UPS Circuit For Cordless Phones PCB


Posted on Feb 6, 2014

Circuit This circuit diagram of UPS is designed to use with a cordless telephones that cannot be operated during power failure. Since the ups is only meant for telephone, it`s output power is limiter to 1. 5W. This ups circuit is economical and can be assembled on a general purpose PCB. The circuit works around IC CD4047 which is an astable multivi
