The adustable high voltage power supply proviedes single or dual rail (depending on the type you order) power. It can widely used for many applications like huge nixie clocks, decatron spinners or any other tube circuites ... Ony when using it for analog or even audio applications a little bit more filtering of the output voltage is required since especially at higher power you have quite some switching noise. But for 99% of the applications it works perfect. Nevertheless the output power seems a little bit optimistic. I ran the module at apx. 30W input power (didn't measure the output current) and it got quite hot. But still very good output power for the value.

Ressemble à un grand petit module, dommage qu'il était mal emballé, pas d'emballage de protection pour l'expédition! A été expédié dans un sac antistatique dans un sac d'expédition mince comme dans pic, heureusement bien qu'un peu plié son en une seule pièce.

Looks like a great little module, pity it was badly packed, not protective wrapping for shipping! Was shipped in an antistatic bag in thin shipping bag as in pic, thankfully although a little bent up its in one piece.

Все отлично. Полноценный двухполярный преобразователь. То есть на выходе можно получить до 780В.

Брал для филаментных ламп. Работает нормально. Только вместо однополярного выхода прислали двухполярный, за что магазину большое спасибо.
