Emerson Expands Power Supply Portfolio to Add Design Flexibility in Hazardous Conditions

April 13, 2021

Recently, Emerson announced that it has expanded its SolaHD SVL DIN rail power supplies to include economical, three-phase versions engineered for use in both ordinary and hazardous locations within petrochemical refineries, chemical plants, wastewater treatment centers, and auto manufacturing facilities, among others. Power factor correction, along with overcurrent, overvoltage and short circuit protection, adds to their reliability and helps provide industry-leading efficiencies from 86% to 92%.

Ideal for high volume, controlled environments with essential power quality requirements, the new SVL models deliver 24Vdc output in Class I, Division 2 (C1D2) hazardous locations with 5-, 10-, or 20-amp output, equivalent to 120, 240, or 480 watts, respectively. A 40-amp 960 watt version is also available for ordinary locations, assuring maximum design flexibility. C1D2 models provide a safe way to tap three-phase power in hazardous locations where lighting systems, motors, pumps and other heavy-duty equipment are commonly found. 

“Reliability is critical in a power supply. SolaHD SVL three-phase power supplies are a cost optimized solution for equipment that needs protection from shock, vibration or temperature to prevent production downtime,” said Mark Dziedzic, Senior Product Marketing Manager for Emerson’s SolaHD Power Quality Solutions business. “Convection cooling reduces the temperature of internal components without the need of a fan that may serve as a failure point. Also, a diagnostic LED located on the power supply visually indicates operational status from a distance for added safety and convenience.”

SolaHD SVL power supplies are an excellent alternative to embedded open frame switchers. The clip-on DIN rail mounting capability provides quick, hassle-free installation. The universal three-phase input voltage enable the power supplies adapt to locally available power, and screw terminal connections make them exceptionally simple to wire.

In addition to the three-phase models, SolaHD SVL power supplies are available in single-phase versions ranging from 15 to 480 watts in 5-, 12-, 24- and 48-volt combinations. All SLV power supply models meet UL 508 requirements for industrial control equipment and UL 60950 requirements for information technology equipment and CE low voltage directive standards for applications in all world areas.
