250W tube power amplifier tube amplifier switching power supply 300V0.6A 12.6V4A 6.3V4A delay open circuit-300V0.6A 12.6V 6.3V

In order to meet the needs of more customers, we are now launching customized services. The maximum voltage of customized models does not exceed 350V. Please communicate with customer service about your customized requirements. Thank you.

250W switching power supply for tube amplifier, compact size and strong power.

The filament voltage and the 300V voltage adopt independent ground wires, which are isolated from each other and do not interfere with each other.

300V uses a delay-on circuit. After power-on, the filament voltage is first preheated for 30 seconds. After a delay of 30 seconds, the 300V voltage is output, which effectively reduces the impact on the tube.

The output voltage:

300V0.6A, 12.6V4A, 6.3V4A

Note:

To prevent the filament voltage and the signal ground wire from interfering with each other, the 300V ground wire and the filament voltage ground wire are isolated from each other, and the ground wire needs to be connected separately!

8.25mm pitch high-current terminal, directly screw the screw ing, firm and safe.
