Review Summary For : RS MFJ-412SP 25A Switching PS w/PowerPoles
Reviews: 2MSRP: 124.95
Really GREAT Little Power Supply!

NOTE: MFJ-4125P is similar to MFJ-4125. Adds 2-pair of Anderson PowerPoleTM connections.

The MFJ-4125 Switching Power Supply is similar to the popular MFJ-4225MV but much smaller and doesnt have meters or the cigarette lighter socket.

5-way binding posts are for high current radio connects and a pair of speaker type push-on terminals are for low current accessories. Super protection modes include Over Voltage and Over Current. Whisper quiet internal cooling fan generates tremendous air flow to help keep components cool.

The MFJ-4125 Switching Power Supply has switchable AC input voltage. 110 VAC at 47-62 Hz and 220 VAC at 47-63 Hz. Super regulation. Works with AC input 85-135 VAC or 170-260 VAC.

It weighs only 2.9 pounds and measures an unbelievable 5½W x 2½H x 5¾D -- its the smallest and lightest power supply in ham radio!

Just a trooper! Time Owned: more than 12 months.
I bought this PS via HRO in Atlanta for a 2M/70cm rig. The Powerpole outlets were very attractive as was the price. I've since used it for my Yaesu FT-857D and an FT-1500M as needed. It's really fairly quiet in my opinion. It has been a "perfect" performer with not a single think I could complain about. I'd buy another in a minute if needed.

GREAT PRODUCT! Time Owned: 0 to 3 months.
Excellent little 25A Switching PS w/two pairs of PowerPoles on the front panel! In additions, it has binding posts for 25A on the front panel and a speaker type quick disconnect at 5A for accessories on the back panel.
