Industrial CH2805 Intelligent Dual Battery Charger

The CH2805 Intelligent Dual Battery Charger is an intelligent automatic generator battery charger designed for standby generator systems, delivering regulated charging for both 12V and 24V DC battery systems with automatic voltage detection and seamless auto-transfer between voltages to keep starting batteries ready for reliable generator start‑up during power outages. It offers a 5A output and uses constant current, constant voltage, and float charging (CC/CV/float) with an input range of 160–250 VAC and 20–100 Hz, supporting 12V and 24V lead-acid, AGM, or GEL batteries used for engine starting and control circuits. Protective features include over‑voltage, over‑current, short‑circuit, and reverse polarity protection, and the unit achieves >80% typical full‑load efficiency; mounting is panel or enclosure mount for easy integration in generator sets, ATS control panels, telecom backup systems, and industrial control cabinets. Common replacements include CH2806 (6A) and CH2810 (10A), as well as SmartGen BAC06A/BAC05A series.
