OMS-RJ11/2S,0MS-LSA/10,110V,10KA telephone lightning protector, Cologne lightning protection row, telephone/cologne distribution frame lightning protection
Product Description:
OMRDON OMS-RJ11/2S(4S),0MS-LSA/10 telephone lightning protector is designed according to IEC and international standards, mainly used for telecommunication data communication signal line and its equipment (such as: telephone, programmable telephone, fax machine, Cologne distribution frame) lightning, over-voltage protection, easy to install, without special maintenance.
The product is encapsulated in a shielded case with a built-in high quality high-speed overvoltage protection device, which provides efficient protection and defense against lightning high-voltage pulses induced on the signal line.
Functional Features::
- Large through-current capacity, low residual voltage and fast response time.
- Internal two-stage series linkage protection, low residual voltage, long service life.
- With triple protection function of over-current, over-voltage and clamping, fast response speed.
- Low loss, superior signal transmission performance.
- Provides wire-to-wire and wire-to-ground full protection modes.
- Fast reaction time, less than 1ns.
typical application
- telephones
- fax
- ADSL line
- Krone Distribution Frame
- Fire Alarm

Installation Precautions
1. The output ports of this series-type lightning protector are connected to the protected equipment.
2、Positive and negative lines should not be connected to the reverse or wrong, remember not to work with electricity.
3, lightning protector installed in the front of the protected equipment the closer the better.
4. The equipment needs to be inspected regularly, and the product must be replaced immediately after deterioration.
