Multi-volt control transformers produce dangerously high voltage on unused taps that is not clearly documented, creating a serious electrocution hazard.

Transformer manufacturers provide unclear or incomplete instructions about safe handling of multi-volt taps, leaving technicians to guess the correct neutral connection and risk high-voltage exposure.

Voltage calculator that predicts tap voltages based on input configuration

App Concept

TransformerSafe Pro

A mobile app and online database that provides clear, step-by-step safety and wiring instructions for multi-volt control transformers. Users scan the model number or enter specs to get precise diagrams, voltage warnings, and recommended tap isolation procedures. Replaces guesswork and vague manufacturer documentation.

Key Features

Scan model number or input specs to retrieve custom wiring diagram and voltage ratings
Built-in voltage calculator: shows expected voltages for each tap based on incoming line and neutral connections
Safety alert highlighting hazardous taps with minimum approach distances and PPE recommendations
User report system to flag dangerous transformer configurations and share field-tested safe wiring solutions

Target Users: Electricians, HVAC technicians, and industrial maintenance workers who install or service multi-volt control transformers in commercial and industrial settings.

Revenue Model: Freemium with $4.99/month pro subscription for unlimited transformer scans and community access, or $49.99/year for full access.
