Clean Power is Essential

Applying Good clean power to the board in essential for the operation of the board.  Not only for the switching of the relays but the firmware that processes the commands.  Without good steady clean power from a regulated power supply the board simply will not function correctly.  More that one troubleshooting question has turned out to be from someone who says they are using a power supply that they had "just laying around" and it was not sufficient enough to provide the power needed to operate the board.  We also carry an international power supply with interchangeable adapters for international customers.

Attention: SHARING POWERS SUPPLIES WITH INDUCTIVE LOADS

Most NCD devices are powered from a 12V power supply. NCD Devices REQUIRE a CLEAN Computer-Grade Regulated Power Supply. The power supply used to supply power to NCD Devices should not be shared with inductive loads. For instance, you should never use a single power supply to power a NCD Device and a 12V DC Motor. Doing so will introduce extremely high-voltage spikes that will damage the logic and power regulation portions of NCD devices, and in many cases, the NCD controller will NOT BE REPAIRABLE. The only known exceptions to this warning are customers who are working in automotive or other battery-powered applications where induction is naturally suppressed by integrating a large battery into the design. Filtering circuits may also be used to clean the power supply before entering the NCD controller, provided they are properly designed to work with your particular inductive load. Induction suppression capacitors may assist in the filtering of the power supply, but more study is required to determine their effectiveness at cleaning the power supply before it enters the NCD device.
