Dual power supply! RF signal automatic switch with manual switching capability and output for operation contacts.
The "STSW-21WJR" is an RF signal automatic switch that inputs RF signals from antennas, transmission lines, etc., into two systems: main and sub. When the detection level on the main side drops below a specified threshold, it automatically switches to the sub side. It is equipped with an AUTO/MANUAL button, allowing for manual switching as well. The power supply is redundant, and by inputting from a separate power line, you can use it with peace of mind. 【Features】 ■ Output with operating contacts ■ Redundant power supply ■ Automatically switches back to the main side when the level on the main side returns to the specified threshold ■ Equipped with an AUTO/MANUAL button for manual switching ■ Can be used safely by inputting from a separate power line *For more details, please refer to the PDF document or feel free to contact us.
