CDQ1S PClevel Dual Power Automatic Transfer Switch CDQ1s100/4P16A Key benefits Ensures continuous power by automatically detecting and switching between two power sources to minimize downtime. Reduces risk of electrical faults through mechanical and electrical interlocking, preventing simultaneous connection of both sources. Extends equipment lifespan with smooth contact switching and a stable design that supports repeated operations. Adapts to changing needs via modular functional expansion, allowing easy addition of monitoring or control modules. Main features Model and rating: CDQ1s100/4P16A, 4pole, 16 A Function: automatic transfer switch for dual power inputs, designed for PClevel applications and similar sensitive loads Safety and protection: mechanical and electrical interlocking plus multiple builtin protection functions to avoid short circuits and unsafe transfer conditions Durability: engineered for smooth contact engagement and a long operational life under normal use Modularity: supports a variety of functional modules for , monitoring, and enhanced control of transfer behavior Performance and compatibility Designed to integrate with dualsource power systems where automatic, reliable switching is required Suitable for installation in electrical panels, control cabinets, or dedicated transfer switch enclosures where a 4pole 16 A device is appropriate Compatible with common downstream equipment such as PCs, network devices, small servers, telecom gear, and essential household or office circuits that require uninterrupted power Typical applications Small server rooms and network closets: keeps critical IT equipment running by switching to backup power automatically when the main source fails Office and home backup circuits: protects workstations, routers, and other essential devices from unexpected power interruptions Telecom and control equipment: maintains continuity for communication hardware and control systems that cannot tolerate extended outages Why choose this model Specifically sized and rated for PClevel and similar sensitive loads, offering straightforward integration into existing electrical systems Combines automatic detection, reliable interlocking, and modular expansion to deliver a practical balance of safety, longevity, and adaptability Clear specifications and stable mechanical design simplify planning, installation, and maintenance without unnecessary complexity Installation and operation notes Confirm system voltage and upstream protections before installation to ensure compatibility with site electrical parameters Use appropriate mounting and wiring practices per local electrical codes and standards Consider available functional modules for monitoring, remote signaling, or custom transfer logic to match operational requirements
