![]() ![]() BBP-AR-1000-PSW-ONL we see that it is rated at 1 KVA (1000 VA) / 900 Watts, so 900 / 1000 = 0.9 = 90% efficiency.ĭon't believe us about power savings? Take two clamp meters and measure the amperage going from the wall receptacle to the battery backup UPS and then from the battery backup UPS to your equipment. So for a battery backup UPS rated at 1.5 kVA (1,500 VA) / 900 Watts, use 900 / 1500 = 0.6 = 60% efficiency. ![]() Divide the watt rating of the battery backup UPS by the VA or kVA rating. Is the power factor not listed? No problem. Upgrading an older battery backup UPS to a newer, more efficient model will result in long term energy savings. Using a cheaper battery backup UPS with less than 90% efficiency will cost you more in energy to operate. models come with ECO mode which allows up to 99% efficiency. For example, a quality battery backup UPS will be 90% efficient or more (0.9 power factor). Efficiency is measured by how much power is consumed by the battery backup UPS. No Uninterruptible Power Supply (No Protection) During Power Eventģ. Alternatively when they do fail, most consumers believe the batteries failed because the unit "worked" for a while and just toss the low cost battery backup UPS out and purchase a new one. This allows manufacturers of cheaper systems to sell incompatible low cost units as the majority of them will never actually be tested with a power failure or unplug test. Older electronics may continue to function on sub-par wave forms provided by cheap UPS systems when on backup power. Any low cost, cheap battery backup UPS will bypass power during normal operation, so you will never know there is a compatibility problem until you have a power outage or conduct an unplug test. Newer electronics and energy efficient electronics such as those with Active PFC or an Energy Star 5.0 or higher rating typically require pure sine wave to function correctly. ![]() What does pure sine wave mean? When you plug your electronics into a wall socket, you get pure sine wave power. double conversion unit at its Moon Rock Analysis lab in Huntsville, Alabama (see below picture).Ģ. This is why NASA uses a Battery Backup Power, Inc. Their output power is equivalent or better than what comes out of a wall socket (utility power), so any electrical device will work with this type of UPS. These units are used to backup and filter out power problems for critical electronics and ultra sensitive electronics. There is also additional electrical noise filtration, voltage regulation, frequency correction, and other power conditioning that occurs depending on the unit purchased. This separates power issues at the input source (grid power, generator, etc.) from the output of the UPS providing clean, continuous power no matter what happens on the input side. They typically continuously convert the input AC power to DC power (for the batteries), then take the DC power from the batteries and convert it back to AC power for the attached electronics. Double conversion (also referred to as online) uninterruptible power supplies have absolutely no delay in switching to backup power or filtering out electrical problems because they are always online. They are double conversion (no transfer delay)ġ.Quality systems have the following features: View Available Products By Clicking Here. ![]() only sells quality battery backup UPS (uninterruptible power supply) systems. ![]()
