DC power supply for MFJ-259B MFJ-945E MFJ-949E MFJ-993B 127512VDC 1 amp MFJ-1312

Description: This listing is for a DC power supply to power *most MFJ devices (incl MFJ-259B MFJ-945E MFJ-949E MFJ-993B MFJ-1275 and MORE!)Similar to MFJ 1312D Whatever the MFJ-1312D can power, our product can power and is REGULATED 12vdc FOR LESS than the factory product! WHY PAY MORE? Specifications: AC input: 100-240 vac 50/60 Hz, 0.3a Output connector: 2.1mm x 5.5mm on 58" (~5 feet) cable, center positive DC output: 12.0 vdc up to 1 amp (will power any device needing 12.0 vdc and current UP TO 1000 ma at 12 vdc This power supply provides REGULATED and STABLE voltage output at any current draw up to 1 amp. What does this mean? Typical analog (transformer based and heavy) power supplies usually have a very high voltage output that is reduced only by the LOAD that is placed on them! That means that if you use a power supply with greater current capacity and draw less than that rated current, you will be presenting a much higher voltage to your device and potentially causing damage! Example: If your analog wall wart is rated at 500 ma but you only draw 200 ma, the voltage WILL BE HIGHER and potentially damage your powered device! So, whatever device that requires up to 1 amp (1000 ma) at 12.0 vdc will be handled properly by this power supply. *If your device needs (nominal) 12.0 VDC at (up to) 1 amp, 1000 ma and connects via a 2.1 x 5.5 mm standard coaxial connector, center positive I wonder how many of these other power supply sellers actually are HAMS? Or even have EVER tested their offering on any MFJ products? Sold by a real active HAM who has tested and uses this with his MFJ devices! 73, Dan W7RF ( Radiodan )
