DCT-1 and DCT-2 DC Power Insertion and Recovery Modules

 

• The DCT-1 and DCT-2 power insertion units are used to insert DC power into, and remove DC power from, a coaxial cable that is carrying RF power to a plasma tube or other load. This inserted DC power may be used to operate a cooling fan for the LC31 link coil couplers or a plasma tube. One or more fans or other loads may be operated with power supplied through the DCT-1 or DCT-2 power insertion units, depending on the voltage and current requirements of the load.

• The DCT-1 and DCT-2 power insertion units are normally used as a pair, with one unit being used to insert the DC power into the coaxial cable, while the other unit removes the DC power from the coaxial cable to power the load.

• The difference between the DCT-1 and the DCT-2 is that the DCT-1 feeds DC power to both of the RF terminal blocks, while the DCT-2 feeds DC power to only one of the RF terminal blocks.

•  The DCT-1 is used with amplifiers and loads that have internal DC blocking capability built into them, such as the PA1, PA2, PA3, SPA4, and SPA5 amplifiers, and the LC31 coupler.

•  The DCT-2 is used with amplifiers and loads that cannot have a DC voltage applied to them, such as some solid state amplifiers, antenna tuners, and antennas that have a direct DC path to ground.

• All combinations of DCT-1 and DCT-2 are acceptable. A DCT-1 or a DCT-2 may be used with another DCT-1 or a DCT-2, depending on the circuit requirements. A DCT-1 may be easily converted to a DCT-2. Likewise, a DCT-2 may be converted to a DCT-1 if needed. Please contact us for further information about the conversion.
