DC Power Video Data Transmitter , Single Channel Video Power Balun
Description:
VB303T transmits video signal to VB303R, at the same time, VB303R provides DC 36V power supply for VB303T, then VB303T converts the received DC 36V power supply into DC 12V to provide stable DC 12V power supply for camera or other headend equipments with maximum loading capacity of DC 12V (500mA) and also provide a channel of RS485 control interface, so it can complete the transmission of video, power supply and control signals on this line only to lay a Cat-5 unshielded twisted pair wire, which can greatly simply the wiring project and save wire use quantity (VB303T only can be used with VB303R)
Features:
- Adopt differential signal transmission with excellent anti-jamming ability
- Save project cable expenses, it can complete the transmission of video, power supply and control signals on this line only with one Cat-5 unshielded twisted pair wire
- It can provide stable DC 12V power supply for the headend camera or other electro-equipments only to provide a DC 36V power supply at the receiving terminal (master control room) in the whole transmission system without providing another power supply for the camera and other DC 12V electro-equipments and realize remote power supply.
- Built-in transient suppression protection
- The farthest transmission distance can reach 1500m when VB303R is used with VB303T (this series shall be in matched use and shall not be used with other types of transmitter)
The transmission distance has relation with the total power of the camera and other headend equipments, for the details, please refer to the following table:
