BATTERY POWER

If the utility power fails, the UPS can provide power to the connected equipment from its internal battery for a finite period. The UPS sounds an alarm—four beeps every 30 seconds—while operating on battery power. The alarm stops when the UPS returns to online operation.

On Battery

Battery Charge

Overload

Replace Battery

When the on battery power LED is lit the UPS is supplying battery power to the connected equipment.

The five-LED display on the right of the front panel shows the present charge of the UPS battery as a percentage of the battery capacity. When all five LEDs are lit, the battery is fully charged. The LEDs ex- tinguish, from top to bottom, as the battery capacity diminishes. Refer to the figure at left for the battery capacity threshold (values are not listed on the UPS).

As a low battery warning, any LEDs illuminated (for the given capac- ity) flash and the UPS beeps. The low battery warning default setting can be changed from the rear panel or through the optional Power- Chute software. Refer to Default Settings below for details.

The UPS emits a sustained alarm tone and the LED illuminates when an overload condition occurs. Refer to Troubleshooting in this manual.

Failure of a battery self-test causes the UPS to emit short beeps for one minute and the replace battery LED illuminates. Refer to Trouble- shooting in this manual.

SHUTDOWN MODE (VIA SOFTWARE OR AN ACCESSORY)

In shutdown mode, the UPS stops supplying power to the connected equipment, waiting for the re- turn of utility power. If there is no utility power present, external devices (such as servers) connected to the computer interface or the accessory slot can command the UPS to shut down. This normally is done to preserve battery capacity after the shutdown of protected servers. The UPS scrolls the front panel LEDs sequentially in shutdown mode.

1400VA XL, SURT48XLBP, SL 300TFX, 120VAC, SL-300TFX specifications

American Power Conversion (APC) has long been renowned for its commitment to providing reliable power protection solutions. One of their well-regarded offerings is the APC 750VA, 100VAC Uninterruptible Power Supply (UPS). This model is designed to safeguard sensitive electronic equipment from power disturbances while ensuring continuous operation during outages.

The APC 750VA, 100VAC UPS is built to accommodate the power requirements of small networks, home office setups, and personal use. With a 750VA power capacity, it provides essential support for a variety of devices, including computers, networking equipment, and peripherals, ensuring that they remain operational during unexpected power interruptions.

One of the standout features of this APC model is its sine wave output. Unlike traditional modified sine wave outputs, sine wave technology delivers a smoother waveform, which is less stressful on connected devices, improving their longevity and performance. The UPS also includes automatic voltage regulation (AVR) that stabilizes voltage levels by correcting minor power fluctuations without switching to battery mode, thereby extending battery life and reducing unnecessary wear.

The unit also boasts several communication options. It features USB and serial ports that allow for easy connection to management software, enabling users to monitor power usage and battery health. The built-in alarm systems similarly notify users of power disturbances or battery failure, providing critical alerts that facilitate timely interventions.

Another notable characteristic of the APC 750VA UPS is its compact form factor, making it easy to position within home or office environments without consuming much space. The design is also user-friendly, featuring a clear LED display that shows battery status, load level, and overall health status at a glance.

In terms of battery characteristics, the UPS uses sealed lead-acid batteries that are user-replaceable, simplifying maintenance and ensuring that the system continues to operate effectively over the years. The battery runtime is adjustable, allowing users to choose between higher performance for critical devices or extended backup time for non-essential devices.

Overall, the APC 750VA, 100VAC UPS is a versatile and robust power protection solution, blending innovative technology with practical design elements to meet the diverse needs of users in a variety of settings. With its reliable performance, advanced features, and user-friendly interface, it has become an essential component for ensuring continuous power availability and protecting valuable electronics.
