Uninterruptible Power Supplies (UPS) For Datacentres
What do you look for in a datacentre UPS? Here is a short checklist for datacentre managers considering an uninterruptible power supply and UPS supplier for their applications:
1. Energy Consumption and Cooling
A high on-line operating efficiency of 93% or greater. This will result in less heat and noise being induced into the load area and place less demands on local air conditioning. A UPS at this level will comply with the European Commission Code of Conduct on Efficiency for Uninterruptible Power Supplies.
A high input power factor of 0.95 or greater to optimise the usage of mains power drawn.
The above two aspects - efficiency and power consumption - are generally the two of primary concern when it comes to any new capital investment.
2. Impact On The Local Electrical Environment
A low Total Harmonic Distortion (THDi) of 3% or less to reduce the impact on other systems connected to the same mains power supply. Compliance to G5/4 in the UK can be a prerequisite for new builds and is good practice when upgrading a legacy installation.
A low THDV to ensure load power supplies are not stressed by a poor UPS output supply. The quality of the output from a UPS is important to prevent power supply burn-out and early failures.
3. Impact On The Physical Environment.
A reduced physical footprint and weight (giving a high density) to reduce logistics related CO² emissions and the need for additional infrastructure investment.
Easy access to controls and terminals, in an ergonomic design.Where space is a premium there is not always the oppportunity to remove a piece of equipment once in situ without disturbing the installation. Easy front or top-level access assists maintenancne work and introduces less physical problems when access is required.
4. Use of Microprocessor Intelligence and State-of-the-art Electronics
- High frequency switching inverters with low noise outputs.
- A low component count to improve operating MTBF and MTTR figures.
- A reduced component count to improve reliability and reduce field service requirements visits.
- With predictive self-test routines to give advanced warning of pending problems - battery failure.
- Enhanced remote service diagnostics to reduce field engineer visits and ensure the right spares are sent to site.
5. Consumables management
- Long life maintenance free consumables - fans.
- A charge blocking feature to reduce charging current consumption.
- Temperature compensated and dual level charging with a low AC ripple.
- Intelligent battery management to reduce battery usage using stored energy for short duration ride through.
6. The Lowest Possible Total Cost of Ownership (TCO) and Maximum Resilience
- Readily available service assistance and support.
- Competitively priced product, easily available to market.
- Competitively priced and easy to access maintenance facilities.
- Quick to install and commission with competitively priced installation services.
- High reliability, resilient configurations and uptime to support business continuity expectations.
- Low running and maintenance costs with minimal maintenance requirements in terms of site visits, facility for remote diagnostics and advanced management of consumable items.
