APC Smart-UPS 1500VA Lithium Ion UPS, SMTL1500RM3UCNC, Short Depth, Pure Sine Wave Rack Mount UPS with Network Card

The APC Smart-UPS 1500VA Lithium Ion UPS, with its pure sine wave output, is a strong contender for those needing reliable power backup, especially in settings like small to medium server rooms or for critical network equipment. The 1500VA / 1350W capacity is robust enough to support multiple devices, with six available outlets providing good flexibility for connecting essential gear.

One of the standout features is the multi-function LCD console, which keeps users informed about the UPS status, including power conditions and battery health. The included Network Management Card allows for remote monitoring, making it easier to manage power needs without being physically present. Additionally, the 5-year warranty shows the manufacturer's confidence in the product's durability and performance.

The 3U rackmount design may not be suitable for everyone, particularly those who prefer a more compact form factor for home use. While lithium-ion batteries offer longer life and reduced maintenance compared to traditional lead-acid batteries, they can come at a higher initial cost. Users should consider whether the advanced features like SmartConnect, which offers a six-month free trial for remote management and notifications, are necessary for their specific use case.

Liebert GXT4 UPS w/Network Card - 6000VA/4800W 208V/120V, Online Double Conversion Rack Mount/Tower UPS, Uninterruptible Power Supply, Sine Wave, AVR, Battery Backup(GXT4-6000RT208)

The Liebert GXT4 UPS with a Network Card offers substantial power protection with a capacity of 6000VA/4800W, making it suitable for critical equipment that requires uninterrupted power. One of its main strengths is the on-line double-conversion technology that conditions power without relying on the battery, thereby extending the battery life. This UPS also features seamless transfer to battery power during outages, ensuring your equipment continues to run without interruption.

The included hot-swappable batteries provide up to 5 minutes of backup at full load, with the option to add extra battery cabinets for longer runtimes, which can be crucial during extended power outages. With four outlets, it has a decent number of connections for various devices. This model can be used as either a rack mount or tower, offering flexibility depending on your setup needs.

Additionally, the integrated communications card allows for remote monitoring and management, a useful feature for keeping an eye on power status through the Trellis power insight application or other platforms. However, it's important to note that this model is now obsolete, and the recommended replacement is the GXT5-6000MVRT4UXLN. For those who prefer up-to-date technology and support, considering the newer model might be beneficial. Its hefty weight and larger dimension could be a downside when considering ease of installation or space constraints. It’s a robust and reliable UPS ideal for environments where maintaining power without interruption is critical.

Buying Guide for the Best Sine Wave Ups

When choosing a sine-wave UPS (Uninterruptible Power Supply), it's important to understand the key specifications that will ensure you get the best fit for your needs. A sine-wave UPS provides a smooth and consistent power output, which is crucial for sensitive electronic equipment. By understanding the key specs, you can make an informed decision that will protect your devices and keep them running smoothly during power outages or fluctuations.
Power Capacity (VA/W)Power capacity, measured in Volt-Amperes (VA) or Watts (W), indicates the maximum load the UPS can handle. This is important because it determines how many and what type of devices you can connect to the UPS. For light usage, such as a single computer or small home office setup, a lower capacity (around 600-1000 VA) may suffice. For larger setups with multiple devices or more power-hungry equipment, you might need a higher capacity (1000-3000 VA or more). To pick the right one, calculate the total power consumption of all the devices you plan to connect and choose a UPS with a capacity that exceeds this total.
Battery RuntimeBattery runtime refers to how long the UPS can provide power to your devices during an outage. This is crucial for ensuring that you have enough time to save your work and safely shut down your equipment. Shorter runtimes (5-10 minutes) are suitable for brief outages or for giving you enough time to save your work. Longer runtimes (20 minutes or more) are better for areas with frequent or prolonged outages. To choose the right runtime, consider how long you need your devices to stay powered during an outage and select a UPS that meets or exceeds this requirement.
Waveform TypeThe waveform type indicates the shape of the electrical output. A pure sine wave is the best type, as it closely mimics the power from the grid and is suitable for all types of equipment, especially sensitive electronics like computers, servers, and audio/video equipment. Modified sine wave or square wave UPS units are less expensive but may not be suitable for sensitive devices. If you are using the UPS for high-end or sensitive electronics, always opt for a pure sine wave UPS to ensure compatibility and safety.
Transfer TimeTransfer time is the duration it takes for the UPS to switch from mains power to battery power during an outage. This is important because a shorter transfer time ensures that your devices experience minimal interruption. Transfer times can range from a few milliseconds to several milliseconds. For critical applications where even a brief interruption can cause issues, look for a UPS with a transfer time of 4 milliseconds or less. For less critical applications, a transfer time of up to 10 milliseconds may be acceptable.
Outlets and ConnectivityThe number and type of outlets on a UPS determine how many devices you can connect and what types of plugs are supported. This is important for ensuring that all your devices can be powered by the UPS. Some UPS units also offer USB ports and network management capabilities, which can be useful for monitoring and managing the UPS remotely. To choose the right UPS, count the number of devices you need to connect and ensure the UPS has enough outlets of the correct type. If you need remote management, look for models with the appropriate connectivity options.
Form Factor and SizeThe form factor and size of the UPS determine where you can place it and how much space it will occupy. This is important for ensuring that the UPS fits in your desired location, whether it's under a desk, in a server rack, or on a shelf. UPS units come in various sizes, from compact desktop models to larger tower or rack-mounted units. To pick the right one, measure the available space where you plan to place the UPS and choose a model that fits comfortably within those dimensions.
