SS-30P 13.8V 30A Regulated Bench Power Supply - Reliable DC Source

In this review the SS-30P 13.8V 30A bench power supply is assessed as a practical, compact AC-to-DC converter for radio operators and lab users who need a steady 13.8V DC source. The reviewer found the unit especially useful for CB, Ham, GMRS and LMR two-way radios, scanners and other 13.8V equipment because it delivers a reliable, low-noise output with built-in safety protections and multiple connector options. If you need a tabletop power source that replaces batteries and supports up to 30A total output, this unit is worth considering.

Key Features

• AC to DC conversion: Provides a constant 13.8V DC output from a 115V AC inlet so radios and bench gear run without batteries or external supplies.
• Dual connector options: Front-mounted Anderson connectors plus 5-way screw-type binding posts make connecting transceivers and test gear straightforward and flexible.
• High current capability: Capable of supplying up to 30A total output with individual connectors able to deliver high current for demanding devices.
• Safety protection: Built-in overheat, short-circuit, and overcurrent protection helps safeguard both the power supply and connected equipment.
• Active cooling: An internal cooling fan prevents overheating during sustained draw, supporting continuous operation for field radio use or bench testing.
• Simple plug-in operation: A switch-activated design and included AC power cord make setup quick and reliable for desktop placement.

Who It's For

The SS-30P is aimed at amateur radio operators, CB and GMRS users, and hobbyists who run 13.8V equipment and need a compact, dependable DC source on a workbench or in a fixed station. Its combination of binding posts and Anderson connectors suits users who switch between hardwired leads and quick-disconnect cables.

It is less suited for users who require extremely quiet fanless operation in noise-sensitive audio test environments, or for mobile use where a ruggedized, vibration-rated supply is required. If you need a very small low-power bench supply under 10A, a smaller unit may be more economical.

Pros & Cons

Pros

• Solid build quality and compact footprint make it easy to place on a desktop or tabletop.
• Low-noise voltage output reported by customers, suitable for radio transceivers up to about 100W.
• Versatile connection options with both Anderson connectors and 5-way binding posts.
• Comprehensive safety features including overcurrent and short-circuit protection.

Cons

• Built-in fan produces audible noise under load, which may be noticeable in very quiet rooms.
• Some customers report mixed experiences with the Anderson connector fit or preference compared to other quick-disconnect systems.

Frequently Asked Questions

Can this unit run a 100W transceiver?
Yes; customers report it powers 100W transceivers successfully when current demands stay within the 30A total limit and cooling is adequate.

Does it require any special wiring to use the Anderson connectors?
No special wiring is required; the front-mounted Anderson connectors accept standard Powerpole-style leads and the screw terminals accept hardwired connections.

Is the fan loud during normal operation?
The fan runs under load and is audible in quiet rooms; overall noise is acceptable for most bench and radio station uses but may bother sensitive audio test setups.
