SolaHD Automation Transformers

March 1, 2018
Emerson Industrial Solutions' transformers are electrostatically shielded for quality power.

SolaHD encapsulated transformers help industrial automation professionals lower the TCO through simplified installation, reduced maintenance requirements, and decreased cabling needs. Developed to provide the capacity required for larger loads in a single floor-mounted unit, the transformers comply with the latest NEC requirements for harsh and hazardous industrial locations, making them ideal for service in petrochemical facilities, wastewater treatment centers, and power generation plants.


SolaHD Floor Mount Automation Transformers feature a rugged enclosure encapsulated with electrical grade silica and epoxy that protects its electronics from dust, metal particles, and moisture while providing extra shock and vibration resistance. Engineered for maximum performance and versatility, the transformers meet Class I, Division 2/Class I, Zone 2 ratings, 3rd party certification (cULus), and feature an expanded kVA range up to 150 kVA to provide additional opportunities for engineers in industrial and hazardous locations. New certifications and configurations mean the transformer acts as a single solution for multiple NEMA applications.


One of the keys to the success of SolaHD Floor Mount Automation Transformers is an enclosure featuring removable, field-replaceable gland plates for ease of conduit entry, along with floor mounting brackets that reduce installation, maintenance, and cabling expense. A cover delivers superior hose and washdown capabilities to ensure sanitation procedures are safely performed in areas such as food and beverage production.


Optional stainless steel enclosures provide full NEMA 4X compliance where required. These upgrades represent important advances in transformer hardware as Emerson continues to drive progress across the entire power quality sector, with a focus on improving reliability, energy conservation, and value.
