The ALTRONIX CORP EFLOW3N4 is an access control power supply designed to deliver 12 or 24 volts DC at up to 2 amps of continuous output. It features 4 individually fused outputs, allowing technicians to distribute power to multiple access control devices while maintaining fault isolation across each circuit. This unit is a core infrastructure component in electronic access control installations, typically mounted in electrical rooms, server closets, or security equipment enclosures. Security integrators and licensed electricians install this type of supply as part of door controller, electric strike, and electromagnetic lock systems.
The EFLOW3N4 is suited for commercial and light industrial access control applications where a compact, multi-output DC power source is required. The selectable 12 or 24 volt output voltage makes it adaptable to a range of field devices including card readers, request-to-exit sensors, and electric locking hardware. The 4 fused outputs allow each branch circuit to be protected independently, reducing the scope of a fault event to a single zone rather than the entire system.
Designed as an OEM-style replacement or new-install power supply for commercial electronic access control systems requiring 12 or 24 VDC multi-output distribution.
Installation should be performed by a licensed electrician or qualified security systems integrator in accordance with applicable NEC requirements. Disconnect and lock out all AC input power before servicing or wiring output connections. Verify the output voltage selector is set to the correct voltage for the connected field devices before energizing. Do not exceed the rated 2 amp aggregate output current across all fused branches.
