SDU500B UPS by Emerson

Many battery backup solutions can be too large and heavy for use in control cabinet applications. They do not have the industrial communication protocols to support that environment; nor do they offer an operational temperature range required for use inside of a cabinet. These issues lead to decrease product reliability and reduced flexibility within your applications.

You need a reliable UPS that will maximize machine availability and minimize unplanned disruptions. A UPS with a compact footprint, so you can reduce overall panel size, or put more components into an existing control cabinet. A product that delivers stable power and higher efficiency, offers network communications for diagnostics, includes notable certifications, and withstands higher operating temperatures without compromising battery performance.

That’s why the SDU500B UPS by Emerson is the ideal choice for those who need reliable power, higher efficiencies, and extensive hazardous or offshore location certifications — helping customers improve their operations regardless of where it’s put to use.
