What is the spade lug size needed for this power supply? Or can I insert Pomona banana jacks into the terminals?

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.

could this power a 500w 4-channel amplifier for car speakers? it has a 60amp fuse and only requires 12v to turn on.

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.

Can this supply be used to power a 5 amp dc motor?

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.

Is this a switching supply ??????

Yes, this is a switching power supply.

Einfach und gut

Dieses preiswerte Netzteil betreibt meine Amateurfunkstation (2m und 70cm). Alles ist sehr robust gebaut, das Voll-Metallgehäuse schirmt gut ab. Es gibt keine Spannungseinbrüche beim Senden, d.h. die Spannungsstabilisierung funktioniert auch.

ottima scelta

decisamente il prezzo più basso sul mercato. Stabile poco rumoroso e con l'aggiunta di uno strumento di misura diventa una macchina ideale

MY POWER INVERTER

I DECIDED TO PURCHASE THIS INVERTER FOR TWO REASONS ONE IF IT EVER GETS HOT ENOUGH IT HAS A FAN THAT WILL COME ON AUTOMATICALLY AND TWO FOR IT BEING 30 AMPS. I GOT IT TO POWER MY CB RADIOS AT 13.8 DC VOLTS AND IT DOES ABOUT 14.1VOLTS WHICH IS GREAT FOR WHAT I WANT IT TO POWER. I HAVE A 40 CHANNEL CB AND 100 WATT KICKER AND THE FAN HAS NEVER COME ON SINCE I PLUGGED IT IN TO USE IT. IT IS WHISPER QUIET AND NO INTERFERENCE COMING IN THE RADIO FROM IT. ALSO THE UNIT ITSELF HAS NEVER GOT WARM TO THE TOUCH EITHER, LIKE FROM OVER DRIVING IT. SO IF YOUR WANTING TO SET UP A CB BASE STATION IN THE HOUSE, DON'T OVER LOOK THIS INVERTER WHICH IS SMALL AND OF GOOD QUALITY GOOD VALUE AND PERFORMANCE AND WHISPER QUIET. IT DOES HAVE A FUSE AND THAT WILL LET YOU KNOW WHEN SOMETHING ISN'T RIGHT JUST IN CASE. OK THEN I'M DONE. 73'S--027TAMPABAY..

Nice and compact.

Does the job. Bought it to connect an ICOM 7300 100w to it and a VHF/UHF 50/25w and it performs well. It's nice and compact compared with other bulky power supplies

Nickel, conforme au descriptif et semble de bonne qualité.

Impeccable pour alimenter une CB en poste fixe . De la réserve de puissance pour un ou deux postes plus pechus.
