BA-310 Series, Blower Assemblies
The BA-310 Series consists of two high frequency fans, with vertical side baffles to direct air over the loads radiator fins. The blower doubles the normal RF input rating of the installed load, e.g. a 2.5kW load can dissipate 5 kW. The BA-310 Series has a Thermoswitch wired in parallel with the power switch. When a load equipped with a fan-control Thermoswitch is properly connected, the blower will automatically turn on in response to a rise in load temperature. This system provides automatic operation suitable for reject load service.

Interlock Thermoswitches are recommended when using the blower assembly.
