Smart Electronics TDA7293/TDA7294 Mono Channel Amplifier Module Circuit PCB Bare Board 4XFB

TDA7293/TDA7294 Mono Channel Amplifier Module Circuit PCB Bare Board 4XFB

Model: TDA7293/TDA7294
Power supply: double AC 15V to 36V (AC needs rectification and filtering) or DC positive and negative
18V to 50V.Recommended double 35V (Note that it is not a dual 35V transformer, it is positive and
negative 35V DC. And It is recommended to double 26V/200W toroidal transformer, after rectification
voltage is about DC double 35V).

Model: TDA7293/TDA7294
Power supply: double AC 15V to 36V (AC needs rectification and filtering) or DC positive and negative
18V to 50V.Recommended double 35V (Note that it is not a dual 35V transformer, it is positive and
negative 35V DC. And It is recommended to double 26V/200W toroidal transformer, after rectification
voltage is about DC double 35V).

Reminder: The battery can be used! (Must be a battery in series).
Transformer power: The power of the power supply transformer should not be less than 200w
when the two channels are used. The power of the power supply transformer should not be less
than 100W when mono.

The power supply rectifier filter: the total of the two channels should not be less than 40,000 uF,
the rectifier bridge is preferably 25A or more.
Output power: maximum output power 85W
Midpoint voltage: less than 1mV
Load: It can promote large-scale floor-standing speakers for home use.
Radiator: According to the supply voltage, the power supply has a high heat output and a large output power.
Plate material: FR4 double-sided fiberglass board, 2 amps of copper, blue ink, double-sided spray tin.
