Explaining the benefits of online double conversion technology.

Achieve a cleaner, more consistent signal
with double conversion UPS

 

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.

 

Line Interactive vs Online Double Conversion

UPS Efficiency

 

Line interactive UPS modules are directly connected to the incoming AC power supply. They have the capability to run in double conversion but are normally operated via a secondary power path.

 

This path provides unregulated power to the critical load and only interacts with the utility in the event it exceeds specified values. (They run on utility power until the UPS senses a problem and switches to an alternate source – typically battery or flywheel power.)

 

The structure of a line-interactive vs true online double conversion UPS leaves your site vulnerable to voltage transients and harmonic issues, and only provides a less than 0.3% efficiency gain over a double conversion Silicon Carbide-based UPS module.

 

The line-interactive UPS also tends to call upon the batteries more frequently than double conversion UPS modules, shortening the battery life and leading to costly battery change outs. If reliability is key, then double conversion is the best choice for critical loads.

Benefits of Double Online Conversion in
Critical Power Applications

 

In a true online double-conversion UPS, the inverter is always on, supplying a clean, reliable power supply essential to industries requiring uninterrupted uptime. 

 

Whether you operate a data center, hospital, communications network, manufacturing facility, or just rely heavily on access to the grid, a double conversion UPS will provide clean, uniform power to your equipment.

 

With the double conversion process smoothing out raw power fluctuations from brownouts, line noise, voltage transients and power outages, you’ll be less susceptible to downtime events that could cost millions. 

 

Ensure True 24/7 protection with Mitsubishi Electric SUMMIT Series® UPS

 

Online double conversion UPS systems are the preferred topology for mission critical applications because they lower the risk of electrical load loss. Their reliability and efficiency as well as increased Power Usage Effectiveness (PUE) increase their ROI.

 

The SUMMIT Series® from Mitsubishi Electric is the most efficient double-online conversion UPS on the market. When power fails, the SUMMIT Series® converts and conditions the supply so the flow that reaches your equipment is even and consistent.
