This is the world's most compact 30A switching power supply that also has a meter and adjustable voltage control. Just 5" W x 2½" H x 6" D, it weighs only 3 lbs. -- it is the perfect pack-n-go power supply for field day, DXpeditions, camping, hiking or to pack for your next business trip or vacation to some far away place. MFJ-4230MV gives you 25 Amps continuously or 30 Amps surge at 13.8 VDC. The voltage is front-panel adjustable from 4 to 16 Volts. MFJ-4230MV also has a selectable input voltage: choose from 120 or 240 VAC at 47 - 63 Hz. A simple front-panel push-button switch lets you choose either Ampmeter or Voltmeter -- allows you to select Amps or Volts as you wish to read them. MFJ-4230MV has an excellent 75% efficiency and extra low ripple and noise, < 100 mV. A whisper-quiet fan cools by convection and forced air cooling. Normal air-flow around the power supply is continuous and a heat sensor increases the fan speed when the temperature rises above 70 degrees Celsius. DC output is binding posts on the back of the MFJ-4230MV so you can power your dedicated HF, VHF or UHF transceiver with ease. All MFJ switching power supplies are protected by MFJ's famous NoMatterWhat™ one year limited warranty. MFJ will repair or replace (at our option) your switching power supply, no matter what, for one complete year. Videos Product Manuals Download Product Manual
