Wire pair protection, in-line installation, screw terminals. In-line impedance 10 ohms. For signal voltages 5 to 170V peak (AC and DC). Bipolar operation, instantaneous and automatic. Line terminals carry the surges, equipment terminals are protected. Mounting legs connected to ground. Surge current rating 15,000 amperes for 8/20 µs and 750 amperes on 10/1000 µs wave.
Data and signal lines protector. Maximum signal 28V peak line to line and each line to ground. In-line connection din rail mount. Clamping voltage starts at 30V. 5 stages of protection provided. Maximum surge current 30 KA, 8/20 µs wave. Either polarity of surge equally clamped. Temperature -55° to 80° C ambient. Note : Model LPC 11889-25 is for signal levels to 28V peak. The LPC 11889-series are available for data and signal levels from 5V to 240V peak. Inquire for proper "dash" number for your application.
Miniature wire pair protector (4-20 ma transmitter protector). 2 lines and ground. 0.50" X 0.68" X 1.25" H. AWG 16 insulated leads. Protection maximum 30 KA, 8/20 µs line to line and each line to ground. Connections across the lines and to ground at or inside the equipment enclosure. Response less than a nanosecond. After initial breakdown clamping voltage immediately drops to 30V an any surge up to 30 KA of current. Automatic restoration to the line voltage after the surge passes.
Inquire regarding other available voltage ratings.
The LPC 10643-485-3 is a 5 terminal device inserted in-line for protection of equipment operating on a wire pair of 0-9 V peak. Mounting is on wire pair 66 blocks. Applications include RS422 twisted wire pairs, RS485, and other applicable wire pair systems. Mounting utilizes standard spacing (0.40 in.), single clip terminations, and screw stud ground terminal. Lightning and surge protection is provided line to line and each line to ground. Either polarity of the transient is equally clamped. Equipment to be protected is connected to wires E1 and E2. The line side (transmission line experiencing surges) is connected to wires L1 and L2. In-line resistance is 10 ohms in each line.
