Linear power supply

[allsorts]

If it really does have 80 mV of 50 kHz (+/-) on the output it might be too noisy for a blue controller. The TL-POE10R I use to power mine had about 100 mV P-P noise and the controller wasn't happy. The simple two toroids and capacitors filter cured that though reducing the noise to 5 mV P-P (if the V_in monitor on the signals page of a controller is to be believed).
