Support critical low-voltage systems with a power supply/charger built for security infrastructure. The Altronix EFLOW4NX delivers 12 or 24 VDC output at 4 A, giving integrators a flexible power source for equipment that must stay online and recover cleanly after interruptions. By combining supply and charging functions, it reduces the number of separate components required in the cabinet and simplifies system design. This model is suited to installations where compliance matters as much as uptime. UL/CUL listing, CE marking, and CSFM approval make it easier to specify in environments with formal electrical and life-safety requirements. For procurement teams, that means fewer exceptions during review and a cleaner path through project approval. Choose this unit when you need a compact power stage for access control panels, alarm hardware, or other DC devices that depend on consistent voltage. The 4 A output provides enough headroom for many small-to-mid-size deployments without moving to a larger, more expensive supply. It is a straightforward way to protect downstream electronics while keeping battery-backed operation organized and serviceable.
