Product: CDQ0s dual power automatic transfer switch Model / Size: CDQ0s125/4125125A PC grade CDQ0s125/4125 125A Overview This CDQ0s dual power automatic transfer switch provides reliable automatic detection and transfer between two power sources to maintain continuous power to critical loads. The unit uses a PC grade housing for durable protection and is engineered for stable, longlasting operation. Key benefits Ensures power continuity through automatic detection and fast transfer between primary and secondary sources. Ideal where uninterrupted power is required. Reduces risk of incorrect switching with mechanical and electrical interlocking to prevent simultaneous closure of both sources. Delivers stable, smooth contact switching for extended service life and reduced maintenance. Modular design supports a range of functional modules for easy expansion and to match specific application requirements. Main features Automatic transfer operation that monitors input sources and switches without manual intervention. Mechanical and electrical interlocking protection to avoid short circuits between power sources. Multiple protection functions integrated for reliable operation under varying conditions. PC grade enclosure material for impact resistance and longterm durability. Rated current 125A as indicated by model designation. Functional modularity enabling additions such as control, signaling, and remote monitoring modules to improve conversion flexibility. Compatibility and performance Built to work as a dual power automatic transfer switch for systems requiring an automatic fallback source. Supports modular upgrades to adapt to different control schemes and monitoring requirements. Designed for smooth contact engagement and disengagement to limit wear and maintain consistent switching performance. Typical applications Commercial and industrial power distribution where uninterrupted supply is required, such as factory control panels and production lines. Backup generator and utility transfer for small to medium data centers and server rooms that need rapid and reliable source switching. Building services and critical electrical circuits in facilities management, including lighting distribution and essential equipment circuits. What to consider Verify system wiring and control module compatibility before installation. Use the model designation CDQ0s125/4125125A or CDQ0s125/4125 125A when specifying for procurement or integration to ensure correct rated current and configuration. Modular options allow tailoring the unit to monitoring and control needs without changing the core switch mechanism. This product is intended for electrical power transfer applications where automatic, reliable switching and long service life are required.
