Absolutely enjoy this power supply. It has easily become the 2nd. best investment I have made. I have had it for the last month and a half and I power my FT-7900 radio, MFJ-842 and soon a 900 Mhz radio. Thanks for the unboxing!

Hi Pascal, This might sound lake a crazy request but could you possibly tell me if this power supply has continuity between the DC -ve connector and the mains earth pin? The reason is that in the UK our IEE (mains supply electrical) regulations prevent the RF grounding system (copper ground rod) from being connected to the utility company ground. So with this in mind, having a dc -ve connection which has continuity to mains earth/ground provides that connection via the radio chassis (as most radios have their chassis connected to -ve supply). Therefore the answer is to have a power supply with floating ground on the DC side. I'm trying to find one which definitely has this (as I am told some do) before I click the buy button. A simple test to connect ohm meter between mains ground pin and the DC output -ve connection to see if it is shorted or open would suffice if you are willing? Many thanks and loving your content. Best wishes, Paul, Scotland.

Does the fan on the PS run all the time? I have an MFJ 4225MV. The fan runs all the time and after awhile the noise is a nuisance. Thank you

Hi, mine fan only start when I turn it on, but my shack is never above 22 Celcius. Also I transmited with my QRP transceiver and the fan never started. So I guess I will have to try at 100W to confirm. 73 Pascal VA2PV

Bien hâte de voir le résultat avec la filtration en HF et la fiabilité long terme. Parce qu'avec le MFJ-4115, un autre switching power supply, plusieurs amateurs avaient des problèmes de RFI et de bruit. Pourtant, les specs et la grosseur vs la capacité (15A), semblaient idéal pour le portable (format réduit). Le SS-30DV ou Samlex 1235M ne semblaient pas un bon choix pour toi pour le portable ou est-ce le prix qui ta vraiment attiré?

Bonjour Hugo, j'utilise le bloc d'alimentation depuis plus d'une semaine sans problème et sans aucune interférence. Rien a dire, très heureux. Le prix est un facteur déterminant, mais j'aime le look et le format de celui-ci. De plus, je ne peux pas répondre pour les autres mais je sais que les produits MFJ sont destinés au marché radioamateur, donc conçu pour fonctionner sur nos bandes. Les "switching" sont désormais supérieur en efficacité que les blocs d'alimentations traditionnel en plus d'être plus efficace (énergie). Considérant le format c'est excellent. 73 Pascal VA2PV

le ventilateur est-il bruyant ? assez puissant pour rouler un hf 100 watts ou c'est trop limite ?

Bonjour, je suis très satisfait de ce bloc d'alimentation. Finalement je l'utilise en permanence et j'ai vendu deux autres blocs d'alimentation, car celui-ci les remplace. Les autres étaient, un Astron 20M (20 amp.) et un Astron 35M (35 amp.). Ceux-ci avaient des transfos vibreurs, depuis avec le MFJ-4230MVP je n'entends plus rien !!! J'entends le ventilateur uniquement à l'allumage, mais très brièvement. Par contre, j'utilise que 2 à 5 ampères normalement et à l'occasion 10 à 12. Techniquement je ne vois aucun enjeu pour l'utiliser avec un radio 100W. 73 Pascal VA2PV

Hello, Pascal. Is it noisy?
@Laboenligne

No not at all, sometime the fan goes on but it’s less noisy than the trnasformer vibration noise of my former Astron tradionnal 30 amp power supply. 73 Pascal VA2PV

what's the wattage on the mfj
@Laboenligne
@Laboenligne 7 жыл бұрын
It's 30 amps at 13.8 Volts = 414 Watts (that's peak), it's 25 amps continuous = 345 Watts
