As of January 1, 2016, the hot buss in our model PD4045 and PD4060 is no longer supplied by Progressive Dynamics as it is not required for the proper function of the power center. If you have any questions, please feel free to contact our Service Department at 269-781-4242.

Note: Progressive Dynamics Inc. converter chargers are being advertised on Amazon, Yahoo and Face Book under the name of Progressive International. This name is to imply that Progressive Dynamics is somehow involved with Progressive International and we are not. The real Progressive International sells RV kitchen products and not converter chargers. Progressive Dynamics and the real Progressive International only sell through authorized RV distribution companies and RV dealers.
