The Valcom Power Unit (VPU) calculator is an easy-to-use tool to assist you with the minimum power supply requirements in your system design. Simply select the products and quantities including speakers, horns, accessories, and paging controller to be utilized in your application.

Based upon your VPU total, select the quantity and power supplies needed.
