    • Good Budget power supply for Amateur Radio!
Size: 30II(9-15V 30A)
Good power supply. I ran 3 radios on it, a DB-40G GMRS, Yaesu FT3185Rasp, and a Yaesu FT-710. Works well, the FT710 at 100 watts is all it wants with the other 2 radios sitting idle. Very stable voltage, and not much switching noise... which you can move around with the knob on the front panel if needed. Meters are very sensitive and accurate... and the voltage control is very stable, less than .1 volt deviation when transmitting SSB at 100 watts. I replaced it with an Astron RS-35M since I'm partial to Linear power supplies, but I'll keep this one as a spare. Definitely would buy another. ... show more

    • Great Power Supply for the Price
Size: 30II(9-15V 30A)
Wonderful Power Supply, does exactly what it says. All of the things work on it, the lights, the meters. The back has a 13.8V switch for HAM Radio purposes as well. Super easy to set up and use, and is extremely accurate on the product. Great value for the money, and makes close to no noise. Sits well on the table and is about the same dimensions as a radio, so fits well on the table for it's size. ... show more

    • Good solid power supply
Size: 30II(9-15V 30A)
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. ... show more

    • Decent power supply for a great price
Size: 30II(9-15V 30A)
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. ... show more
