Ideal for servers and network gear

The Smart-UPS SMT750C delivers 750 VA and 500 watts of battery backup power to protect servers, switches and routers from outages, spikes and surges. Six NEMA 5-15R outlets provide battery and surge protection for critical loads, while the 120 V input range of 82 to 144 V handles unstable mains. Automatic green mode maximises operating efficiency.

Smart-Slot and USB enable cloud monitoring

A Smart-Slot and USB port connect the UPS to APC SmartConnect for remote cloud monitoring from any internet device. The service delivers proactive advice and life-cycle recommendations to extend battery life. Intelligent battery management uses temperature-compensated charging to further prolong runtime. Alarms signal on-battery status and low battery with configurable delays.

Verify 120 V supply and outlet count

Confirm the site provides 120 V mains with a NEMA 5-15P receptacle for the input plug. Ensure six outlets are sufficient for the protected equipment and that the 4.6 minute runtime at full load or 15.8 minutes at half load meets the required shutdown window. The replaceable RBC48 battery requires three hours to recharge after a discharge event.

Questions about this item

How long does the RBC48 battery last before it needs replacement?

The sealed lead-acid RBC48 battery typically lasts three to five years; the UPS provides a distinctive low-battery alarm and configurable delays to warn you when replacement is due.

What is the maximum runtime at full 500 W load before the battery depletes?

At full 500 W load the SMT750C runs for 4.6 minutes; at half load it extends to 15.8 minutes, so sustained heavy draw is the first limit you hit.

How much heat and noise does the unit produce during all-day operation?

Automatic green mode maximises efficiency, and temperature-compensated charging keeps the battery cool, so heat and fan noise stay low during continuous use.
