Pluggable surge protection for photovoltaic systems from Phoenix Contact
Phoenix Contact’s Valvetrab MS surge arresters protect photovoltaic systems up to 1000 V. The VAL-MS 1000DC/2+V-FM protects two-position dc voltage systems up to 1,000 volts. Other voltages are available.
Phoenix Contact’s Valvetrab MS surge arresters protect photovoltaic systems up to 1000 V. The VAL-MS 1000DC/2+V-FM protects two-position dc voltage systems up to 1,000 volts. Valvetrab MS is also available for other voltages commonly used in small-scale photovoltaic systems and power systems (12 V to 600 V dc).
The rail-mountable arresters protect both insulated and solidly grounded systems. The protective circuit is thermally and dynamically monitored. In the event of damage, it disconnects the arrester from the generator, the company says. The VAL-MS surge arresters are available with or without remote indication contact.
Phoenix Contact develops industrial electrical and electronic technology, including components and system solutions for industrial and device connection, automation, electronic interface and surge protection.
