ALTRONIX AL175ULX 12/24VDC Power Supply/Charger - Reliable Output

In this review of the ALTRONIX AL175ULX, the bottom line is simple: this is a compact, purpose-built power supply/charger ideal for small to medium security, access control, and communications installations that require either 12VDC or 24VDC outputs with protected current. Installers and technicians will appreciate the steady, Class 2 rated power and built-in PTC protection that reduce the need for extra external protection. The unit converts standard 115VAC 60Hz input into two selectable, PTC protected outputs, making it a straightforward choice when dependable, limited-current DC power is needed.

Key Features

• Dual Voltage Output: Offers selectable 12VDC or 24VDC operation to match a range of devices without swapping units.
• Class 2 Rated Supply: Provides a power limited output that simplifies code compliance for low-voltage applications.
• 115VAC Input: Runs from standard 115VAC 60Hz mains, so it fits typical building power without special wiring.
• PTC Protected Outputs: Built-in PTC protection helps guard connected devices and wiring against overloads and short circuits.
• 1.75 Amp Capacity: Delivers up to 1.75A across the output configuration, suitable for modest accessory loads and small control panels.
• Simple Integration: Its focused feature set keeps installation and troubleshooting direct for professional installers.

Who It's For

The AL175ULX is aimed at installers, security integrators, and IT technicians who need a compact, reliable DC supply for powering cameras, access control panels, or small communications gear in commercial or residential sites. It is particularly useful where a Class 2 limited power source and basic output protection are preferred to reduce additional circuit protection needs.

This is less suited for projects demanding high current or battery-backed UPS features; systems that require sustained high loads or integrated battery charging at higher amperage should consider larger power supplies or dedicated battery chargers instead.

Pros & Cons

Pros

• Selectable 12VDC or 24VDC operation covers common voltage requirements without extra hardware.
• PTC protected outputs reduce the risk of wiring faults impacting connected devices during faults.
• Class 2 rated, power-limited outputs simplify compliance for low-voltage installations.
• Compact footprint and straightforward wiring make field installation faster.

Cons

• Maximum 1.75A output limits use to low-to-moderate power devices and small accessory loads.
