Basic Operation continued

MUTE/TEST Button:

Silence the UPS On-Battery Alarm: Press and hold this button to silence the UPS on-battery alarm, a series of short beeps followed by a brief pause that is activated when the UPS is providing AC power from battery. Note: When the battery is nearly depleted, the low battery alarm—a continuous beep that cannot be silenced—will warn to shut down connected equipment immediately.

Run a Self-Test: To run a self-test, leave connected equipment on.

With the UPS plugged in and ON, press and hold the button until the

UPS beeps (about 2 seconds) then release it.

Self-Test Results: All LEDs will be lit and the UPS will emit several short beeps as it momentarily switches to battery to test charge and load capacity. The test will last up to 10 seconds. If the inverter is overloaded, the “ ” LED will stay lit and the UPS will continue to beep after the test; if this happens, remove some of the load from the “UPS/Surge” outlets and run the self-test again. If the batteries are weak, the “ ” LED will stay lit and the UPS will continue to beep after the test. If this happens, let the UPS charge its batteries for 12 hours and repeat the test. If the condition persists, contact Tripp Lite for service. CAUTION: Do not unplug the UPS to test its batteries. This will remove safe electrical grounding and may introduce a damaging surge into network connections.

All Indicator Light descriptions apply when the UPS is plugged into an AC outlet and turned on.

LINE POWER: This green light will illuminate whenever the UPS is ON and receiving normal AC line power.

BATTERY POWER: This yellow light will illuminate when the UPS is providing equipment with battery power.

REPLACE BATTERY: This red light will illuminate continuously after the UPS runs a self-test to indicate that the battery is weak. If it remains lit after allowing the UPS to charge for twelve hours and running a second self-test, contact Tripp Lite for service.

OVERLOAD: This red light will illuminate continuously to indicate that the UPS is overloaded when the UPS is providing power from battery or after the UPS runs a self-test. If it lights up, immediately remove some of the equipment connected to the “UPS/Surge” outlets and run a self-test. Large overloads may cause the UPS to shut down.

SMART550USB specifications

The Tripp Lite SMART550USB is an essential uninterruptible power supply (UPS) that offers reliable battery backup and surge protection for sensitive electronic devices. With a power capacity of 550VA/300W, this UPS model is designed to keep equipment such as computers, networking devices, and home entertainment systems operational during power outages and fluctuations. The SMART550USB strikes a perfect balance between performance and affordability, making it an attractive choice for both home and small office environments.

One of the standout features of the SMART550USB is its sine wave output, which provides clean and stable power to connected devices. Unlike modified sine wave UPS systems, true sine wave output helps protect sensitive electronics from potential damage caused by electrical disturbances. This feature is particularly important for devices like desktop computers, printers, and audio/video equipment that require a steady, high-quality power supply to function properly.

The SMART550USB is also equipped with multiple outlets, allowing it to accommodate various devices simultaneously. The unit features a total of eight NEMA 5-15R outlets, with four outlets providing battery backup and surge protection, while the other four offer surge protection only. This configuration enables users to connect critical devices to the battery backup while protecting non-essential equipment from power surges.

Another notable characteristic of the SMART550USB is its user-friendly interface, which includes an LCD display that provides real-time information on battery status, load capacity, and estimated runtime. This allows users to monitor the UPS's performance at a glance, making it easy to manage power needs effectively.

For added convenience, the SMART550USB comes with USB and serial communication ports, enabling automatic shutdown and monitoring through compatible software. Users can connect the UPS to a computer to receive alerts regarding power conditions and manage settings through Tripp Lite's PowerAlert software.

The SMART550USB also features advanced technologies for battery management and protection. Its built-in automatic voltage regulation (AVR) helps maintain consistent voltage levels, reducing wear and extending battery life. Additionally, the unit includes an array of safety features, such as overload protection, short-circuit protection, and battery fault tolerance, ensuring that both the UPS and connected devices remain safe during operation.

In summary, the Tripp Lite SMART550USB is a versatile and dependable UPS solution, perfect for safeguarding critical electronic devices from power interruptions and surges. With its sine wave output, multiple outlets, user-friendly display, and advanced battery management, this UPS is an excellent choice for anyone looking to enhance power reliability in their home or office.
