The ALTRONIX CORP MAXFIT16A4 is a multi-output access control power supply designed to deliver reliable low-voltage power in access control and security system installations. It supports both 12-volt and 24-volt output at up to 4 amps, making it suitable for powering locks, readers, controllers, and related peripherals. The MAXFIT16A4 is built for professional installation in commercial and light-industrial environments where stable, regulated power distribution is critical to system performance. Licensed security and low-voltage electricians are the primary installers of this class of equipment.
The MAXFIT16A4 is used in access control system panels where multiple low-voltage devices require dedicated, distributed power. It is a fit for new installations and retrofit projects where centralized power management is needed. The ACM4 access control module and BC750 battery charging circuit references in the product data suggest this unit integrates power distribution with battery backup support, making it appropriate for installations requiring continuous operation during utility outages.
Designed as an OEM-style replacement or direct-install power supply for professional access control systems requiring 12-volt or 24-volt regulated power distribution.
Installation should be performed by a licensed low-voltage electrician or security systems technician in accordance with applicable NEC requirements for low-voltage power supplies. Disconnect and de-energize all circuits before servicing or connecting the unit. Verify output voltage selection matches the requirements of all connected devices before applying power. Follow the manufacturer wiring diagram and local AHJ requirements for enclosure and grounding.
