ALTRONIX AL600ULPD4 115 VAC Power Supply Charger - Reliable Regulated

In this review the ALTRONIX AL600ULPD4 is evaluated as a compact, purpose-built power supply charger aimed at installers and facilities that need dependable low-voltage power for security and access control equipment. The single biggest reason to consider it is its combination of an automatic switch and a built-in charger that delivers filtered, electronically regulated 12/24 VDC output from a 115 VAC input, simplifying installations that require both standby battery charging and stable power delivery.

Key Features

• 115 VAC input: Provides a standard mains connection so the unit can be installed in most commercial and residential electrical environments without special wiring.
• 12/24 VDC selectable output: Allows flexible compatibility with a variety of security devices and access control components that require either 12 V or 24 V DC.
• Built-in charger: Integrates battery charging to maintain standby power for connected systems, eliminating the need for a separate charger module.
• Filtered and electronically regulated output: Delivers clean, stable DC power to help protect sensitive electronics and reduce nuisance resets or false triggers.
• Automatic switch function: Ensures seamless transfer between mains and battery power, keeping connected equipment running during power interruptions.

Who It's For

The AL600ULPD4 is well suited for professional integrators, security technicians, and facilities managers who install or maintain access control systems, alarm panels, and other low-voltage devices that need continuous, regulated power with battery backup. Its selectable 12/24 VDC output and integrated charger make it especially useful where space and simplicity matter.

Less appropriate for hobbyists or general consumers who do not require a UL-listed, commercial-style power supply charger or who prefer plug-in wall adapters. Also, projects that demand very high output current beyond the listed 3.5 A / 6 A capability should consider higher-capacity supply options.

Pros & Cons

Pros

• Integrated charger and automatic switch provide a neat, single-unit solution for systems that need battery backup.
• Electronically regulated and filtered output helps protect downstream electronics from voltage swings and electrical noise.
• Selectable 12 V or 24 V output increases versatility across different devices and installations.

Cons

• Output current is limited to the specified 3.5 A / 6 A range, so it may not meet demands of larger or multiple high-draw devices.
