Overview
Not a desktop power strip with a battery, the APC Smart-UPS SC is a one rack unit lithium-ion UPS built for network gear and point-of-sale devices. Mounted in a short-depth rack, it protects against power disturbances and carries connected equipment through outages.
Buy it to protect a small network cabinet with a shallow lithium-ion unit that offers hot swap batteries and data line protection. Listed runtime is very short and the load behind that figure is not stated, so plan on bridging brief outages, not running through long ones.
Who it's for
A small office with a short-depth network cabinet gets battery backup without giving up much rack space. A server room that must run through a long blackout needs a larger unit.
Pros and cons
- One rack unit tall, short depth
- Lithium-ion battery with long service life
- Hot swap batteries
- Built-in data line protection
- Short listed runtime
- Load behind the runtime figure not listed
- Four outlets only
- Modest output for larger servers
Performance notes
Runtime depends on the connected load: the lithium-ion pack stores a fixed amount of energy, so lighter loads stretch it and heavier ones shorten it. During a disturbance or outage the unit supplies the outlets from the battery, while built-in data line protection covers connected network lines.
