SS-25M ASTRON SS25M [SS25M] $158.95 Click to enlarge 20Amp SWITCHING SUPPLY W/VOLT & AMMETERS This is a special order item. We do not normally stock it. We will order it for you. High Efficiency Switching Technology Specifically Filtered for Use with Communications Equipment, For ALL Frequencies Including HF . Heavy Duty Design The Astron SS-30M power supply. I picked up the new power supply last week on Friday from the post office just in time for the CQ WW CW DX contest. The power supply I ended up choosing was the Astron 30 amp switching power supply. Yes I wandered away from the linear power supplies and into the dark side of the switching power supplies. The SS-25M model supports currents up to 20A avg and peak up to 25A ICS (*) peak max. It is ideally suited for use with 12/13.8 VDC communications equipment. Switching technology >82% efficient meets individual power loading requirements. Included is special filter circuitry especially suited for all communications frequencies and HF. The LEDs I used are (Mouser P/N: 593-VAOL-3MWY4). A high intensity, small clear white, 3mm LED costing $.36 ea. LEDs have a focal point which is fairly sharp at close range. I bent each LED to shine across to opposite sides of the meter scale (X fashion) to broaden the beam of light on the rear of the meter scale. special features• three conductor power cord except for rs-3a • solid state electronically regulated • one year warranty • made in u.s.a. • fold-back current limiting protects power supply performance specifications from excessive current & continuous shorted output • input voltage: 105-125 vac • crowbar over voltage protection on all models … Alinco has just announced a New 144/440MHz Mobile.
