Mounting Considerations

The AX1500’s heatsink is located at the bottom of the board. This requires therefore that the board be mounted with spacers that are at minimum 0.6” (15mm).

0.6" (15mm) or longer spacer

Thermal Considerations

The AX1500 is equipped with an aluminum heatsink beneath the power transistors, ensur- ing sufficient heat dissipation for operation without a fan in most applications.

When mounting the board, and if current is expected to be above 15A on average, ensure that there can be a natural or forced convection flow to remove the heat. Mounting the
