Universal bipolar power supply module for a powerful AF amplifier.
Perfect for transistor amplifiers up to medium and high power. The power supply is designed for connection to two secondary windings of a transformer with a mid-point connection and a maximum AC voltage of AC70V-0-70V
Bridge diodes 4 original ultra-fast diode assemblies for 20A "D92-02" for welding inverters in the TO247 case, the PSU outputs are shunted with high-quality film, polypropylene capacitors. The rectifier diodes are mounted on heatsinks, which improves reliability and allows the use of these power supplies with a constant load in relatively closed cases. The power supply uses NEW capacitors K50-18, 100V - 10000uF, removed from storage. Before assembling the module, these capacitors are molded at operating voltages and are completely ready for operation. The average capacitance of the K50-18 capacitors is 12000uF, hence the total capacitance of the PSU capacitors is increased by 4000uF as a bonus.
It is not recommended to use the power supply at a voltage higher than AC70V-0-70V, as voltage surges in the power supply network can damage the electrolytic capacitors.
Optimum alternating voltage AC 65V-0-65V
It is MANDATORY recommended to connect via a soft start system, because 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 brackets for attaching to the case.
