DESCRIPTION
- Current limit protection
- High surge capability
The LH1529A and LH1529B telecom switches consist of an
optically coupled solid state relay (SSR) and bidirectional
input optocoupler. The SSR is ideal for performing switch
hook and dial-pulse switching whilst optocoupler performs
ring detection and loop current sensing functions. Both the
SSR and optocoupler have an isolation test voltage of
- Clean bounce free switching
- Low power consumption
- High reliability monolithic receptor
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
5300 VRMS
.
APPLICATIONS
• General telecom switching
- On/off hook control
- Dial pulse
AGENCY APPROVALS
UL1577: file no. E52744 system code H, double
protection
BSI/BABT: certification no. 7980
- Ring current detection
- Loop current sensing
