产品描述
NKP-TEL-6J
The NKP-TEL-6J surge protector is designed to protect analog signal processing equipments, connected directly before the analog signal inputs to be protected(0~20mA, 4~20mA,0~5V, 0~24V), like A/D samples, A/D conversion, PLC control system, transmitting output system, etc. Featured with in/out terminals connector. It uses a combination of MOV, 3-electrode gas discharge tube and fast clamping diodes to avoid the risk of surge voltage coupling along the conductor route between surge protector and interface.
Main Features
- Analog signal surge protector
- Terminal connector
- 1 line, 2 wires protected mode
- Ultrafast response time <1ns
- Systematic use of MOV, 3-pole gas tube and fast clamping diode
- Industrial thermal plastic enclosure

*Installation Notes
- Must disconnect power before installation, no hot-line operation is allowed, and better to under the guidance of professional electrician.
- For best performance, mount protector in serial with the equipment it is protecting as close as possible, and better to install one protector at each end of the data line.
- The ground wire on the product (if included) must be attached directly to the metal chassis of the equipment to be protected. The length of the grounded wire is not to exceed 11 inches.
- No special maintenance is needed, however regular inspection is needed, especially during storm seasons.
