SURGE PROTECTIVE DEVICES
RSP-485 Series
These are surge protection devices designed for
RS-485, protecting driver/ receiver ICs in
input-output terminals, from surge such as lightning.
Features
● This protector consists of RSSA (silicon surge
absorber) and R·A·V.
● Excellent response time and endurance.
● Small gain loss in long distance communication
by the use of common mode choke coils in
impedance blocks.
● PCB mounting type, terminal block type and DIN
rail box type available.
Electrical Specifications
● Maximum circuit voltage: 6.05V(L-G)
● Clamp voltage: 15Vmax. (@1.2/50μs-1,000V)
● Repetitive surge guaranteed: 8/20μs-1,000A 100
