Find robust and reliable power supplies and DC-UPS solutions for critical infrastructure projects in the electrical grid.
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
With UPS installations in plants and substations, you can guard against downtime throughout your entire infrastructure. Avoid the irony of a power plant without power with uninterruptible power supplies to ensure the continuity of the utility's supply and minimize disruptions.
The static uninterruptible power supply (SUPS) basically consists of four major blocks. They are the battery rectifier/charger, battery bank, inverter and the transfer switch. The rectifier/charger receives the normal alternating current (AC) power supply, provides direct current (DC) power to the inverter, and charges the battery.
