Allen-Bradley SS3524 Automatic Battery Charger

The SS3524 Automatic Battery Charger provides a regulated float charge for 24 VDC lead‑acid battery banks, delivering a 27.2–27.6 VDC float output at up to 3 A to keep batteries ready while avoiding overcharging. Designed for industrial and commercial use, it is commonly installed in standby generators, emergency power systems, telecommunications equipment, and industrial control panels, and it serves as a direct replacement for the CH4624 charger. The unit accepts 100–240 VAC input at 45–65 Hz, maintains voltage regulation under 1%, and delivers >80% efficiency at full load, with protection features including reverse polarity, short circuit, current limiting, and overload protection. Its compact 0.72 kg form factor supports panel or chassis mounting, operates from 0°C to +40°C with 0–90% RH, and includes a built‑in charge‑fail relay output for monitoring, compatible with lead‑acid chemistries such as flooded, AGM, and gel.
