dilshan·12v-automatic-ups·design/ups-12v.kicad_pcb

12v automatic ups is an open source PIC PCB design by dilshan: a 2-layer, 131.8 × 99.9 mm board with 72 components (53 distinct parts). It is built around the LM350T, PIC16F688, PC817, LM2576T-12 and more. Filed under power & battery.

12V Automatic UPS system

This 12V uninterruptible power supply initially designs to drive my fiber optic modem/router. The key reason to build this power supply is to get continuous internet and phone connection during power failures. Core components of this power supply are a constant voltage charger, 12V DC power supply, AC line monitoring unit, and 12V high capacity sealed lead-acid battery. The entire system designs using locally available components.
