A0609CA2LRP
Description
The A0609CA2LRP is a LCAS protector that does not
require an external voltage reference. It specifically
provides protection for a balanced ringing system with a
ringing voltage range of +54 volts and -78 volts.
This three pin modified DO-214AA solution provides
a smaller footprint and lower component count than
the typical dual polarity programmable SLIC protector.
This new overvoltage protector is applicable for
WLL ( Wireless local loops), VoIP (Voice over IP) and
regenerated POTS (Plain OldTelephone Systems)
applications.
