Samlex SEC-1235M Power Supply: Reduced price from $125 to $100 shipped. The Samlex SEC-1235M is a 30 amp continuous, 35 amp peak switching power supply. It comes from my non-smoking shack with the power cord. It has the AD5X fan modification installed. The modification keeps the fan running at a low speed, very quiet, yet still permits the fan to go to full speed if the temperature exceeds 60 degrees Celsius. With the fan running continuously at low speed, the SEC-1235M stays cool enough that it only goes to full speed under heavy, high current use. The modification was simple only requiring connecting a 100 ohm 1-watt resistor between the black fan lead and the negative DC output port. Sold AS IS.$100 shipped USA only. Payment via USPS money order or personal check.; Listing #1763698 - Submitted on 03/31/26 by Callsign WB7RBN, Modified on 04/15/26 - IP: 38.77.172.81; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
