Description
The HPS SG3A0030DK dry type transformer is a general-purpose distribution transformer engineered for reliable power distribution in industrial and commercial environments. Rated for 600 volts and below, it efficiently supplies power to appliances, lighting, heating systems, motorized machines, and other electrical loads. This model features a NEMA 3R enclosure, making it suitable for both indoor and outdoor use by providing protection against rain, snow, and environmental contaminants.
For non-linear load applications, it is recommended to consider the HPS Sentinel K series, which is specifically designed to handle harmonic distortion. The HPS SG3A0030DK 30 kVA transformer complies with North American efficiency standards, including U.S. DOE 10 CFR Part 431 (effective January 1, 2017) and Canada SOR/2016-311, Amd. 14 (effective December 9, 2016), ensuring high energy efficiency and regulatory compliance.
