Mechanicsburg, Pa.-based Automation Systems Interconnect Inc. (ASI) has introduced a new line of overvoltage and lightning protection modules.
Covering both the AC and DC sides of a solar PV network, the surge protectors use either metal oxide varistor or gas discharge tube technology to protect all components of the solar PV power system, the company says. The ASI AC surge protection modules for solar PV installations are available for single-phase 230 VAC and three-phase 230 V or 400 VAC circuits.
DC surge protection modules are available with ratings of either 600 Vdc or 1000 Vdc. Modules are DIN rail-mountable.
