Product Abstract:

Reacting within Picosecond level; be used all kinds of signal surge protection

Product Description


       BOS05YM2 lightning protector is applied for protecting the sensitive signal equipments such as communication
 special lines, telesignalisations, telecontrol signals, etc. It is widely used for protecting data transmission in
 computer communication system, monitoring control system, entrance guard interphone system, PLC automatic
 control system, and fire prevention alarm system. It can avoid serious damage which made by thunder and lightning
 induced tension, electrical network voltage undulation disturbance, static discharge, and impact surge voltage.
 Typically used for lightning and surge protection
  1. BOS05YM2 communication signal surge protector is designed according to the standard of IEC surge protector.
  2. The joint form is standard screw grip, it can protect 1~2 groups of circuits..
  3. There are various choices of quota voltage, also, the installation and maintenance is very easy and convenient.
  4. 3-levels tandem type, the Maximum discharging current can achieve 10kA, reacting within Picosecond level, it can
       fully protect those equipments which use the latest semiconductors

Installation and Maintenance:
  1.    The surge protector device should be linked between the signal line and the protected equipment.
         Connect manner is: 1 to 1, 2 to 2.(the follow picture is the example)
  2.   "In" must be connect the signal line;"Out" must be connect the protected equipment, do not connect in the
         opposite direction.
  3.    The PE line of the lightning arrestor must strictly be connected to the lighting protection system at the
         equipotential, else, it will influence the working performance.
  4.    Credibly connect the grounding lines. This product need not pay special attention to maintenance, but please 
         waterproof notice. When the system working goes wrong, please check the surge protector after removing it. If 
         unused thesurge protector condition,but the system working normal, meaning the surge protector is damaged,
         please change the surge protector.
