Professional DC Power Supply

The TekPower TP50SW delivers a stable 13.8 V DC output with an adjustable range of 9 to 15 V and a maximum current of 50 A. It is designed for ham and CB radio operators who need reliable power for transceivers and amplifiers. A rear terminal block and a front-mounted cigarette socket provide two convenient connection options.

Sustained Load Behaviour

The unit uses an analog switching topology that maintains excellent line and load regulation with low ripple and noise during continuous operation. Built-in overload and short-circuit protection automatically safeguard the supply and connected equipment when current demands peak. A fused input adds an extra layer of safety for extended duty cycles.

Setup Checks

Verify that your AC mains provide 110 V at 60 Hz before connecting the supply. Ensure the total draw of all attached radios and accessories stays within the 50 A maximum rating. Confirm that your cabling and connectors are rated for the expected current to avoid voltage drop or overheating.

Questions about this item

How much heat and fan noise does the 50 A output produce when the supply runs continuously?

The unit is an analog switching design rated for 50 A max current at 13.8 V with low ripple and noise, so it runs cooler and quieter than linear supplies under sustained load.

What AC mains connection and fuse rating do I need on my bench for the 110 V 60 Hz input?

It requires a standard 110 V AC 60 Hz outlet; the built-in overload and short-circuit protection handle fault currents, so no external fuse beyond the branch-circuit breaker is required.

Will the 9–15 V adjustable range and cigar socket safely power my existing 13.8 V ham radio and CB equipment?

Yes, the fixed 13.8 V rear output and the front cigar socket both deliver 13.8 V nominal, adjustable from 9 V to 15 V, matching the voltage your legacy gear expects.
