Universal board for a bipolar power supply for low and medium power amplifiers (up to 150 W).
Ideal for chips like TDA2030A / TDA2050 / TDA7293 / TDA7294 / LM1875 / LM3875 / LM3886 and transistor amplifiers up to 150W
This power supply unit is designed for connection to two secondary windings of a transformer with a mid-point connection and a maximum alternating voltage AC35V-0-35V
The bridge diodes are shunted with film, and the PSU outputs are shunted with high-quality film, polypropylene capacitors. The board has 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.
Optimal AC voltage AC 32V-0-32V
Connection through a soft start system is highly recommended, 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 40 940uF (20470uF on the shoulder)
