Tom,
Below are the power requirements for both the Kenwood TS-570 and the Kenwood
TS-590.
Also below you will find the specifications for the Kenwood PS-53 power
supply.
This information came directly from the print manuals that I own.
As you will see, the TS-590 uses slightly less power on receive than does
the TS-570. Transmit for both are the same.
I have been using my TS-590 on my PS-53 with no issues.
Since the specifications, power wise, is basically the same for both
transceivers, you should have no issues.
Power Requirements: TS-570
Voltage 13.8 VDC Plus or Minus 15%
Current Requirements:
Transmit 100 Watts - 20.5 Amps
Receive with no signal - 2.0 Amps
Power Requirements: Kenwood TS-590
Voltage 13.8 VDC Plus or Minus 15%
Current Requirements:
Transmit Max. - Less than 20.5 Amps
Receive with no signal - Less than 1.5 Amps
PS-53
Rated Output Current:
22.5 Amps (25% duty cycle)
16 Amps (50% duty cycle)
20.5 Amps max (continuous operation for 1 hour)

>> Hello, everyone.
>>
>>
>>
>> I think I'm becoming more and more convinced that something might be
>> going wrong with the trusty Astron RS35 linear power supply that I
>> have been using here in the home shack for the past 18 years.
>>
>>
>>
>> Today, I had my XYL check the meters on the supply when keying up in
>> RTTY mode with 100 watts with my TS590, and the meters on the supply
>> read 14 volts, with only a draw of 11 amps. I did this on a frequency
>> for which my DXCC antenna is resonant on 40 meters. My SWR was 1.0 to
>> 1, both according to the TW1 and the meter on the TS590. I then
>> checked my output power reading. According to the TW1, it was 57
>> watts, and according to the
>> TS590
>> meter, the output power was 75 watts.
>>
>>
>>
>> After our lenghthy discussions several weeks ago, when I noticed
>> output power problems with my TMV71A, I tried my best to clean all DC
>> power connections.
>>
>>
>>
>>
>>
>> My next step will be to try another power supply, just to see if that
>> makes a difference, which brings up a question.
>>
>>
>>
>> Does anyone on list have a Kenwood PS53 power supply? I obtained this
>> supply from an estate sale several years ago, and I think it is meant
>> to be used with the Kenwood TS570, which I also obtained at that time.
>>
>>
>>
>> I had my XYL check the power draw ratings on the supply, and she told
>> me it says 16 amps. This seems a bit low to me, and may not be
>> adequate for the
>> TS590 on the full 100 watts.
>>
>>
>>
>> If anyone has accurate power draw ratings, or an accessible manual for
>> the
>> PS53 supply, I'd appreciate the additional info.
>>
>>
>>
>> I'm hoping to do some further experimenting with all of this during
>> the upcoming Thanksgiving break.
