Power Distribution Splitter for Signage Class 2 Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical signage systems require excessive labor and material due to the need for multiple power supply units and complex wiring to comply with Class 2 UL standards, as they must distribute power below 60 W/12V or 96 W/24V using multiple leads, leading to inefficient installation and repair processes.
Innovation Solution
An electrical power distribution splitter that receives high wattage power and splits it into multiple low output wattages using an IC electric board, allowing a single large wattage supply to feed multiple lower wattage circuits, thereby enabling Class 2 UL standard compliance with reduced system components and simplified installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual power supply units are used to distribute power to multiple circuits, then Class 2 UL standard compliance is achieved, but system complexity and installation labor increase significantly
Solution Approach 1:
The power distribution function is segmented into multiple independent Class 2 compliant output circuits within a single device. The splitter receives Class 1 input power and internally divides it into multiple Class 2 compliant outputs, each capable of independently powering different circuit loads while maintaining safety standards compliance.
Solution Approach 2:
Multiple individual power supply units are merged into a single integrated power distribution splitter device. This consolidation maintains the functional equivalence of multiple separate units while eliminating the need for multiple separate installations, reducing overall system complexity and installation labor.
2Reliability
If multiple individual power supply units with manual connectors are used, then Class 2 UL standard compliance is achieved, but installation time and labor costs increase
Solution Approach 1:
Manual screw-on wire nut connectors are replaced with quick-connect electrical interfaces. This substitution eliminates the need for manual wiring and mechanical fastening operations, allowing for rapid connection and disconnection of power circuits while maintaining secure electrical contacts.
Solution Approach 2:
The power distribution splitter is pre-configured with multiple ready-to-connect output interfaces during manufacturing. This preliminary preparation eliminates the need for on-site wiring and connector assembly, allowing installers to simply connect pre-assembled units to the target circuits.
3Reliability
If multiple individual power supply units are used, then Class 2 UL standard compliance is achieved, but material costs and component quantity increase
Solution Approach 1:
Multiple separate power supply units are merged into a single integrated device that provides equivalent total power capacity. This consolidation reduces the total number of components from multiple individual units to one unified splitter, directly reducing material costs and component quantity while maintaining the same functional output.
Solution Approach 2:
The power distribution splitter is designed as a universal device that can replace multiple different power supply units. A single splitter unit provides multi-functionality by delivering power to multiple different circuits simultaneously, eliminating the need for circuit-specific power supply units.

AI summary
An electrical power distribution splitter is designed to receive high wattage electrical power, e.g. 80 W-600 W, and then to “split” that power into multiple low output wattage electrical power, e.g. 60 W/12V or 96 W/24V. An IC and circle board in the distribution splitter is used to reduce output power in this manner. The result is the ability to input a single large wattage electrical power supply to a distribution splitter which then outputs multiple lower wattages to a variety of individual different circuits, and, in so doing, a Class 2 UL power supply can be utilized. This is especially important in the signage industry where, for example, one large wattage power electrical supply feeding into the power distribution splitter can supply multiple smaller wattage power to different circuits in one sign.
