RQG 13.8V 30A Bench Power Supply for Ham Radio – Regulated DC Switching PSU with Noise Offset Control and Cigarette Plug

Overview and Capabilities

The RQG 13.8V 30A bench power supply is designed to power radio setups with a stable, regulated DC output. It converts AC 110V input to a clean 13.8V supply capable of peak currents up to 30A, with a continuous rating around 20A. This makes it suitable for CB, VHF, and UHF HAM radio configurations, keeping your equipment running reliably during long sessions or field days.

Key to its appeal is a thoughtful blend of performance and practical features. The unit employs a switching topology that offers efficient heat management, with a front-facing cigarette plug socket ideal for handheld radios or portable devices up to 10A. A backlit meter provides clear voltage or current readings at a glance, even in dim environments, and can be toggled with a single button for quick checks during operation.

Key Features and Controls

• 30A peak output with 20A continuous current, ideal for demanding radio setups
• Analog DC output with a backlit display and a user-friendly switch for instant monitoring
• Adjustable noise offset control to tailor power delivery to frequency and mode variations
• Front 10A cigarette-plug socket to power handheld radios and portable devices
• Built-in protection: short-circuit protection, automatic current limit up to 30A, plus fuse protection
• Cooling fan for steady operation and enhanced heat dissipation

Real-World Use Scenarios

• Base station bench setups where a stable, clean DC supply helps maintain equipment performance
• Field days and temporary installations requiring reliable power for radios and accessories
• Powering transceivers and auxiliary gear on desks or portable workstations
• Quickly integrating handheld radios and portable devices via the front cigarette plug

How to Get the Most from It

Connect the unit to a standard 110V outlet, set your required 13.8V output, and monitor the backlit meter as you power up. Use the noise offset control to minimize pulse noise that can arise from switching power delivery, especially when operating at certain frequencies or modes. The compact dimensions and robust build make it a practical addition to a home lab or mobile setup, offering a measured balance of power, safety, and convenience.

Note: Performance can vary with connected load and equipment. This power supply is designed to provide flexibility and reliable operation, not guarantees of specific results. With thoughtful configuration, you may experience steadier operation across your radio and testing tasks.
