Hi Steve
I have recently bought a 240VAC/12volt 5amp switchmode regulated power supply from Jaycars. It is Cat GH-1379 and cost about $30. Before I used it I did some bench tests with the following results:
No Load voltage: 12.93v.
Two amp load test for 1/2hour, voltage 12.78v (the unit was slightly warm
after this test as could be expected).
I measured the noise voltage on the 12volt output with an oscilloscope for both tests and it was negligible (less than 0.05volts).
I have since been using this power supply with my HEQ5PRO and ancillary gear with no problems.
Caution: The power supply is open vented and not for outdoor use (eg
where it is exposed to rain or heavy dew.) I have mine mounted on my
outdoor astro gear trolley on a covered shelf. If you cover a power supply make sure it is well ventilated.
Cheers Peter
