PROBLEM AND POSSIBLE

CAUSE

SOLUTION

UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS

UPS input circuit breaker tripped.

Very high, low, or distorted line voltage. Inexpensive fuel powered generators can distort the voltage.

Reduce the load on the UPS by unplugging equipment and resetting the circuit breaker (on the back of UPS) by pressing the plunger in.

Move the UPS to a different outlet on a different circuit. Test the input voltage with the utility voltage display (see below). If acceptable to the connected equipment, reduce the UPS sensitivity.

BATTERY CHARGE AND BATTERY LOAD LEDS FLASH SIMULTANEOUSLY

The internal temperature of the UPS has exceeded the allowable threshold for safe operation.

Check that the room temperature is within the specified limits for opera- tion.

Check that the UPS is properly installed allowing for adequate ventila- tion.

Allow the UPS to cool down. Restart the UPS. If the problem continues contact APC at, www.apc.com/support.

DIAGNOSTIC UTILITY VOLTAGE FEATURE

Utility Voltage

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power.

Press and hold the button to view the utility voltage bar graph dis-

play. After a few seconds the five-LED, Battery Charge, , display on the right of the front panel shows the utility input voltage.

Refer to the figure at left for the voltage reading (values are not listed on the UPS).

The display indicates the voltage is between the displayed value on the list and the next higher value.

Three LEDs light, indicating utility voltage within the normal range.

If no LEDs are lit and the UPS is plugged into a working utility power outlet, the line voltage is extremely low.

If all five LEDs are lit, the line voltage is extremely high and should be checked by an electrician.

The UPS starts a self-test as part of this procedure. The self-test does not affect the voltage display.

100VAC, 750VA 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.
