RDL PS-24AS 500mA AC/DC Power Supply - Compact Reliable Power

In this review of the RDL PS-24AS power supply, the bottom line is simple: this is a compact, reliable AC/DC adapter aimed at small installations that need a steady 24V feed at modest current. It is best for technicians and hobbyists who install stick-on modules or small rack-mounted accessories and want a no-frills, purpose-built power source. The review focuses on real-world use: straightforward hookup, predictable 500mA output behavior, and the convenience of a device intended for continuous operation rather than intermittent bench use.

Key Features

• 24V output: Provides a consistent 24V DC supply suitable for low-power stick-on modules and small peripheral devices.
• 500mA current: Delivers up to 500mA which is enough for lightweight electronics without forcing larger, more expensive supplies.
• AC/DC design: Accepts standard AC input and produces regulated DC output so it plugs into typical mains without extra converters.
• Compact form factor: Small size makes it easy to mount near the powered devices or inside racks where space is limited.
• Purpose-built simplicity: No extra bells or complex controls, reducing points of failure for continuous operation.

Who It's For

This unit is aimed at audio/video installers, systems integrators, and electronics hobbyists who need a dependable 24V source for light loads like stick-on modules or small rack accessories. The steady 500mA rating is well suited for devices that draw modest current consistently rather than peak-hungry gear.

Those who should look elsewhere include users powering multiple high-draw devices or any equipment requiring more than 500mA or advanced features such as adjustable voltage, battery backup, or surge filtering. For higher capacity or multifunction power systems, a larger power supply or UPS is a better fit.

Pros & Cons

Pros

• Reliable regulated 24V output that keeps small electronics stable during continuous operation.
• Sized for easy installation near stick-on modules or inside equipment racks with limited space.
• Simple AC/DC design reduces complexity and potential failure points for long-term use.

Cons

• Limited to 500mA, so it is not suitable for higher-current devices or multi-device setups without additional supplies.

Our Verdict

The RDL PS-24AS is a straightforward, well-targeted power supply for small installations that need a reliable 24V DC source. Its simplicity and compact size make it good value for technicians and hobbyists who require continuous, predictable power for light-load devices, but it is not intended for higher-current or feature-rich power systems.

Frequently Asked Questions

Can this power supply run continuously?
Yes. The AC/DC design and regulated output make it suitable for continuous operation powering small devices.

Is 500mA enough for multiple devices?
500mA is intended for single light-load devices; powering multiple items will likely exceed its capacity and is not recommended.

Does it provide battery backup or surge protection?
No. This unit is a basic regulated supply and does not include battery backup or advanced surge protection features.
