CITEL DLAS Series – DIN Rail Surge Protection for Data and Telecom Lines
Type 2 SPD | 1-Pair Protection | GDT + TVS Technology | Visual Fault Indicator
The CITEL DLAS Series comprises high-performance Type 2 surge protection devices (SPDs) designed to safeguard data communication and signaling lines from transient overvoltages caused by lightning strikes and switching events. Engineered for DIN rail mounting, the DLAS Series is ideal for integration into control panels and enclosures where space is at a premium.
Utilising a hybrid protection approach that combines Gas Discharge Tube (GDT) and Transient Voltage Suppression (TVS) diode technologies, the DLAS Series offers both common-mode and differential-mode protection. This ensures the integrity of sensitive equipment connected to industrial buses, telecommunication lines, or signaling applications.
