Hi,
I recently received a.m. EVM.
Trying to verify the efficiency data given in the manual on page 12 (table 4, no load, VIN = 230 V) I could NOT measure/confirm the given results. While table 4, line 1, states a "no load" Pin of 0.060 W. Measuring power at the input with a lost cost energy meter shows a value of approx. 0.8 W. and a current flow of 19 mA. Verifying this result with a more expensive/accurate DMM confirms a current flow of 18.9 mA with no load.
Any idea how to explain this difference?
By the way: all other data can be measured/verified with differences < 1%
On the pcb you find a note " not FCC approved ..."
What is missing on the EVM in order to meet FCC approval?
