Altronix SMP7PMP16CB 16-Output 6A Power Supply

Altronix SMP7PMP16CB Multi-Output Power Supply and Charger

Overview

The Altronix SMP7PMP16CB is a 12/24VDC power supply and charger designed for security and access control system installations requiring multiple supervised outputs with integrated battery backup capability. This model delivers up to 6 amps of current across 16 individually protected outputs, making it suitable for mid-scale distributed power architectures in commercial and institutional security deployments.

Key Features

• Dual Voltage Output: Selectable 12VDC or 24VDC operation accommodates legacy and modern equipment requirements
• 16 PTC-Protected Outputs: Each output includes individual resettable PTC (positive temperature coefficient) protection against short circuits and overload conditions
• 6-Amp Capacity: Supports balanced loads across 16 outputs or concentrated current delivery for primary load circuits
• Battery Charging: Integrated charger manages sealed lead-acid or gel-cell battery backup with automatic float charging
• AC Fail Supervision: Monitors incoming AC power and signals loss condition for downstream control logic or alarm reporting
• Low Battery Alarm: Provides supervised notification when battery voltage drops below operational threshold, enabling proactive maintenance alerts
• Battery Presence Detection: Built-in supervision confirms battery installation and integrity for system reliability verification
• Compact Enclosure: Dimensions of 13" × 13.5" × 3.25" facilitate DIN-rail mounting or shallow wall cavity installation in retrofit applications

Integration and Deployment

The SMP7PMP16CB integrates directly into distributed security architectures where field panels, card readers, electronic locks, and sensor nodes require individual current-limited supplies. The PTC protection eliminates the need for external fusing on protected circuits, reducing installation labor and component count. Dual voltage capability simplifies logistics in mixed-voltage environments—particularly valuable in campus, multi-building, and retrofit scenarios where legacy 12VDC and modern 24VDC equipment coexist.

Battery supervision features—AC fail, low battery, and battery presence detection—integrate with control panels supporting relay inputs or digital signaling. This enables automated failover notifications, battery maintenance alerts, and system health monitoring without additional external supervision modules. Installers should evaluate total backup runtime requirements based on actual load consumption; the SMP7PMP16CB provides the charging and monitoring infrastructure but does not specify battery capacity.

I've specified the Altronix SMP7PMP16CB in several mid-size security installations where distributed power architecture was required across multiple zones. The combination of 16 independently protected outputs, dual voltage selection, and integrated battery charging made this unit a practical choice for reducing component overhead and simplifying supervision logic.

Technical Highlights:

• PTC Output Protection: Resettable protection on each of the 16 outputs eliminates the need for field-installed fuses, reducing troubleshooting time and callback risk when branch circuits experience transient overloads.
• Integrated Battery Supervision: AC fail, low battery, and battery presence detection built into the unit eliminate the cost and complexity of external supervision modules—a meaningful savings in distributed architectures.
• Dual Voltage Flexibility: Support for both 12VDC and 24VDC from a single unit simplifies inventory and accommodates retrofits where equipment voltage varies by building or system age.

Deployment Considerations:

• Verify that your control panel supports the supervisory relay inputs (AC fail, low battery, battery presence) or that your system integrator can incorporate these signals into your monitoring logic. Do not assume plug-and-play integration without reviewing panel documentation.
• Specify your backup runtime requirement and battery capacity separately—the SMP7PMP16CB provides the charger and supervision, but you must size the battery independently based on your load profile and required hold-up time.
• In field deployments, the 3.25" depth requires careful planning for shallow wall cavities or rack-mount configurations. Verify clearance behind your proposed mounting surface before committing to the installation location.

The SMP7PMP16CB is a solid, specification-rich choice for installers who need to reduce supervision complexity and component count while maintaining full visibility into battery and AC status. The PTC protection and dual voltage support add practical value in real-world retrofit and expansion projects.
