Uninterruptible Power Supplies (UPS)On sites where there is a known problem with temporary power outages or brownouts, batteryback-up devices should be installed. Most battery back-up devices are known asUninterruptible Power Supplies (UPS). When power to equipment is momentarily lost, theUPS devices draw power from an internal ‘gel cell’ battery to keep the equipment operating.The length of time these devices power the POS system is dependent on the capacity of theinternal batteries. Many sizes are available, but typically the units installed on POSequipment keep the computers powered for about 20 minutes. This will give servers andmanagers time to settle bills, print checks and power down the system in an orderly fashion.CRS recommends POWERVAR Security One Series Uninterruptible PowerSupplies, the most advanced, line-interactive, true sine wave UPM productsavailable for your application.
