[Kenwood] Power Supply for TS2000

Tue, 26 Feb 2002 16:50:15 -0800

A word of caution about the RS (or RM) 35.

I too have one and it is very reliable. However, under
full load, the output transistors on the back and heat
sink get extremely hot. My temperature measurement
indicated over 70 Deg. C. This figure will depend on
the amount of convection air available. Although, 70 deg.
still allows some safety for the transistors, it is to close
for 'comfort'.
I installed  two, 3" fans with temperature sensor at about
50 - 55 Deg. C. When the one of the transistor reaches the
50 Deg. temperature, the fans turn on. There is slight hysterysis
for the turn OFF.

Good luck,

Mort, KB6BSN
