APC Smart UPS X Rack/Tower 750VA

Product Description

The APC Smart-UPS SMX750i from Specialist Power Systems is an intelligent and efficient network power protection from entry level to scaleable runtime. Ideal UPS for servers, point-of-sale, routers, switches, hubs and other network devices.

Cold-start capable provides temporary battery power when the utility power is out.
Energy meter provides actual kilowatt hours of usage for energy conscious users.
Green mode is APC’s patent-pending operating mode that bypasses unused electrical components in good power conditions to achieve very high operating efficiency without sacrificing any protection.
High online efficiency reduces utility costs and generates less heat.
Intuitive LCD interface provides clear and accurate information with the ability to configure the UPS locally with easy to use navigation keys.
Predictive replace battery date dynamically provides the month and year when battery replacement is recommended to aide in long term maintenance planning.
Pure sine wave output on battery simulates utility power to provide the highest degree of compatibility for active PFC (power factor corrected) servers and sensitive electronics.
SmartConnect is an innovative, easy to use remote monitoring feature that provides automatic notifications, firmware updates, and advanced support services.
Temperature-compensated battery charging prolongs battery life by regulating the charge voltage according to battery temperature.

  • Audible alarms provide notification of changing utility power and UPS conditions.
  • Serial connectivity provides management of the UPS via a serial port.
  • USB connectivity provides management of the UPS via a USB port (not available on all models).
  • LED status indicators allow the user to quickly understand the unit and power status with clear visual indicators.
  • Network manageable provides remote power management of the UPS over the network.


  • Automatic restart of loads after UPS shutdown which automatically starts up the connected equipment upon the return of utility power.
  • Temperature-compensated battery charging prolongs the battery life by regulating the charge voltage according to the battery temperature.
  • Power conditioning protects connected loads from surges, spikes, lightning, and other power disturbances.
  • Intelligent battery management maximizes battery performance, life, and reliability through intelligent, precision charging.
  • Disconnected battery notification warns when a battery is not available to provide backup power.
  • Boost and Trim Automatic Voltage Regulation (AVR) gives higher application availability by correcting low and high voltage conditions without using the battery (not available on all models).
  • Periodic battery self-test ensures early detection of a battery that needs to be replaced.


  • Adjustable voltage sensitivity provides the ability to adapt the UPS for optimal performance in specific power environments or generator applications.
  • Adjustable voltage-transfer points maximizes useful battery life by widening the input voltage window or tightening the output voltage regulation.


  • Battery failure notification provides an early-warning fault analysis on batteries enabling timely preventive maintenance
  • Hot-swappable batteries ensures clean, uninterrupted power to protected equipment while batteries are being replaced
  • Predictive failure notification provides an early-warning fault analysis ensuring proactive component replacement.
  • Resettable circuit breakers enable a quick recovery from overload events.
  • User-replaceable batteries increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
