Altronix Corp MAXIMAL33RD Access Power Supply 12VDC 24VDC

Product Description

The ALTRONIX CORP MAXIMAL33RD is a multi-output access control power supply designed to distribute and protect low-voltage DC power across large access control and security installations. It delivers 12VDC or 24VDC at up to 12 amps total output capacity and provides 16 individually protected PTC (polymeric positive temperature coefficient) outputs. Each PTC output self-resets after an overcurrent condition, eliminating the need to manually replace fuses. Licensed security and low-voltage electricians install this unit in commercial and institutional applications where multiple door controllers, readers, or electrified hardware require clean, regulated power.

The MAXIMAL33RD is suited for commercial access control systems where a central power distribution point must feed a high number of field devices simultaneously. Typical installations include multi-door access control panels, gate operators, and card reader networks in commercial buildings, data centers, schools, and government facilities. The selectable 12VDC and 24VDC output voltage makes it adaptable to a variety of field device requirements without requiring separate supplies.

Key Features

• Selectable 12VDC or 24VDC output voltage for flexible system design
• 12 amp total output capacity supports large multi-device installations
• 16 individually fused PTC outputs provide per-circuit overcurrent protection
• Self-resetting PTC fuses eliminate manual fuse replacement after fault conditions
• Designed for commercial access control power distribution applications

Compatibility

Designed as an OEM-style replacement or direct-install access power supply for commercial low-voltage access control systems requiring multi-output 12VDC or 24VDC distribution.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with applicable NEC requirements for Class 2 power-limited circuits. De-energize all connected circuits and disconnect AC mains before wiring inputs or outputs. Verify total connected load does not exceed the 12 amp rated output capacity before commissioning. Follow the manufacturer data sheet for input wiring, output terminal assignments, and enclosure mounting requirements.
