MFJ 1117

Thank you for purchasing the MFJ-1117 High Current DC Outle ts. The MFJ-1117 is very versatile in allowing y ou t o co nn ect to a s many a s four ( 4) di ffe rent HF or VH F rad ios at t he same time. The MFJ-1117 alleviates the problems of multiple radio connections to the same

terminals. Posts A and

one 35 amp fuse to handle a combined total of 35 amps. Note: While you may connect up to four (4) radios to the MFJ-1117, you may not draw mor e than

35 amps at one time.

The MFJ-1117 is not a power supply. The output voltage and current of the MFJ-1117 depend on the output voltage and curre nt o f the ma in DC pow er su p ply th at th e M FJ-11 1 7 is con nected t o.
