 All of our products can be configured to your specific requirements. Customers are invited to work with a design engineer to define the output, input range, protection limits and dimensions of the power solution which best meets their project needs. This can frequently be accomplished without NRE. Use the contact form to submit a request, or contact us at (603) 267-8865 to discuss your requirements. Configurations created for specific requirements will be assigned a new variant part number.
