Description:

High voltage Output:
DC150V /180V /200V /220V /240V /250V /280V / 300V for choose， pls tell us what output voltage you need when order it ！
Dual voltage output （0-DC150V 0-DC150V）

Max currnet ：3A

Low voltage： default 0-12.6VDC （can adjust between 5V to 15V ）

PCB size: 130x70mm

PSU board height：40mm

Parameters:

1. This board can also be applied to other tube 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.

3.The 5W voltage regulator tube package position is connected in series. When the output voltage is required to be 200V, one of the 200W voltage regulators can be installed, and the other position needs to be short-circuited.
