Total Protection with Online Double Conversion
All N1C L-Series UPS systems are Online Double Conversion. What’s that mean? Simply put, it means they protect against all nine power problems.
It does this by isolating the connected load from the incoming AC power. The incoming “wall” power, is converted to DC power, then converted back to AC before reaching the UPS outlets. This keeps your load isolated and protected with no transfer time during an outage, and keeps the power steady with a pure sine wave and consistent voltage, perfect for the most sensitive equipment!
See below for a better understanding of the 9 power problems and different types of UPS topology!
A total loss of utility power.
Short-term high voltage (>110% of normal)
Short-term low voltage (a dip in AC power)
Reduced line voltage for an extended period (minutes to days). Common in summer with air conditioners running.
Increased line voltage for an extended period (minutes to days).
High power frequency wave usually from radio frequency interference or electromagnetic interference.
Loss of stability in the power’s normal frequency (50-60Hz).
Instantaneous under-voltage in the range of nanoseconds.
Distortion in the normal power wave, generally transmitted by unequal power loads.
Online double conversion UPS systems offer the most protection by isolating equipment from utility power. Power is converted from AC to DC and then back to AC, delivering a pure sine wave and zero transfer time. Most N1 Critical UPS systems are online double conversion, which is by far the best for mission-critical applications as it protects from all 9 power problems.
Line-interactive systems regulate voltage of the utility power before allowing it to pass to connected equipment. Line-interactive UPS devices protect against five power problems: power failures, surges and sags, as well as over and under voltage conditions. Often priced between Online Conversion and Standby UPS systems, they are popular choices in server, network and communication closets, and general IT enclosures.
Standby systems are the most basic of the UPS topologies. Power is filtered to minimize surges, but may have a short delay before switching to battery power during an outage. They are used mostly for protecting non-critical equipment, such as desktop PCs and home/office equipment. Standby UPS systems will protect against 3 of 9 power problems — failures, surges and sags.
Ferroresonant UPS is an older, but still effective, system that is similar to the Line-Interactive topology. These UPS systems use a ferroresonant transformer to condition incoming power and hold energy long enough to keep connected equipment running as the device switches from line to battery power. Ferroresonant UPS systems protect against 8 out of 9 power problems (not frequency variation).
