OMS-DB09,9pin/15pin,Serial Signal Surge Protector,Data Signal Surge Protector
Product Description:
OMRDON DB Serial Data Signal Lightning Protector (SPD, surge protector) DB series surge protector is designed according to IEC and GB standards, mainly used in wired remote sensing, telemetry, remote control and so on using DB-type serial port equipment to provide line line between the line, line between the ground of the surge protection, applied to the lightning protection zone 1-2 area and 2-3 area, easy to install, no 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.
- Throughput capacity: 340A (8/20μS), high speed response (10-12 nanoseconds), low loss (≤0.3db).
- 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.
- When a lightning surge intrudes, there is no need to suspend the power-using equipment, and it does not affect the normal operation of normal equipment.
- Novel appearance design, small size, easy to install.
- High transmission rates and a wide range of usage frequencies.
typical application
- Wireline remote sensing equipment systems
- DB Serial Devices

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 opposite 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.
