WAWEIS 12V AC/DC adapter for MFJ 229 249 259 269 929 959 993

SKU CH-SDYQ-R5YCF

12 V AC/DC adapter with 100-240 V input, 6.5 ft cord and safety protections for MFJ 229, 249, 259, 269, 929, 959 and 993 analysers

  • World-wide 100-240 V input lets you power the analyser anywhere
  • 12 V DC output matches MFJ 229 249 259 269 929 959 993 exactly
  • 5 ft cord gives flexible bench placement
  • Over-current over-voltage and short-circuit protection guards the tuner
  • FCC CE RoHS certified for safety compliance

Replacement adapter for MFJ analysers

This 12 V AC/DC adapter replaces the original supply for MFJ-229, MFJ-249, MFJ-259, MFJ-259B, MFJ-269, MFJ-269C, MFJ-269Pro, MFJ-929, MFJ-959 and MFJ-993B antenna analysers and IntelliTuner automatic tuners. It delivers the 12 VDC rail those instruments expect. It is not for devices that require a different voltage or connector type.

Plug-in installation with 6.5 ft cord

The unit accepts 100-240 VAC at 50/60 Hz worldwide, so no voltage selector is needed. A 6.5 ft power cord reaches most bench outlets without an extension lead. Built-in over-current, over-voltage, short-circuit and total-power protection guard the analyser if a fault occurs. The brick runs warm under continuous transmit cycles; keep ventilation slots clear.

12 VDC output for listed models

The adapter supplies the rated 12 VDC current the specified MFJ analysers and tuners draw during receive and tune operations. Headroom covers normal SWR sweeps and automatic tuning sequences. Extended high-power transmit sessions or additional accessories connected to the same rail may exceed the brick’s capacity and trigger protection shutdown.
