Fixed 13.8V output for radio gear
This desktop bench supply delivers a fixed 13.8 V DC output from a 110 V AC input, providing up to 30 A peak and 20 A continuous current. It is built for communication equipment such as CB radios, scanners, and HF, VHF or UHF ham radios. The unit includes a front-panel 12 V cigarette-lighter socket rated to 10 A for portable devices. A back-lit volt/ampere meter allows one-key switching between voltage and current readouts.
Input tolerance and ripple limits
The supply accepts 110 V AC ±10 % at 60 Hz and maintains output voltage regulation within 2 %. Ripple voltage stays below 80 mVp-p at rated load. Protection features include short-circuit and over-current safeguards plus a user-replaceable 8 A fuse. A built-in cooling fan prevents overheating during extended operation.
20 A continuous headroom for typical stations
Continuous rating of 20 A handles most single-transceiver setups with margin for accessories. The 30 A peak covers short transmit bursts but sustained high-power amplifiers will exceed the continuous limit. The 10 A cigarette-lighter socket suits low-draw peripherals only. The metal-cased unit weighs about 1.5 kg and measures 150 × 70 × 220 mm for bench placement.

Otázky k tomuto produktu
Should I pick the 20 A continuous or the 30 A peak rating for my radio?
The unit delivers 20 A continuously and can supply up to 30 A for short bursts; choose the 20 A figure for sustained loads and the 30 A figure only for brief peaks.
What does the 13.8 V fixed output mean when the supply is powering my ham radio?
It provides a steady 13.8 V DC with less than 2 % voltage variation and under 80 mV ripple at full load, giving stable power for HF, VHF and UHF transceivers.
The front panel has a 12 V cigarette lighter socket — what current can it actually handle?
The socket is rated for 10 A, so any device plugged into it must draw 10 A or less while the main terminals supply the remaining capacity.
