High Voltage 0-400V 22mA-600mA Regulated Power Supply TCA785

The power supply voltage setting from 0 ... 22ma 400v ... 600mA (maximum 1a) is able to cross the current setting on the circuit TCA785 phase control IC is not complicated, but the voltage is higher than we are used to design different systems used to feed at one dcdc converter tl081 opamp difficult market Sounds like to me is not necessary, but can be found in the author used the symmetrical supply opamp tl081 15v dc voltage operated with +-12v 2x12V çevirilip the integrated converter fed dcdc or additional transformer can be used instead of or in addition to TRA2 transformer windings can be selected accordingly. Of the power supply circuit, pcb, schema, there are drawings and bill of materials ..
