Altronix Corp MAXIMAL77DV Access Power Supply 24VDC 20A

Product Description

The ALTRONIX CORP MAXIMAL77DV is an access control power supply designed to deliver 24 volts DC at 20 amps to distributed security and access control systems. It features 16 individually protected PTC (positive temperature coefficient) outputs, allowing technicians to power multiple access control devices from a single centralized unit. Input voltage is 220 volts AC. The MAXIMAL77DV is typically installed by low-voltage security technicians and integrators in commercial and institutional settings where multiple door controllers, electric locks, or readers require a reliable, fault-tolerant power source.

This power supply is suited for commercial access control installations requiring high-current, multi-output distribution. The 16 PTC-protected outputs provide automatic overcurrent protection on each circuit, reducing the need for individual fusing. It is appropriate for panel rooms, IT closets, and security equipment enclosures where centralized power distribution to multiple field devices is required. Security integrators and licensed low-voltage contractors are the primary installers.

Key Features

• 24 volts DC output at 20 amps total capacity
• 16 individually PTC-protected output circuits for automatic overcurrent protection
• 220 volt AC input voltage
• Centralized power distribution reduces field wiring complexity
• Designed for commercial access control and security system applications

Compatibility

Designed as an OEM-style replacement or direct installation unit for commercial access control power distribution applications requiring 24 volts DC multi-output power supplies.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical contractor in accordance with applicable NEC requirements for access control and security power supplies. Disconnect and lock out all input AC power before wiring or servicing the unit. Verify that total connected load does not exceed the rated output capacity before energizing. Secure the unit in a protected enclosure appropriate for the installation environment.
