Voltage drop on SSR01 under load
« on: March 17, 2019, 02:18:54 PM »
Per Anders,

I have installed a +12V SSR01 regulator to power up a DDDAC board. At no load, the regulator provides 12.3V but when the DAC board is connected, the output voltage from the regulator drops to 2.5V.

I was wondering if other users have already faced this issue, and how to solve it. Thanks for any input you could provide!

Operation conditions are as follows:
On the SSR01 board, both J1 and J2 are bridged.
The DAC board should be drawing around 100mA.
Input voltage is 30VDC
There is a large heatsink over the LM317
Upfront DC regulation is done with a LC circuit (diode bridge, 17H in series, 100uF polypro in parallel)
