Purpose and audience

The Tripp Lite SMART500RT1U is a line-interactive UPS rated at 500 VA and 300 W for 120 V environments. It delivers battery backup and surge protection for small network, telecom or digital-signage loads in a 1U rack or tower form factor.

Who it suits and who it does not

Six NEMA 5-15R outlets, USB, DB9 serial and an optional network management card slot make it a fit for administrators who need remote monitoring and safe shutdown software. Sites that require longer runtime at full load or higher wattage capacity should consider a larger unit.

The deciding specification

At full 300 W load the battery provides 3 minutes of runtime; at 150 W half load it extends to 14 minutes. Recharge to 90 % takes less than 12 hours and surge energy rating is 567 J.

Questions about this item

Is the 500 VA / 300 W rating sufficient for my router and switch stack?

The unit delivers 500 VA and 300 W; at full 300 W load it runs for 3 minutes, while at 150 W it provides 14 minutes, so size your load accordingly.

What does the 300 W output actually sustain during a blackout?

It maintains 120 V nominal output for 3 minutes at 300 W or 14 minutes at 150 W, giving time to save files and shut down safely.

Which management interfaces are built in and what does the optional card add?

USB HID, DB9 serial and an EPO port are standard; the optional SNMP/Web card enables 24/7 remote monitoring and control.
