DC Surge Protector LSD-series is TVSS (Transient Voltage Surge Suppressor) or Surge Diverter that provides high energy surge diversion for protection against power surge caused by external sources as lightning strikes or switching circuit at DC power supply section. LSD-series Surge Diverter absorbs and diverts excess voltage and current to the low impedance path and to ground. LSD-series DC surge protector is designed for mounting at point-of-entry / service entrance, DC main switchboard or distribution board and load center location for providing DC surge protection for battery system, stand-alone solar power system, PV-grid tie system, solar water pump system, DC power supply system, data control & acquisition equipment, telecommunication sites, etc.
