Universal board for a bipolar power supply for low and medium power amplifiers (up to 100 W).
Perfectly suits for such microcircuits as TDA2030A / TDA2050 / TDA7293 / TDA7294 / LM1875 / LM3875 / LM3886 and transistor amplifiers up to 100W
This power supply is designed to connect to two secondary windings of the transformer with a connection at the midpoint and a maximum alternating voltage AC25V-0-25V
The bridge diodes are shunted with film, and the PSU outputs are shunted with high-quality film, polypropylene capacitors. On the board there is an LED indication of the output voltage: red "+", blue "-"
It is not recommended to use the power supply at maximum voltage, since power surges in the power supply network can damage electrolytic capacitors.
Optimum AC Voltage
AC 22V-0-22V AC
It will not be superfluous to connect through a soft start system, as when the power supply is turned on, the capacitors are discharged and at the initial (short-term) moment the charging current of the capacitors is almost equal to the short-circuit current.
Includes 4 racks with bolts and nuts M2 for mounting in the housing.
Diode bridge 15A
Capacitance 24000uF (12000uF on the shoulder)
