Surge Arresters Protect Photovoltaic Systems

The VAL-MS 1000DC/2+V-FM protects two-position, dc-voltage photovoltaic systems up to 1 kV and is also available for other common voltages in small-scale photovoltaic systems and power systems (12 to 600 Vdc). The rail-mountable components protect both insulated and solidly grounded systems. Protective circuits are both thermally and dynamically monitored. Additionally, the VAL-MS surge arresters are available with or without remote indication contact. PHOENIX CONTACT INC., Harrisburg, PA. (800) 322-3225.
