Mirapath Blog: Top 8 things to look for in a UPS

So you need a new UPS system and you've already identified the Voltage and kW load requirements for your environment. How do you then decide which UPS to purchase and from which manufacturer?

Regardless of the size of UPS you are looking for, there are several factors below that can help you differentiate one UPS from another. Not all UPS systems are created equal even though their power ratings may be similar.

Let's start with number 1...

A Mirapath Success Story: Expend less energy and stay cool with containment.



A Fortune 1000 company headquartered in San Jose, CA was looking to reduce energy consumption in their 2,500+ sq. ft. data center while keeping their cooling requirements intact. Having already implemented blanking panels in their hot and cold aisle layout, the next logical step was a containment solution. With the lack of a containment solution in place, the hot air and cold air were allowed to mix, causing a decrease in air conditioning efficiency.

Overview

Liebert NX is a mid-sized, three-phase UPS system that delivers complete, centralized power protection for mission-critical systems. Designed to meet the high availability power needs of a wide variety of IT applications, the UPS combines compact size, advanced operating features and low cost of ownership.

Features and Benefits

The 120/208 Volt, three-phase, version of the Liebert NX is available in four sizes including 10, 15, 20 and 30 kVA capacities.

Flexibility:

  • Power communications available through a Relay Contact Card, OpenComms™ Web Card and MultiLink™ shutdown software.
  • Ultra-quiet performance with noise levels below 54dB allows greater latitude in where to place the unit.
  • Large and user-friendly LCD display provides operating information in twelve languages.
  • Up to three Liebert NX modules can be paralleled and a fourth added for redundancy without using a centralized controller or centralized static switch.
  • For safe and convenient servicing of the UPS, the unit includes a built-in maintenance bypass. Optional wrap-around maintenance bypass is also available.
  • Easy servicing due to front accessibility of critical components, self-diagnostics and various monitoring options.

Higher Availability:

  • True on-line double conversion technology corrects all types of power fluctuations.
  • Advanced inverter control technology provides the highest output power quality.
  • Redundant power supply cords, redundant cooling fans and highly efficient cooling of critical components.
  • Minimized transfer to battery, reducing the number of charging and discharging cycles, due to the wider input voltage window of +10 to -20% and a frequency tolerance of 40Hz to 72Hz.
  • Compatibility with dual bus synchronization system enables you to transfer the load to an alternate power source for maintenance activities.
  • High overload protection handles 125% for 10 minutes, 150% for one minute and a 1000% overload for 10 milliseconds.
  • An intelligent battery management algorithm monitors the battery to detect any premature battery failure.

Lowest Total Cost Of Ownership:

  • Temperature-compensated battery charging extends battery life.
  • Highest possible input power factor for maximum efficiency.
  • Adjustable power walk-in from 5 seconds to 30 seconds, along with reduced input current distortion and power factor correction, also enables you to save money by reducing back-up generator sizing requirements.
  • The unit's compact footprint requires less floor space, leaving you with more room for other equipment.

Ideally Suited For:

  • Server rooms and mid-sized data centers
  • Network components including critical routers and switches
  • Networks (LAN and WAN)
  • Industrial process and motion automation for mid-sized plants
  • Medical diagnostic/imaging equipment
