ABB's low-voltage products division has released a line of OVR PV UL 1449 3rd Edition, pluggable DC DIN Rail surge protection devices (SPDs) specifically designed for photovoltaic applications.
The new SPDs are designed to protect solar panels from damage from direct and indirect lightning strikes. Catastrophic damage from lightning strikes can ruin expensive solar equipment or cause long-term downtime, ABB warns. The PV-specific SPDs will be available in maximum discharge currents of 15 kA or 40 kA and with maximum continuous operating voltages of 600 VDC, 800 VDC and 1,000 VDC.
The new PV product range utilizes fast-acting metal oxide varistors to limit overvoltage to values compatible with the sensitive equipment connected to the network, ABB adds.
