CS300

CS300 Series 3 1/8 inch Broadband Coaxial Motorized Switch; Frequency range from DC to 860 MHz; Non-volatile position memory; VSWR <1.05:1 typical; Isolation > 55 dB typical; 3-1/8 EIA male ports; Three port application require only the addition of a shorting cap; Geneva drive mechanism provides precise position; control; Available with 115 Volt or 240 Volt AC motors; 12 or 24 volts DC control voltage; Mount in any orientation; May be operated manually; 3 or 4 port configuration

CS400

CS400 Series 4 1/16 inch Broadband Coaxial Motorized Switch; Frequency range from 54 to 860 MHz; Non-volatile position memory; VSWR 1.05:1 typical; Isolation  50 dB typical; 4-1/16 male ports; Three port application require only the addition of a shorting cap; Geneva drive mechanism provides precise position; control; Available with 115 Volt or 240 Volt AC motors; 12 or 24 volts DC control voltage; Mount in any orientation; May be operated manually; 3 or 4 port configuration

CS

ERI CS series coaxial motorized switches are designed for operation within FM,VHF, and UHF broadcast systems. The switches are engineered to provide high capability and long life. A Geneva drive mechanism provides exact 90 degree rotation of the contacts. The switch drive can be powered by either 115 VAC or 230 VAC. Control voltage can be either 12 VDC or 24 VDC. Manual operation is provided via a hex drive Tee Wrench through a hole in the switch case. If power to the drive is interrupted, the control circuit provides involatile memory so that the switch either holds its position or continues its transition upon re-application of AC power.

SW

SW Series RF Safety Switches; Low VSWR; Fast mechanical operation.; Can be installed in tightly spaced coaxial runs; Large visual decals illustrate switch positions; Activation lever can be padlocked or tagged in engaged or disengaged positions; Internal sensing switch for remote signaling and/or transmitter interlock control

WS

ERI WS series Waveguide motorized switches are designed for operation within UHF broadcast systems. The switches are engineered to provide high capability and long life. A Geneva drive mechanism provides exact 90 degree rotation of the contacts. The switch drive can be powered by either 115 VAC or 230 VAC. Control voltage can be either 12 VDC or 24 VDC. Manual operation is provided via a 9/16” socket head that is accessible through a hole in the switch case. If power to the drive is interrupted, the control circuit provides involatile memory so that the switch either holds its position or continues its transition upon re-application of AC power.

CP

QUICK-Patch Patch Peanls; For systems requiring premium performance, ERI provides the QUICK-Patch Coaxial Patch Panel. Known for its unique U-Link release and capture system, the Quick Patch Coaxial Patch Panel offers the easiest and quickest U-Link remove and replace action in the industry. < 1.04:1 VSWR; 90% of line size Power Rating; FM,VHF, UHF Frequency Range; 50 ohms Impedance;

CDX30

CDX30 Series Precision Directional Couplers; Balanced directional coupler designed for stand alone test port applications or for use with ERI’s Monitoring and Protection System.; Available for 1-5/8, 3-1/8, 4-1/16, and 6-1/8-inch (50 ohm) transmission line sizes; Models available with one (1) to four (4) coupling probes; Includes coupling probe termination load.

CD

CD Series Coaxial Directional Couplers from 1 5/8 inch to 7 3/16 inch available in 1, 2, 3, and 4 port Type N Female configurations. Adjustable and saddle type (field install) versions available. -30 to -70 dB Coupling Range; 1.03:1 or better VSWR; 30 dB or better Directivity; 50 to 860 MHz Frequency Range;

CZ

ERI CZ series UHF coaxial break-away sections, unique multifunction units, employ a harmonic filter, four adjustable directional couplers and the capability to separate the output of the transmitter from the transmission line system simply and effectively.

CL

ERI CL Series UHF Coaxial Loads offer a proven design for handling high power at low cost. The load employs a solution of glycol and water as both coolant and resistive material. The power dissipated by the load heats the solution and is removed by the coolant’s constant flow. The loads are extremely rugged since the resistor is liquid and no finger contacts are used. A dielectric transformer on the inner conductor distributes power evenly throughout the coolant and provides excellent thermal stability over a wide range of temperature and power levels. The loads can be furnished with ERI replaceable element dual directional couplers upon request.

WL

ERI uniquely designed tapered Waveguide water loads utilize a technique involving two coaxial dielectric tubes that carry the water/glycol solution (which functions as a heat dissipater and RF absorber). The WL Series provides an efficient and low cost method for dissipating unwanted RF. As an option, a tuning section may be added. Any combination of coolant inlet and outlet adapters is available as well.
