WAWEIS 12V AC/DC Adapter for MFJ 1312D 267 1312DX 6.5 Ft Cord

SKU CH-2JRH-67K9N

A 12 V AC/DC adapter with 6.5 ft cord and 500 mA output for MFJ antenna analysers and counters

  • World-wide 100-240 VAC input works across regions
  • 12 V to 13.8 V output at 500 mA powers compatible MFJ devices
  • 5 ft cord length gives flexible placement options
  • Over-current, over-voltage and short-circuit protection safeguards equipment
  • FCC, CE and RoHS certifications confirm safety compliance

Compatible power supply for MFJ antenna analysers

This 12 V AC/DC adapter replaces the original supply for MFJ-1312D, MFJ-267 and MFJ-1312DX analysers. It accepts a worldwide input of 100-240 VAC at 50 or 60 Hz and delivers 12.0-13.8 VDC at 500 mA. The 6.5 ft cord gives flexible placement on the bench or in the field.

Steady output with built-in safeguards

Over-current, over-voltage, short-circuit and total-power protection circuits engage automatically during extended use. The smart-chip design adds overheating and anti-interference isolation so the analyser receives clean, stable power throughout long measurement sessions. FCC, CE and RoHS certifications confirm compliance with international safety standards.

Direct replacement for the factory adapter

It upgrades worn or lost original supplies without modifying the analyser. The jump is worthwhile when the existing unit shows voltage drift, damaged connectors or missing safety approvals. Users needing a different voltage range or higher current rating should look elsewhere.

Questions about this item

How much heat or noise does the 12 V 500 mA adapter produce when it runs continuously?

The unit draws only 500 mA at 12 V and has no fan, so it stays cool and silent during all-day operation.

Which connector or cable must I already have on my MFJ device for this 6.5 ft cord to plug in?

The adapter terminates in the standard coaxial barrel plug used by the MFJ-1312D, MFJ-267 and MFJ-1312DX, so no extra cable is required.

Will the 100-240 VAC input work safely with the older 13.8 VDC MFJ antenna analyser I still use?

Yes, the wide-range input accepts 100-240 VAC 50/60 Hz and delivers a regulated 12.0-13.8 VDC output that matches the legacy analyser.
