Data Line Surge Protector
LPS DL-2/7.5
Specification
Features:
-
Ideal for RS485, RS 422, RS 423,
Ethernet signal of instrumentation interfaces and equipment
such as servers, card reader controllers, lift controllers,
twisted pair CCTV circuit, etc
-
Protects sensitive data networks
against lightning induced surges without impairing the
system normal operation or cause excessive in-line
resistance
-
DL series employs multistage
protection with GDT for primary protection then linked by a
second stage series impedance and semiconductor voltage
dependant device to provide unsurpassed performance in
lightning surge protection
