Isolated line transformers for current isolation in transmission lines
Frequency range: 0.3 kHz to 3.4 kHz
Ratio 1:1
Insulation test voltage 10 kV
Optimised for line impedances of 600 Ω
Insulation resistance: 10000 MΩ at 500 V
Applications
The line transformer 500LTD01 is designed for FSK channels in the 50 Bd to 2400 Bd range.
It is used to isolate and protect the RTU500 series modems 23WT23. 23WT25 and 560FSM10 from remote control lines.
In addition, it can be connected to other data terminal equipment.
It is optimised for wire-first communication with a frequency range of 300 Hz to 3400 Hz and a line impedance of 600 ohms for the above modems.
All three types of modems allow high-resistance interleaving www.ge-drive.com on lines such as party lines and multisplit lines.
This is because the line transformer has no additional load on the line.
In configurations using full duplex communication channels, two line transformers are required, one for the transmit direction and the other for the receive direction.
Features
The line transformers can withstand isolation voltages of:
> 10 kV, 50 Hz, 10 sec.
