7. THERMAL MANAGEMENT
The SpeedVal Kit half-bridge motherboard comes equipped with a cooling fan (Sanyo #
9G0612P4S0011 or equivalent). The cooling fan can be controlled manually with switch S1. If one of the
optional control boards is installed, the control board will start the fan automatically when a power
test is run.
The motherboard has two connectors to power fans. Fan 1 (CON14) connector provides power to the
included fan. Fan 2 (CON15) connector provides power to the optional buck boost filter board.
