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: Best 50 Amp Power Supply for the Money - I have had this power supply now for several months and it works as advertised. I like that it has two LED lit dials, one for amps being drawn and one for voltage. I have mine set for 13.8 volts DC as recommended by most amateur radio gear. When transmitting with my HF or VHF transceiver at 100 watts, the voltage does not drop any nor does the needle even flicker. The amp meter does show the proper amount of amperage being used. The fan does NOT run constantly like a lot of the switching power supplies do. It is a very quiet power supply. The fan will come on if I am running high wattage on 100% duty cycle modes of transmission. The fan runs only until the unit cools back down and the fan is not very loud. The unit has a voltage adjust knob on the front along with an offset knob for moving any "birdies" that the power supply might generate, but I have not found that to be a problem. There are also two sets of Anderson Power Poles on the front along with a cigarette lighter type outlet. The main power is supplied through two heavy duty connectors on the back of the unit. I do highly recommend this power supply for a radio amateur and the price is the best around for a 50 amp supply.

## Features

- 【Voltage Control】The output voltage is continuously adjustable from 9V to 15V or set at a fixed 13.8V. The Noise Offset Circuit moves unwanted switching noise to another frequency.
- 【Screw-type main terminals】The main output terminals ensure easy compatibility with all DC-powered devices and are large enough to provide an efficient power transfer to your equipment.
- 【Auxiliary Output Terminals】2 pairs of auxiliary snap-in terminals and a cigarette lighter socket on the front panel for added convenience.
- 【Analog V/A Meters】Highly visible V/A twin meters for real-time monitoring of the status.
- 【Forced Air Cooling Fan & Protection】A built-in cooling fan that prevents overheating and keeps the unit running continuously under heavy loads. Advanced short circuit protection and automatic current limiting ensure the safety of operators and any connected electrical equipment.

## 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.

### ⭐⭐⭐⭐⭐ The 50 amp and 60 are great power supply’s
*by J***O on July 23, 2025*

Received in new perfect condition. Works as advertised. Everything checked out. Using it now for my ham radio station. 40 amps continuous and 50 amps surge. Good size power supply and fits nicely on shelf. Very happy with my purchase. Would recommend this supply. Once again time will tell when I get some hours behind it. But for now it’s working great. I like how the meters have light on them. Light brightness is perfect not like looking into a flashlight. Also the layout of controls and connectors are very well planned out. Update, my 50 amp power supply is still working great! Plus I just received my 60 amp with LCD display. I needed more current for my two amplifiers I purchased. UHF 160 watts and VHF 350 watts. My antenna can only handle 330 watts. So I keep the High power setting at 300 watts. The 60 amp power supply works great. Just needed to update this because there were now reviews about this model. Only had this one day. But if it’s like my 50 amp, I expect it will hold up just fine. Beautiful power supply’s. Highly recommend!!!!!
