Our UPS Systems also known as a battery backup systems, provides backup power when your regular power source fails or voltage drops to an unacceptable level. A uninterruptible power supply allows for the safe, orderly shutdown of a computer and connected equipment. The size and design of a uninterruptible power supply determine how long it will supply power. A double-conversion (online) UPS provides consistent, clean, and near perfect power regardless of the condition of incoming power. This uninterruptible power supply converts incoming AC power to DC, and then back to AC. Uninterruptible power supplies with this technology operate on isolated DC power 100 percent of the time and have a zero transfer time because they never need to switch to DC power. Double-conversion UPS systems are designed to protect mission-critical IT equipment, data center installations, high-end servers, large telecom installations and storage applications, and advanced network equipment from damage caused by a power blackout, voltage sag, voltage surge, over voltage, voltage spike, frequency noise, frequency variation, or harmonic distortion. PLC Technologies is a leading UPS distributor for APC, Delta Electronics, Eaton and Meissner uninterruptible power supplies.
