TRSS-485 SPD

RS485 surge protector. The surge protector is connected in series in front of the protected equipment, and is mainly suitable for communication lines, remote signaling, measurement and control systems, access control intercom systems, automatic control systems, security systems, etc., which can effectively absorb the energy generated by surges Impact, and introduce energy into the earth through the grounding cable.
  1. Protect a pair of signal lines from lightning surge
  2. DIN rail installation saves a lot of space
  3. The maximum discharge current is 10kA.
  4. A variety of protection voltages are available, such as 5V 12V 24V 100V
