Normal 0 false false false EN-US X-NONE X-NONE TACTICALRADIOGEAR.COM PROFESSIONAL CONVECTION COOLED DUMMY LOAD The Tactical Radio Gear, SMART LOAD, is a compact, portable, light-weight Dummy Load, capable of handling >100 Watts “barefoot” with no fan, and >500W power levels with the fan is running. SMART LOAD is air-cooled/forced air cooled; there is no transformer oil to mess with; or hot heat-sinks to worry about. SMART LOADS, are the perfect, dummy load, for the ham who does not require a much larger load (watts). SMART LOADS are handy for tuning, adjusting, and fixing your radio equipment. The SMART LOAD is compatible with most amplifiers, transceivers, and transmitters from DC-2GHz. The RoHS Compliant; ±5% Tolerance, 50 Ohm terminator resistor, is rated DC-2GHz @ 250W with a 1.2 VSWR over the frequency range. CONSTRUCTION The termination resistor is mounted on a 2” x 1.5″” x 1/4” thick, solid copper; silver coated heat spreader. A DC brushless fan, with ball bearings, generates a sufficient volume of airflow, for effective cooling. The SMART LOAD comes with a DC Power cable with a 2.1mm connector; and a 110 VAC/VDC wall adapter, with a 2.1mm connector to power the fan. The fan is powered by a DC-DC Variable Volt Regulator: Input 3.0-35V & Output 1.5-35V Adjustable Buck Converter, Power Supply Module. Intermittent Power Rating: >100W/500W Impedance: 50 Ohm +/-5% Connector Type: UHF female, SO-239 Type of cooling: Air cooled & Forced Air Cooling Frequency Range: 0-2GHz VSWR: 1.2 over the frequency range. Width: 3.900 in Height: 1.900” Depth: 4.400” Weight: 1LB. The heat sink is one of the most fundamental components in cooling electronic devices. For any heat source that cannot be cooled through its own conduction cooling, a more efficient cooling system than just a heat spreader is required. The SMART LOAD utilizes both heat sink, and heat spreader approaches; with convection cooling, to move heat away from the source; and dissipate it through an optimized conduction & convection cooling arrangement. The Heat-sink makes direct contact with the heat source (termination resistor) and spreads the heat from the hot spot to the fins. Aluminum has a thermal conductivity of 235 watts per Kelvin per meter; where a fan directly above the heat-sink exhausts the heat (convection cooling) forcing cooler air across the fins, creating turbulence and increasing the cooling performance of the heat sink. Additionally, the termination resistor is mounted directly to a 2” x 1.5” x .250” Copper heat spreader; necessary for high performance applications; due to its high thermal conductivity at 400 watts per Kelvin per meter; The heat spreader will absorb the initial thermal shock, from the application of higher power levels. contact ‘tacticalradiogear.com’ for additional information.
