The MFJ PC-205 is a switching DC power supply designed for electronic equipment that requires a stable and adjustable power source.

Its output voltage can be adjusted from 0 to 15 V DC, while the current limit can be set between 0 and 20 A. The constant-voltage (CV) and constant-current (CC) operating modes help prevent the output from exceeding the values selected by the user.

The white 4-digit digital display provides voltage, current and power readings. A resolution of 0.01 V and 0.01 A enables accurate adjustments during testing, repair and laboratory work.

Its compact design makes it suitable for amateur radio stations, compatible CB and VHF/UHF equipment, electronics workshops, laboratories, fault diagnosis and prototype development.

Important note

Before connecting the equipment, set the correct voltage and current limit for the intended load. Always check the polarity and maximum current consumption, and use cables with a suitable cross-section for currents of up to 20 A.

Keep all ventilation openings unobstructed. This power supply is intended exclusively for indoor use and must not be exposed to moisture, liquids, or flammable and corrosive environments.

The stated 20 A is the published maximum capacity. Check the actual current requirement of your transceiver, particularly during transmission, and allow a suitable safety margin.
