Since1937 CITEL, Inc. has been specializing in the manufacturing of reliable Surge Protection Devices (SPD). CITEL has since expanded its surge protector lines to protect Grid-Tie Solar Power Systems. CITEL's DS50PV is surge rated at 40kA 8/20us, and engineered to protect against indirect lightning, AC utility grid surges, and internally generated switching transients. CITEL model DS60PV is a Heavy Duty DC surge protector, rated to withstand a direct lightning strike (10/350us waveform) as defined by ANSI/IEEE C62.41-2002 and IEC 61643-11. It is typically installed at the DC input to the inverter of a solar power system. These din rail mount devices can be integrated into a PV combiner box or standalone enclosure. CITEL is also pleased to announce model DS50PV as the first UL recognized DC Surge Protector with replaceable modules.
