Power supply unit of a powerful amplifier with bipolar voltage from a 12V car network.
This converter is used to power powerful amplifiers with bipolar supply voltage. It can work with transistor amplifiers such as Lanzar, Slap hands to Mikruham, etc. and any microchip amplifiers like LM3886 / TDA7293 (4), etc.
The powerful toroidal transformer has separate windings for low-current circuits, connected through stabilizers of the 781x / 791x type. This solution provides FULL galvanic isolation for power amplifier and pre-amplifier / tone block / filter power supply, which reduces the possibility of interference and background by an order of magnitude.
The board has an LED indication of all voltages, including the input 12V. The control (inclusion) of the converter is carried out via the ACC line from the radio or ignition, through the relay on the board. If forced ventilation (cooling) is required, the board is designed to connect a standard fan to the KF2510 connector, while it is possible to adjust the fan speed, depending on the temperature. Connect the power to the module with a cable with a cross section of at least 6 mm. sq.
