Uninterruptible Power Supplies (UPSs) – Protection for your Business Phone System

UPSs (uninterruptible power supplies, or “battery back-ups”) are great in protecting your business’ line of communication during major disasters, especially like the major storms and floods we’ve experienced in Houston lately. UPS helps ensure that your system keeps on running in an event of a power failure for at least 1-2 hours no matter the size of your business phone system. There are many different types of designs in use by major UPS manufacturers. Let us know if you have additional questions, or have been in an unfortunate accident where you are in need of a replacement business phone system or UPS.

UPSs can first be broken down into system types:

  • Stand-by — A very simple design that affects power only when either a lag/brownout occurs below, or a spike/surge occurs above, a certain threshold. When either occurs, the unit trips — i.e., goes into battery mode. This “cleans” the voltage and helps to keep any load safe. Industry average “trip” times are 2–8 ms. No other filtration of AC power is performed.
  • Line interactive — Constantly monitors inbound voltages, and uses special circuitry to boost low voltages and clamp high voltages without having to use the batteries. Indeed, the batteries are used only if the input voltage drops below acceptable levels (typically about 12% below normal), goes out completely or rises to dangerous levels (typically about 14% above normal) at which components will be damaged if line voltage is not removed. Industry average transfer time is 1–3 ms. (If voltage stays within its normal window, this unit continues to pass voltage, unaltered, from the wall.)
  • On-line (or full on-line) — Constantly filters the power and performs a function known s double conversion (AC to DC to AC). This assures that the load — in this case, phone equipment — will receive not only uninterrupted, true sine wave output but also the cleanest, steadiest power possible throughout any foreseeable power disruptions or voltage irregularities. According to industry specs, it is not unusual for these types of units to be able to regulate utility power, even when it drops to 27% below or rises to 33% above normal, all without using their batteries.

If you’ve experienced any flooding or lightning damage on your phone system, please don’t hesitate to call us at (281) 364-3710 we offer free consultation at no obligation.  Stay safe out there.
