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, as well as within lighting panels. In the event of degradation failure, it prevents abnormal heating through an internal 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 to ground with a single unit - Complies with JIS C 5381-1 Class II - Conforms to the Ministry of Land, Infrastructure, Transport and Tourism's Building Equipment Design Standards and the Ministry of Land, Infrastructure, Transport and Tourism'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 founding in 1930, Sankosha has expanded its business in response to the needs of the times, from the design and manufacturing of communication security 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 weather information company, and provide high-precision lightning strike information services through a lightning observation network installed throughout Japan, solidifying our position as the world's only comprehensive company related to 'lightning,' from observation to protection.
