Altronix AL168175CB 8-Output 16VAC Control Panel PSU

Altronix AL168175CB 16VAC Power Supply

Overview

The Altronix AL168175CB is a regulated 16VAC power supply designed for security and access control system installations requiring distributed power delivery across multiple protection circuits. Configured with 8 individually protected outputs and housed in a BC100M enclosure, this unit delivers 10 amps at 16VAC from a standard 115VAC input source, making it suitable for hardwired camera systems, door locks, intercoms, and auxiliary security devices in small-to-medium installations.

Security integrators and system designers select the AL168175CB when circuit isolation and individual output supervision are priorities. The 8-output configuration allows independent branch circuit management, reducing the risk of cascading failures when a single load experiences a fault condition.

Key Features

• Input Power: 115VAC, single-phase
• Output Voltage: 16VAC regulated
• Maximum Output Current: 10 amps total capacity
• Number of Outputs: 8 individually protected circuits
• Protection Type: PTC (Positive Temperature Coefficient) thermistor outputs for automatic overload and short-circuit protection
• Enclosure: BC100M form factor for wall or DIN-rail mounting
• Load Distribution: Shared 10A capacity across 8 outputs allows flexible allocation based on connected device requirements
• Automatic Reset: PTC outputs reset automatically when fault conditions clear, eliminating manual intervention

Integration & Compatibility

The AL168175CB operates as a standalone power distribution unit within larger security system architectures. Its 16VAC output is compatible with legacy and modern access control panels, intercom systems, and auxiliary device power requirements common in analog and hybrid security installations. The modular 8-output design integrates into custom power distribution schemes where per-circuit supervision and independent load control are required.

The BC100M enclosure dimensions support standard wall mounting or integration into electrical distribution cabinets. The unit's regulated output voltage ensures consistent performance across connected devices, accommodating voltage drop conditions typical in extended wire runs to remote locks, speakers, and sensor devices.

Technical Operation

Each of the 8 outputs on the AL168175CB incorporates PTC thermistor protection, a passive component that automatically increases electrical resistance when current exceeds safe thresholds. This self-resetting mechanism eliminates the need for replaceable fuses or manual breaker reset, reducing ongoing maintenance overhead. When a short circuit or excessive load occurs on any single output, only that circuit shuts down; the remaining 7 outputs continue operating normally, maintaining power to critical devices.

The 16VAC specification at 10A total capacity requires integrators to calculate per-output load distribution during design. A system drawing 10A across all 8 outputs averages 1.25A per circuit; however, individual outputs can handle higher current if total system draw remains below 10A. This flexibility accommodates both balanced load scenarios and applications where one or two outputs serve higher-current devices while others support lighter loads.

The AL168175CB is specified for standard indoor operating environments common in commercial security installations. Its regulated output maintains voltage stability regardless of input AC line fluctuations within normal utility ranges, protecting connected devices from voltage-induced faults.

During system planning for multi-zone access control and camera power distribution, the Altronix AL168175CB offers practical advantages in fault isolation and load management. Its 8-output configuration with individual PTC protection aligns well with installations where circuit independence reduces troubleshooting complexity and minimizes downtime from single-point failures.

Technical Highlights:

• PTC Output Protection: Each of the 8 outputs auto-resets without manual intervention, reducing service callbacks and field maintenance overhead in multi-branch installations.
• Regulated 16VAC Output: The AL168175CB maintains consistent voltage delivery across the 10A capacity, ensuring compatible operation with legacy door strike controllers, magnetic locks, and intercom systems without external regulation.

Deployment Considerations:

• Verify total system current draw does not exceed 10A across all 8 outputs during load testing. Oversizing by 20–30% is prudent for margin against future expansion.
• Position the BC100M enclosure in a climate-controlled environment (standard indoor conditions) and ensure adequate ventilation around the unit to support passive cooling during sustained operation.
• Segregate high-current outputs (door locks, magnetic devices) from sensitive low-current circuits (intercom audio, sensor lines) when possible to minimize interference and ground bounce.

The AL168175CB is a reliable workhorse for mid-sized security systems where distributed power protection and independent load control eliminate the need for costlier, more complex supervised power management. Its self-resetting PTC outputs and straightforward AC input make it a fit for integrators standardizing on dependable, low-maintenance power infrastructure.
