Altronix Corp MAXIMAL11D Access Power Supply 16 Ptc

Product Description

The ALTRONIX CORP MAXIMAL11D is a dual-voltage access power supply designed for professional access control and security system installations. It delivers 12 volts DC at 8 amps or 24 volts DC at 6 amps and provides 16 individually protected PTC (positive temperature coefficient) outputs. Each PTC-protected output automatically limits current during a fault condition, protecting downstream devices and simplifying troubleshooting. This unit is intended for installation by licensed security and low-voltage electricians in commercial and light industrial environments where multiple access control devices require distributed, protected power.

The MAXIMAL11D is suited for commercial access control panels, door hardware, electric strikes, magnetic locks, readers, and other low-voltage security devices that require stable regulated DC power. Its 16 PTC outputs allow a single supply to serve multiple independently protected circuits across a distributed system. Installations commonly include multi-door access control deployments in commercial buildings, schools, and facilities requiring centralized power distribution with per-circuit fault protection.

Key Features

• Dual voltage output: 12 volts DC at 8 amps or 24 volts DC at 6 amps
• 16 individually PTC-protected output circuits for automatic fault isolation
• PTC resettable overcurrent protection eliminates the need to replace fuses after a fault
• Designed for access control, security, and low-voltage system power distribution
• Single enclosure consolidates power distribution for multi-device installations

Compatibility

Designed as an OEM-style power supply for commercial access control and low-voltage security systems requiring distributed 12 volts DC or 24 volts DC regulated power across multiple protected outputs.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical contractor in accordance with applicable NEC requirements for power-limited circuits. Disconnect and de-energize all circuits before wiring outputs to downstream devices. Verify that the total load across all active PTC outputs does not exceed the rated amperage for the selected output voltage. Do not mix 12-volt and 24-volt device loads on the same supply output without confirming system voltage compatibility.
