Description:

Power board input voltage 0-AC220V 0-AC220V 0-AC12.6V (High voltage 200V-265V Low voltage 12V-15V) Output voltage: 0-260VDC 0-260VDC 0-12.6VDC three sets of voltage PCB size: 130*70mm

Parameters:

1. This board can also be applied to other bile preamps. The high voltage output high voltage can be changed by replacing the Zener diode. The low voltage output board can be adjusted directly. 2. The high voltage output current of this power board is recommended to be less than 1A. Low pressure is recommended within 1.5A. The low pressure is up to 2A. More than 1.5A. LT1085/LM317 Pay attention to heat dissipation.

Note：

Bare pcb：just 1pcs pcb，have not any parts Diy kit：all parts need buyer to solder， Assembled board：have tested well，
