PCB size is about 156*96mm
the assembeld board max height is about 32mm
output can be adjust at ±1.3V-35V.
Application A: ±15V for analog circuit, +5V for digital circuit a, +5V for digital circuit b.
Application B: ±15V for analog circuit, +5V for digital circuit a, -5V for digital circuit b.
Application C: ±15V for analog circuit, ± 24V for control circuit, ± 12-48V for phantom circuit.
Because of the flexible change of the ± output power of this board, it can adapt to most of the motorcycles such as CD players, DVD players, DAC players or microphone amplifiers.
Considering the voltage regulation performance and power consumption, it is recommended that the input AC be slightly larger than the required output DC.
For example, if you need +/-DC9V out, you can use dual AC10-12V
The long-term test conditions for our radiators are:
①Input AC12V, output DC12V, current 450mA.
②Input AC18V, output DC15V, current 200mA (if AC15V input is used, the load current can be larger)
The above two can be used as a reference. If you need a larger current, please add and modify the radiator by yourself.
