Mini DC UPS
Uninterrupted DC power for network equipment.
A compact DC UPS with an 82 Wh Li-ion battery and four outputs that keeps modems, routers and IP cameras running through power cuts.
Every power cut takes the network down.
Modems, routers and IP cameras restart on every short outage, and AC UPS units are bulky and waste energy converting power for devices that run on DC. Each device also needs its own voltage and connector.
One smart DC source for every device.
Adapter power goes straight to the equipment while the internal battery charges. If mains fails, a hardware power-path stage, independent of software, switches to the battery with no shutdown.
Technical details
Hardware power, smart control.
Power continuity is handled entirely in hardware; a digital control unit handles monitoring, output control and the interface.
