1830-A110 Datasheet, PDF (1/2 Pages) Bourns Electronic Solutions – Protection Assembly, Rail Mounted

Features
I Convenient kit for T1/E1 stations
I Meets the T1 pulse mask as per ANSI
T1.403 and the E1 mask per ITU G.703
I The protectors utilize PTC resistor
technology for automatic resetting
overcurrent protection and gas discharge
tube technology for overvoltage
protection
I Both protectors can be on-site configured
for either powered or unpowered spans
I Simplicity of DIN-3 rail mounting; the rail
also serves as protector ground
I Vibration proof screw-type clamping
connector interface
Model 1830-A T1/E1 Protection Assembly, Rail Mounted
Bourns Model 1830-A T1/E1 Protection Assemblies provide secondary overvoltage protection for multiple T1 or E1 lines.
DIN-3 Rail Mounted and able to accommodate future add-on modules, the assembly is designed to provide maximum surge
protection caused from direct and induced lightning surges, power line disturbances and ground potential rises.
Common installations of the 1830-A are power cabinets located in wireless base stations or other larger telecom service
entrance terminals.
