Protects your system when cooling fails.
Forced-Air-Cooled 10 kW Series RF Loads
The 8630B Series Moduload® is a compact, forced-air cooled RF load capable of dissipating up to 10 kW of continuous power. Engineered for transmitter protection, testing, and load substitution in high-power systems, this 50-ohm termination offers broadband performance to 1 GHz and integrates seamlessly into rack or floor-mounted environments.
An onboard interlock control circuit automatically protects both the transmitter and load in the event of blower or AC power loss, helping prevent damage during extended operation. With selectable AC input options (115 V or 230 V), the 8630B Series provides high-performance RF dissipation without the complexity of water cooling.

1 Gal. PMX-200 Silicone Oil Coolant
5-1134-3
RF Load Coolant is an alcohol with two -OH groups (a diol), a chemical compound widely used as an antifreeze. In its pure form, it is an odorless, colorless, syrupy liquid.
Load Protection Switch
8640A930-1
Safeguards Bird 3-1/8" water-cooled Moduloads® by blocking RF power until proper coolant flow is detected. It streamlines interlock protection without wiring directly to the RF source, reducing setup time and preventing costly equipment damage.
Why RF Pros Choose Bird Loads
Accuracy, protection, and lasting performance—Bird loads deliver where it counts. From convection to water- and air-cooled designs, each is built to absorb full RF power, minimize VSWR, and perform reliably in the toughest environments.
