Common Concerns Answered
What if my devices draw more than 3 Amps?
The Newmar 24-12-3 is rated for 3 Amps continuous output. For higher amperage requirements, alternative converters such as the Blue Sea Systems 7610 HD (10A) or Victron Energy Orion-Tr Smart 24/12-12 (25A) should be considered.
Can this converter be used with a positive ground system?
No, this unit is specifically designed for 12V negative ground systems. For positive ground applications, an Isolated Series converter from Newmar would be required.
What is the return policy for this converter?
This product may not be returnable to the original point of purchase. For any issues or returns, direct contact with the manufacturer, Newmar Power, is typically required.
