SC and PSC battery-backup switching power supplies
UPS Series covers two battery-backup sub-series built for security, CCTV and backup-power systems. SC series (SC-35 to SC-180) switches to battery with a 0.1S delay on mains failure, while PSC series (PSC-60 to PSC-500) transfers with no delay for uninterrupted DC loads. Both sub-series provide a regulated DC output plus a built-in battery-charge channel, ready for external backup batteries.
SC series switches from AC to backup battery in 0.1S - a controlled, cost-effective break for loads that tolerate a short transfer gap.
PSC series keeps DC output continuous during mains failure with no switch-over delay, protecting sensitive CCTV and security equipment.
Both sub-series include a dedicated battery-charge output with B+/B- terminals, so an external backup battery is charged and ready automatically.
Every unit passes full aging and load testing on 48-slot racks before shipment, with CE / RoHS certification on the product lines.
