Product Abstract:

Video, Power & PTZ signal protection; German brand core components; DC12V, AC24V, AC220V optional

Product Description


      BOSJK3/DC12 professional integrative multifunctional surge protector device. It is specially designed for s
  urveillance control system. It can prevent the surge and static damage the camera power, camera and PTZ
  equitment, the maximum discharge current can achieve 10KA, reacting within nanoseconds, so it can fully
  protect high-levels and expensive surveillance equipments
  1. Adopt multilevel protection circuit, low-level persistent voltage.
  2. Adopt the famous German brand core components, installation and maintenance is easy.
  3. It has huge flow capacity, sensitive reaction.
  4. Excellent performance, and low-loss insert.

Installation and Maintenance:
  1.   First, link the RS485 signal lines, power line with 4P socket (as the following picture), then plug in follow
        the arrow.
  2.   The BNC socket is the signal input, connect it to the signal line, the common outlet of BNC is the signal
        output, it connects the protected equipment. Do not connect in the opposite direction
  3.  Credibly connect the PE 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.
