installed length per feed 3. Add 10–15% headroom for supply tolerance
Voltage & Run Length
24V neon flex generally allows longer feeds than 12V before visible dimming at the far end. Request factory run-length chart with wire gauge from driver to first entry point.
Loading Rule
Continuous operation at 100% driver rating reduces life — target **80% load** for thermal margin.
Multiple Feeds & Inrush
Facade DMX projects may energize many feeds simultaneously — coordinate inrush with electrical engineer and controls vendor.
Q: One driver per color channel on RGB?
RGB/RGBW systems need channel-appropriate power supplies or integrated control gear — document in controls spec.
Q: Can Mihoray provide driver BOM?
Yes — included in OEM quotations with run splits marked on layout PDFs.
Conclusion
Driver sizing errors show up as dim ends or nuisance trips — include electrical planning in the neon flex RFQ, not only product price.
