RF SOLUTION-CITEL
1 to 4-pair Surge Protection Boxes
BP1, B280, B380, B480
The BP1, B280, B380, B480 units are designed to protect,
against surge voltages, terminals connected to telephone or
data networks.
The electrical diagram is based on GDT and clamping diodes
to guarantee a maximum efficiency.
These boxes are available for 1 to 4 pairs : the protection
printed circuit is removable for easy and fast maintenance
(removable protection circuit S180.., S280.., S380.., S480..).
These compact boxes are designed for wall mounting and
screw connection. Versions exist for most telephone and
datalines.
Special versions are also available for the combined protection
of data transmission and remote power lines(e.g. B480-24D3/
A12 : 3 x 24V transmission pairs + 1 x 12Vdc power supply).
