Industrial UPSs are regarded as fully customized power supply systems for rugged environments and designed particularly to safeguard critical loads in industrial applications where voltage transients, created by degraded mains supply, can seriously damage both UPS and the critical load.Industrial UPS Systems are fully flexible and customizable and designed for active–on line installation between the power source, by-pass source and critical load where the inverter delivers regulated AC voltage and frequency to the load and rectifier delivers regulated DC voltage / current to the DC load at all times without interruption.
Protects against power surges and provides battery backup in the event of a power outage. AC power passes through the unit under normal conditions and switches to battery mode when a power failure is detected.
A standby UPS resorts to battery backup power in the event of common power problems such as a blackout, voltage sag, or voltage surge. When incoming utility power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run connected equipment. These models are designed for consumer electronics, entry-level computers, POS systems, security systems, and other basic electronic equipment.
In addition to battery backup, line-interactive UPS provide conditioned power, eliminating voltage fluctuations. AC power passes through a voltage regulator, which corrects low and high voltages as needed, and switches to battery backup mode when a power failure is detected.
With line-interactive UPS, the inverter becomes part of the output and is always on. The inverter can operate in reverse to charge the battery while AC input is normal and switch to battery power when input fails. Internal components provide filtering and voltage regulation that raises and lowers utility power to the level needed by the connected equipment. In some cases, line-interactive UPS systems rely on the battery to condition power so it may use the battery more frequently than online UPS systems that condition power through the double-conversion process.When AC input power fails, the unit’s transfer switch opens and the power flows from the battery to the UPS output. With the inverter always on and connected to the output, line-interactive UPS provides additional filtering and yields reduced switching transients when compared to a standby UPS. Line-interactive UPS systems are typically used in rackmount applications below 5000VA.
Incoming AC power is converted to direct current (DC) and then back to high-quality AC power, free from voltage fluctuations and other distortions common in grid power. Online UPS systems also include a high-efficiency ECO mode, which automatically suspends or resumes double conversion depending on the quality of input power.
Double conversion UPS modules provide uninterrupted power to critical loads. They do this by filtering and converting incoming utility power to DC power, then converting the DC power to a perfect AC output from the inverter. The inverter is also supported by a DC source that may include batteries (or flywheels). Through this process, a true double-online conversion UPS protects the critical load from any transient or voltage anomaly including surges, sags, swells and line drops.
