Innovative RF Vacuum Contactor Introduced

Greenville, NC, 21 September 2007 –- LBA Technology announces the availability of the first new generation of RF power contactors in years.  These innovative RF contactors respond to the needs of broadcast, communications, and industrial radio frequency users of heavy duty RF relays.

The VC-1 high reliability vacuum contactor system is designed for versatility.  One series permits a wide range of operating voltages, and can be configured at any time for 1PDT through 4PDT operation.  It goes well beyond the capabilities of most currently available mechanical RF contactors, but is a direct replacement in many broadcast applications up to 50,000 watts.

Some of the key features of the VC-1 relay system are:

•           25 million cycle life, no open contacts
•           RF rated at 40A and 10 kV peak at 1 MHz
•           Easily switches 50,000 watts in a 50 ohm AM MW system
•           Rated DC to 30 MHz
•           Silent, vibration free switching
•           Direct substitution for popular mechanical latching RF contactors
•           Universal for 24, 110, 220 volts AC 50/60 Hz supply systems
•           Modular SPDT units, permits up to 4PDT, remote locating of modules
•           Includes interlocks and status lights

LBA Technology President Jerry Brown commented, “The VC-1 system brings a new era of reliability to radio broadcasters and other power RF users. The remote sealed contact modules will permit the design of more functional and cost effective directional antenna phasors and other equipment with reduced ongoing maintenance costs.”

LBA will have a VC-1 master and slave on display at Booth 528 at NAB Radio 2007 in Charlotte.
