DITEK DTK-DR5B Low Voltage DIN Rail Surge Protector for 48V Circuit Pairs

Protect sensitive security and surveillance electronics with the DITEK DTK-DR5B low voltage DIN rail surge protector. Designed for low-voltage fire, access control and monitoring systems, this compact surge protection module defends two circuit pairs (up to 48 V) against damaging transients while preserving uptime. Its hybrid SAD and Gas Discharge Tube (GDT) design combines fast clamping with robust energy diversion, providing dependable protection for cameras, sensors, control panels and other critical devices. The removable, field-replaceable protection module simplifies service and replacement — reducing mean time to repair and lowering lifecycle costs for integrators and facility managers. DIN-rail mounting streamlines installation in telecom and equipment cabinets, and the unit is suitable for both AC and DC applications. TAA and NDAA compliance ensures the DTK-DR5B meets procurement requirements for government and enterprise projects. Ideal for security, surveillance, monitoring and fire applications where space, reliability and serviceability matter. Add the DITEK DTK-DR5B to your next installation to protect equipment and maintain system availability.
