The CS300, 3-1/8-inch broad band motorized coaxial switch designed for any VHF or UHF broadcast application from DC to 862 MHz. This new motorized switch is a coplanar design that simplifies interconnecting transmission line requirements and allows for more compact equipment configurations with fewer expensive elbows. The switch is driven by a precise Geneva Drive mechanism that prevents deterioration of transmission system performance by maintaining precise 90-degree rotation for each activation.
The CS300 is available with either a 110 VAC or 240 VAC drive motor and control voltages of 12 VDC or 24 VDC. Manual operation is also provided by a hex drive Tee wrench through a hole in the switch case. If power to the drive is interrupted, the control circuit provides non-volatile memory such that the switch either holds its position or continues its transition upon re-application of AC power.
The CS300 is provided as a four port coaxial switch, the standard model can be adapted to three port configurations with the addition of a shorting cap. This allows the switch to be used in future configurations requiring 4 ports, by only removing the shorting cap
