However I hate big noisy fans, silence is golden! If i'm trying to hear a weak HF signal. Will power any 100W HF set with no problems and looks like it will last. I'm tempted to try and mod the PSU with a slower/less noisy fan.Īll in all a Very good PSU at a good price. I acturally need to turn the Volume up on the radio to compensate for it. Did I mention NOISE!? When the fan kicks on (which it seems to do often even with a low current draw it's LOUD! Far too LOUD. +Good value for money (about half the price of an equivalent 'branded' Yaesu or Icom PSU) +Protection for short circuit and overcurrent +The voltage is variable (though this is of no use to me, I just need 13.8 solid for all the gear) +Meters accuratly report the Voltage and Current Obviously, like any modification, you do it at your own risk - probably invalidates all guarantees and don't blame me if you blow the PSU, your rig, or both!!! The regulator is a two pin device screwed into the heatsink right behind the volt meter - it's a normally closed switch which opens when it gets hot - just unsolder either wire and drop in a series resistance to taste - 1.5k seems right to me. The modification is to drop a resistor of around 1.5k in series with the thermostat - that makes the fan idle at a moderate speed (and quietly) all the time, just kicking up to full speed if the temperature gets high. The trouble is that the thermostatic control of the fan is an all-or-nothing affair - it's off till the regulator is really quite hot, then it runs full blast till it's nearly cold. Unfortunately it's in German and doesn't translate well through bablefish, but I managed to work it out. I did a quick web search and found an article on mods.dk which describes how to kill the noise. I have the Manson branded version (EP-925) and, as others have reported, it's a good value PSU apart from the very high fan noise!
