12V DC Power Strip Printed Circuit Board
The Ham Radio Workbench 12V DC Outlet Strip Printed Circuit Board allows you to build a device to share a single 12V power source with up to four other devices.
This board is designed to support communication activities using a single 100 Watt HF radio which does not operate at 100% duty cycle at full power, or a single 50 Watt FM VHF/UHF Radios that draws approximately 16A at 13.8VDC in QSOs.
The completed project features:
- Designed for Anderson Powerpole Connectors
- Total current capacity not to exceed 25 Amps @ 12V nominal total across all ports
- Four fuse holders that accept standard or low profile ATC fuses
- Polarity indicator for the 12V input to verify that your source is wired correctly
- An LED will light to indicate when a load is connected to an output port with a blown fuse
This item includes the Printed Circuit Board Only.
It is not recommended to operate at the Operational Maximum Current of 25A at 13.8VDC for periods longer than 5 minutes, as the copper traces of the 12V DC Outlet Strip can become hot, exceeding temperatures of 150F after an extended period (5 minutes or more) of constant 25A current draw. Temperatures can approach 200F when a constant 25A at 13.8VDC are drawn for periods of 10 minutes or more.
