155HS Series Digi.Guard II - MSP® Heavy Duty Station Protector
®
Bourns Model 155HS Digi.Guard II Multi-Stage Protector is a new generation telecommunications Station Protector designed to be
the best all around choice for protecting copper pair voice-band and high speed data circuits. Combining the strengths of Gas Tube
and solid-state protectors, the Model 155HS integrates three advanced protection technologies: a proprietary sixth-generation Gas
Tube, a precision matched metal oxide varistor and a patented Switch-Grade Fail-Short mechanism.
®
Bourns 2378-35 can be used universally for POTS and high speed data, e.g. ISDN, ADSL, ADSL2+, VDSL, VDSL2, other xDSL
®
®
protocols and high speed Ethernet. Bourns MSP technology provides unparalleled overvoltage protection with low loss on paired
copper communications circuits. The Model 155 is the most economical, reliable and best performing choice for overvoltage
protection of paired copper communications circuits.
