The Overload LED is illuminated and the UPS emits a sustained alarm tone

 

 

The UPS is overloaded.

The connected equipment exceeds the specified “maximum load” as defined

 

in Specifications on the APC Web site, www.apc.com.

 

The alarm remains on until the overload is removed. Disconnect nonessential

 

equipment from the UPS to eliminate the overload condition.

 

The UPS continues to supply power as long as it is online and the circuit

 

breaker does not trip; the UPS will not provide power from batteries in the

 

event of a utility voltage interruption.

SUA3000, SUA2200 specifications

The APC SUA2200 and SUA3000 are well-regarded uninterruptible power supplies (UPS) from Schneider Electric, designed to provide reliable power backup and protection for critical electronic equipment. These models cater to a range of applications, from small business environments to larger enterprise setups, ensuring that devices remain operational during power outages or fluctuations.

Starting with the APC SUA2200, it boasts a capacity of 2200 VA / 1980 W, making it suitable for powering essential devices such as network equipment, servers, and workstations. One of its standout features is the Pure Sine Wave output, which ensures that sensitive electronics receive clean power, thus preventing potential damage or operational issues. Additionally, the SUA2200 comes equipped with Automatic Voltage Regulation (AVR) technology, which stabilizes voltage levels and protects connected equipment from surges and sags.

Moving to the APC SUA3000, this model offers even greater capacity, rated at 3000 VA / 2700 W, making it ideal for larger deployments where more power is needed. Similar to the SUA2200, it also features Pure Sine Wave output and AVR technology for enhanced protection. The SUA3000 is designed with a graphical LCD interface that provides real-time information on power status, battery condition, and load levels, allowing users to monitor their UPS system with ease.

Both models utilize high-frequency technology, which results in a smaller and more efficient form factor compared to traditional line frequency UPS systems. They also feature multiple surge-protected outlets, enabling users to connect various devices simultaneously. The SmartSlot feature allows for additional management options with the installation of network management cards, enabling remote monitoring and management capabilities.

The battery management system incorporated into both models extends battery life and ensures efficient charging cycles. Users can expect longer runtimes and the ability to replace batteries easily when needed. Compatibility with APC's PowerChute software also enhances performance by providing advanced management capabilities and system monitoring.

In summary, the APC SUA2200 and SUA3000 serve as robust solutions for organizations seeking reliable power protection. Their combination of high capacity, advanced technologies like Pure Sine Wave output and AVR, along with user-friendly interfaces, make them ideal choices for safeguarding critical electronic equipment against power disruptions. These UPS systems not only ensure uninterrupted power supply but also foster longevity and operational efficiency in power management.
