Need a transformer to convert 120V single-phase service to 240V for an electronic sign without trenching 150 feet through concrete.

No readily available transformer product for step-up 120V to 240V with dual 20A outputs for temporary or retrofit installations; existing solutions require expensive trenching.

App Concept

StepUp Dual 240

A transformer that takes a single 120V service input and provides two 20A 240V circuits for electronic signs or other 240V equipment. Eliminates costly trenching by enabling use of existing 120V lines to produce 240V output.

Key Features

Input 120V single-phase, outputs two 20A 240V circuits
Compact and weatherproof for outdoor installation
Built-in overload and surge protection
Easy wall-mount or pole-mount installation

Target Users: Electricians and electrical contractors needing to power 240V equipment where only 120V service is available, especially in retrofit or concrete-heavy environments.

Revenue Model: $500–$800 per unit one-time sale, with volume discounts for wholesale distributors.
