Specialty Concepts ASC
ChatGPT said:
Specialty Concepts’ ASC Series Automatic Sequencing Chargers are rugged, solid-state photovoltaic charge controllers built for small to mid-sized off-grid systems, renowned for their sub-0.1% failure rate and fully encapsulated, waterproof design. Available in 12 V and 24 V models (with 6 V, 36 V, and 48 V options by special order) and rated from 1 A to 16 A, these controllers support 1–4 panel arrays and larger parallel systems. Each unit uses a simple shunt-type regulation scheme with blocking diodes to prevent reverse leakage, while optional temperature compensation and low-voltage disconnect features provide added battery protection and longevity. UL-recognized, CSA and FM approved, RoHS compliant, and made in the USA, the ASC Series delivers proven, maintenance-free reliability for remote instrumentation, industrial control, and other critical off-grid applications.
