Important notes
- Confirm driver voltage, minimum/maximum load, ambient derating, enclosure conditions, cable losses, and dimming compatibility.
- This tool does not select a certified product or approve an Australian electrical installation.
Formulas
- \(\displaystyle P_{\mathrm{load}} = P_{\mathrm{m}} \times L\)
- \(\displaystyle P_{\mathrm{driver}} = P_{\mathrm{load}}(1 + h)\)
- This is a preliminary constant-voltage sizing estimate; verify manufacturer data and licensed electrical requirements.
Estimate constant-voltage driver output capacity and current for an LED strip run.
LED Strip Driver Sizing Calculator is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
