CAUSE

 

 

 

THE OVERLOAD LED IS LIT AND THE UPS EMITS A SUSTAINED ALARM TONE

The UPS is overloaded.

 

 

The connected equipment exceeds the specified “maximum load” as de-

 

 

 

fined in Specifications at the APC web site, www.apc.com.

 

 

 

The alarm remains on until the overload is removed. Disconnect nonessen-

 

 

 

tial equipment from the UPS to eliminate the overload.

 

 

 

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.

 

 

 

If a continuous overload occurs while the UPS is on battery, the unit turns

 

 

 

off output in order to protect the UPS from possible damage.

1000, 750VA specifications

American Power Conversion (APC) is a leading name in the field of uninterruptible power supplies (UPS), offering a range of products designed to ensure power reliability for various applications. Among its notable models are the APC 1000, 1050, 1100, and 1400 VA units. Each of these models comes packed with features and technologies aimed at protecting sensitive electronic equipment from power disruptions.

The APC 1000 VA model is designed to cater to small server rooms, workstations, and point-of-sale systems. With a capacity of 1000 VA, this model can support several devices simultaneously, providing robust battery backup and surge protection. Its Automatic Voltage Regulation (AVR) helps maintain a consistent voltage level, safeguarding connected equipment from overvoltages and undervoltages. The unit is equipped with an LCD interface that displays real-time data regarding battery status, load levels, and estimated runtime.

The APC 1050 VA is a slightly upgraded version that offers a higher power capacity suitable for more demanding applications. This unit features advanced battery management technology, enhancing battery performance and prolonging its lifespan. With an extended runtime capability, the APC 1050 is ideal for critical systems that require longer power backup in case of outages. The hot-swappable batteries allow for easy maintenance without interrupting the power supply.

Moving up the range, the APC 1100 VA model provides additional features like built-in PowerChute software, which allows users to manage UPS settings and safely shut down systems during prolonged outages. This model is renowned for its compact design and energy efficiency, making it an excellent choice for both home office setups and small business environments.

Lastly, the APC 1400 VA model offers robust performance tailored for larger systems or more extensive networks. It comes with additional outlets and improved power distribution options, ensuring that multiple high-draw devices can be supported at once. This model is particularly beneficial for IT environments where equipment uptime is paramount.

In summary, APC’s 1000, 1050, 1100, and 1400 VA UPS models are engineered with advanced technologies such as AVR, enhanced battery management, and comprehensive monitoring systems. These features help provide reliable power protection and performance, making them essential components for anyone looking to safeguard their electronic investments against power fluctuations and outages.
