Space-saving type suitable for built-in devices! SPD that protects the AC power circuit from lightning surges.
The "PMZ type" is a power supply SPD (surge protective device) suitable for incorporation into devices such as PCS (power conditioners) used in solar power generation and within lighting panels. In the event of degradation failure, it prevents abnormal heating through its built-in disconnection mechanism. It is equipped with a highly visible LED for degradation failure indication. 【Features】 ■ Space-saving design suitable for incorporation into devices ■ Can simultaneously protect between lines and between ground ■ Complies with JIS C 5381-1 Class II ■ Compliant with the Ministry of Land, Infrastructure, Transport and Tourism's Building Equipment Design Standards and the Ministry's Standard Specifications for Public Building Construction ■ Compliant with RoHS Directive For more details, please refer to the catalog or feel free to contact us.

Company information
Since its establishment in 1930, Sanko Shiya has expanded its business in response to the needs of the times, ranging from the design and manufacturing of communication safety devices and lightning rods to the design and manufacturing of meteorological observation instruments and optical technology-related equipment. Additionally, we established Franklin Japan (in Sagamihara City), a lightning and meteorological information company, and provide high-precision lightning strike information services through a lightning observation network installed across Japan, solidifying our position as the world's only comprehensive company related to 'lightning,' from observation to protection.
