2N - Safe construction modules

2N Safe is an ideal construction item for a very effective and demanding symmetric protection of electronic components against impulse over voltage. Each Safe module secures 1 pair of leads.

Types of Save modules

Safe2
A two-level symmetric protection against impulse over voltage.

Safe 3

A highly effective symmetric three-level protection against impulse over voltage with a reaction time of 1 ns and very low residual voltage behind the protection.

Safe 3+
A very effective symmetric three-level protection against impulse over voltage with a reaction time of 1 ns, very low residual voltage behind the protection and permanent resistance against 230V.

Safe PCM (secures 1 pair of leads)
A quick and very effective three-level protection against impulse over voltage on 1 pair of 2MBps PCM lines with extremely low residual voltage behind the protection.

Safe ISDN (secures 1 pair of leads)
A quick and very effective three-level protection against impulse over voltage on 1 pair of 2MBps ISDN lines with very low residual voltage behind the protection.

Extend-able multi-line protection

A modular and highly effective surface-mounted protection for up to 10 telephone lines. Thanks to its modular construction you can use a different type of protection for each pair of lines and replace the protection unit easily and quickly in the event of damage. A DIN latch can be used instead of a metal distribution board.

Metal distribution board
A metal distribution board for up to 5 modules (up to 10 telephone lines) designed for surface mounting. The distribution board can be equipped with 5 modules according to your choice.

Holder for 2 Safe modules
A holder can be placed into the metal distribution box for two Safe modules. The holder is equipped with two screwing clamps.

Types of multi-line protection modules

Module A
A complete two-level and symmetric protection for 2 telephone lines.

Module A+
A complete two-level and symmetric protection for 2 telephone lines with increased earthing current.

Module D
A HF filter protecting 2 telephone lines against disturbance in the range of long and medium waves. It is applied behind the protection module.

PCM Module
A quick and very effective three-level protection against impulse over voltage on 2 pairs of 2MBps PCM lines with extremely low residual voltage behind the protection.

ISND Module
A quick and highly effective three-level protection against impulse over voltage on 2 pairs of 2MBps ISDN lines with extremely low residual voltage behind the protection.
