Hi there
I have a brand new SDR-1000 her at home for evaluation.

I have found that the unit pulls 840mA from the 13.8 supply during stand by (big switch off).
When Switch on the unit pulls 930mA.

I´m sure there must be something wrong with the unit. This as I can not get any power out
of the 100W PA. I have not yet tried the exiter-part to veryfy if there something wrong
with this to start with.

Anyway. Any other of you having the experience of a very high current drawn in standby ?

(the PA heatsink gets warm during stand by of course )

Tilman,

The current draw when the power switch is turned off is normal if you have the 100 Watt PA.

If so, then I´ma afraid to say that we are dealing with bad design.

I do not see the point in having to switch off the powersupply (I´m using it four other devices) not to be waisting 0.84mA x 13.8 V = 11.6 Watts even when the unit is "switched off".

I have suggested to Gerald Y to incorporate this fix with implementing a temp-controlled FAN.
