ePure swissvoice red DE phone
« on: October 04, 2022, 08:08:26 am »
Hi everyone,

I recentely purchased an ePure swissvoice red DE telephone without the power adapter. Opening the phone I can see that the adapter supplies two voltages. Does anybody know what they are?

Thanks for your time.

Power Adapter Output:
1-2 =  6.5V DC 300 mA
5-6 =  7.5V DC 200 mA

Those numbers seem weird.  Only 1V difference?

PeDre Are you able to check if the two supplies are fully isolated or if they share a reference rail?

I measure 7.7 V and 7 V in the unloaded state, and cannot measure a common ground, so the voltages are isolated. There is also a charging station that looks the same, it only needs a voltage of 7.5 V.
