Review: PROVIDES A LINEAR AMPLIFIER WITH A FULL FIFTY AMPS AT 12.5 VOLTS FOR A COOL 300 WATSS OUTPUT - THIS IS A NICE FIFTY AMP SUPPLY. TO LIKE} Attractive well made heavy weight Good design features Dual Meters for Voltage.... (adjustable) Lower current 12V. Cigar plug receptacle on front panel for Hand Held, or Other. Good heavy power cord. Solid attachment to supply good solid mating. I have been using this power supply everyday for twenty four hours a day at standby condition, and power up for at least one half hour for a weekday netcall. It has performed flawlessly. Stable, extremely accurate voltage control once set. It is a solid piece of gear for my VHF equipment in my Ham Radio Station. I know my equipment since I have been a radio amateur a bit longer than most, I once held an FCC First Class Radio Telephone license and was an FAA Certified engineer keeping all airborne heavies safe and happy. This is a very nice power supply. Gives up little warmth for a full demand load. For a HAM radio operator, or anyone wishing a good DC bench supply this Fifty Amp is great equipment for the price. You could not make one as nice for the price. I am certain of that. I am awarding the Supply a A GIANT FIVE STAR RATING. for performance and overall value.
Review: Nice power supply - I like this little supply, and it is little, small and light. This is my first switching supply. I always liked the ones with the big, heavy power transformers. I am using it to power a vhf ham transceiver, which draws 20 amps on high power. The supply provides this effortlessly, does not get hot and the cooling fan has not kicked on at all. There is no radio noise from the unit. I can vary the voltage from 9 to 15 volts, but I just leave it on 13.8 and it stays there, with no lag under a 20 amp load. I like having separate voltage and current readings, and they are large, bright and easy to read. I really have no complaints, but it would have been nice to have a second pair of power jacks on the back panel. The single pair of back panel connectors do not appear to be particularly heavy duty for a 30 amp connection.

## Questions & Answers

**Q: What is the spade lug size needed for this power supply? Or can I insert Pomona banana jacks into the terminals?**
A: You will need a size of at least 6mm for the spade lug or a diameter of 4mm for banana jacks.
Hope you find this helpful.

**Q: could this power a 500w 4-channel amplifier for car speakers? it has a 60amp fuse and only requires 12v to turn on.**
A: short answer is no.  13.8 is standard automotive voltage at maximum charge, so that will be fine.  but this PS will not deliver the 60 amps.  most likely the self-protection circuit in the PS will "fold back", that is deliberately throttle the current delivered to a low value.  this normally entails a concurrent reduction in output voltage and that will cause your amp to turn-off.  turning the PS power switch momentarily off should clear the fault.  while both amp and PS may survive the event, it is a warning that either could fail the next time around.

**Q: Can this supply be used to power a 5 amp dc motor?**
A: I'm afraid that the SPS-1330 is not designed for powering DC motors.
We recommend you choose an adjustable DC power supply instead, such as our SPS-3005 series.

**Q: Is this a switching supply ??????**
A: Yes, this is a switching power supply.

### ⭐⭐⭐⭐⭐ Nice power supply
*by A***E on July 20, 2024*

I like this little supply, and it is little, small and light. This is my first switching supply. I always liked the ones with the big, heavy power transformers.

### ⭐⭐⭐⭐⭐ Nice unit, quiet RF
*by S***H on October 20, 2025*

So far it’s working great I power a couple of radios and a small hf amplifier. I have only drawn up to about 40 A but the unit itself is very nice. Very quiet rf wise and physically.
