LDMOS AMP (OR BENCH) POWER SUPPLY 45V!: Perfect for that LDMOS amp project or use as a bench supply. I have two left . (I also have 12 and 24 volt versions). My company bought another company and these were in their engineering closet. Brand new in box. 109-120 Volt input. I placed a 3 ohm resistor on one and at 15 Amps (675 watts) they didn't even flinch. My meter read 45.1 volts unloaded and 45.1 with the 3 ohm load. I don't have a resistor any smaller to load it more but this will give you an idea of their regulation. There is a screwdriver pot to set the voltage and another for current. I backed the voltage down to less than 1 Volt so if you replace them with regular pots they could make a very nice bench supply. I haven't tested the current adjustment so I don't know if they crowbar or drop the voltage to your set level. $90 firm each shipped in cont. USA. Brand new but sold as is due to the nature of electronics. Good check (shipped after clearing) or Postal MO okay. Save $10 if you pick up in CT. 73.
