Double-conversion UPS

The APC Smart-UPS SRT 1500VA is an online double-conversion uninterruptible power supply rated at 1.35 kW and 1500 VA. It uses sealed lead-acid batteries and provides six NEMA 5-15 output receptacles for connected equipment. A built-in circuit breaker protects against overloads.

Network-managed environments

This unit suits server rooms and network closets that need pure sine-wave output and remote monitoring through USB, RS-232 or the RJ-45 management port. It also includes an emergency power-off connector. Buyers who only need basic desktop backup without network management should look at simpler line-interactive models.

5-minute runtime at full load

At 100 % load the UPS delivers up to 5 minutes of battery runtime, extending to 13 minutes at half load. Recharging the batteries takes approximately 3 hours. Efficiency reaches 91 % at full load, 90.5 % at 75 %, 90.2 % at 50 % and 86.6 % at 25 % load.

Questions about this item

How do I connect the USB management cable and what step is often missed?

Plug the supplied 6 ft USB cable into the UPS USB port and the server, then install the APC management software so the UPS can trigger graceful shutdowns; skipping the software install leaves the link inactive.

When will the internal lead-acid battery need replacement and what is the procedure?

The sealed, maintenance-free battery typically lasts 3-5 years; when runtime drops below the 5 min full-load or 13 min half-load figures, power down the load, open the front panel, disconnect the old pack, and install a new APC RBC cartridge.

At what load does the 50 dBA fan noise become constant during sustained operation?

The 50 dBA sound emission is measured at full 1500 VA load; under continuous half-load the fan runs slower and is quieter, while at 100 % load it stays at the rated 50 dBA.
