yes, can be supplied from any voltage in range of +-12V to +-60V if the voltage regulator ballast resistors are properly chosed.

Then I would like to buy 3 of them, setup to support the voltage range from my previous post.

Ok, please leave a note when you order them about the required supply voltage.

Hello Cristi!
Display the schematics or project for SMPS +/-35V/2x5A.
thanks

Hi I bought a BIPS and waiting the delivery. Do you have the schematics and other documentation please ? Thx

I attached the BIPS schematic on the forum in few places, i will do it again here.
what need to consider is R5, R16 which set the overall gain, in this case 1. if other value is needed, can be chosen by the ratio of R5/R3 for left channel and R16/R22+1 for right channel. the op-amps are supplied through the 1W resistors and 12V zenner diodes. the resistors should be chosen to allow BIPS to be supplied with the available voltage, which can be in range of +-12V to +-60V. for +-12V, 33-56R resistors should be used, and for +-60V 2k2-2k7/1W resistors should be used.

Is BIPS attenuating the signal by 20dB before entering the opamps?
