The in-built circuits put in use high quality gas arresters for high transient current handling capability. Moreover, the secondary stage of silicone based transient suppressors allows high speed clamping with only a small margin above maximum operating voltage. The secondary transient suppressors have been arranged to give very low line to screen and line to ground capacitance. Series impedance is included to coordinate the two stages. This impedance has been kept at a low value to minimize insertion loss. Low in-line impedance combined with the low capacitance arrangement of the transient protection has allowed LPI to provide a protector with minimal affect on signal transmission. These can be installed in the following manner: • Connect transmission cables to the input and output of the unit via BNC plugs • To ensure the correct operation of the unit, a suitable earth connection must be made between the 3mm brass earth stud and the frame earth, ensure this earth path is low resistance in accordance with local regulations. |
| GSM 7-16 Protector | | |
| We are providing to our clients, GSM 7/16 quarter wave stub surge protector designed for GSM cellular frequencies from 890 - 960 MHz providing surge protection against transient over voltages due to direct, indirect lightning strikes and earth potential rise caused by lightning.
