SPS-50II

This thing rips! Works well for all my desktop power needs from my FT-991A to charging my Lipo4 batteries with Anderson. Voltage seems stable, doesn’t seem to be affected by being out in the field when I’ve needed it. And I really like the LED lit voltage and amperage gauges. Over all a decent quality unit with out breaking the bank.

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.

Well built, works as it should and the meters are both lit up and accurate. Well worth the money.

Have had for a while now.Have been running my FT857D, FT7800R, and a IC2300H with easy all at the same time.Very quiet fan, no heating problems.Would highly recommend to anyone looking for a new 50amp power supply.Only down side is, I've seen the voltage float slightly when using the variable voltage control, but no varying when switch is set to the 13.8 position.

Work well so far, good product don't know about durability yet, I will follow up on that.

I've been running this power supply to run my RM Italy Kl703 500w amp, works great, zero issues, no noise, no complaints here.

Initial review of the unit, its well and is made of metal, its well lit, easy to see the meters with a built in light when in use. Plenty of power at 30 amps and has room to power extra accessories. The unit also has the ability to be able to adjust the power output by flipping a switch on the back ranging from 9 volts to 15 volts dc. The unit is quite, lite so you can take it along if you want. Very nice, very accurate well made power supply.

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.
