Emerson Turns Up the Heat with the New SolaHD SDU AC-B Series DIN Rail UPS

The global automation market is projected to reach a staggering $300 billion within five years as conventional manufacturing facilities are transformed by installing digitized processes. With this growth brings the challenge of supplying reliable battery backup power to the tens of thousands of devices deployed in these processes. Traditional Uninterrupted Power Supplies (UPS) are simply too large or heat-sensitive to be installed in control cabinets or be integrated into machines, and virtually all lack network communications for remote diagnostics. 

By introducing its new SolaHD™ SDU AC-B UPS, Emerson is addressing the power challenge. The SDU AC-B UPS combines a very compact footprint with a wide operation temperature range (0° to 50° C), plus offers a network communications option supporting all major industrial protocols. Built rugged for harsh and hazardous locations, it helps manufacturers and data centers by bridging power failures during outages to allow for safe shutdowns of machinery, and by mitigating power quality issues that adversely affect critical loads, therefore minimizing work interruptions, long restart cycles and the loss of data at the point of use.  

As a current Emerson customer expressed: "We have a hard time selling when we can’t keep our datacenter up all the time. One outage is a multi-million-dollar loss along with damage to our brand. The SDU B-Series avoids these significant losses while reducing our total cost of ownership through advanced battery health checks and user replaceable batteries." 

Here is what makes the SDU AC-B the best UPS for your needs. 


Industrial engineers are facing increasing pressure to find additional space for components on DIN rails within control panels and enclosures, and in OEM machinery such as fabrication tools, robotics and CNC machines. Its compact footprint provides design flexibility without compromising protection to critical loads exposed to power aberrations. Measuring only 4.87 x 11.1 x 4.81 inches (HxWxD), it saves space while protecting against all types of power problems in critical applications that cannot afford downtime, including those requiring ODVA compliance.  


Heat is the enemy of UPS batteries, especially in non-climate controlled environments where elevated temperatures will dramatically shorten battery service life, such as steel mills, petrochemical plants or auto manufacturing. The SDU AC-B features a high heat, field replaceable battery rated from 32° to 122°F (0° to 50° C) that is thermally isolated from internal heat generating elements of the UPS. Combined with high-temperature grade components and an advanced battery management system, the SDU AC-B adds value and long-term reliability in high heat environments.  


As an option, the SDU AC-B has an integrated communication port that supports both active and passive modules. Installing an active module is suitable for both general purpose and for high-end applications with large I/O data transfer, fast network cycles and synchronization demands communicating on either EtherNet/IP, Modbus, Profinet or EtherCAT network protocols. Installing a passive module enables control of two relays. In addition, web monitoring is standard on the SolaHD SDU AC-B that remotely displays UPS status, alerts, SMS notification and a historical log.  


Engineers looking to deploy an industrial UPS in harsh and hazardous locations typically require a customized solution to match their infrastructure needs, which means more time spent on development and higher costs. Being able to withstand extreme environmental conditions, the SolaHD SDU AC-B eliminates the need for customized solutions, while ensuring service continuity and energy quality. It features a rugged metal housing along with a conformal coated PCB for corrosion resistance, plus has extensive ordinary, hazardous and offshore global certifications to operate safely in the presence of flammable gases and vapors.
