LS ELECTRIC said on the 5th that it obtained UL certification for its latest power conversion system (PCS), a core component of energy storage systems (ESS). UL (Underwriters Laboratories) is a U.S. nonprofit testing organization, and electrical products sold in the United States must receive UL certification.
A PCS is a device that performs an inverter function, converting electrical energy stored in batteries in direct current (DC) to alternating current (AC), and is one of the key components that make up an ESS along with batteries. The certified product is the second-generation PCS of the "MSSP (Modular Scalable String Platform)" developed by LS ELECTRIC to target the global market. The product enables stable cooling in high-output environments.
In this certification process, LS ELECTRIC passed a total of 52 test items, including overload and short-circuit safety tests, uninterruptible operation tests, and islanding operation tests, to meet varying regional regulations and certification requirements in places such as California, Hawaii, and Canada. LS ELECTRIC began securing UL certifications in 2014 and has obtained about 300 to date.
An LS ELECTRIC official said, "UL certification is a prerequisite for entering the North American market and a foundation for providing safe and efficient energy solutions to global customers," adding, "based on local certifications, we plan to expand customized solutions targeting a wide range of customers, from ESS for large power plants to commercial and industrial ESS."
