    Very good DC-DC converter I found model number and circuit as h11068A The speciifications is below. DC-DC Boost Converter 8~32V to 45~390V High Voltage Charging Booster Module 40W Input Voltage: 8~32V input (the default is 10~32V input.) Input Current: 5A (Max) Output Voltage: +45~390V continuously adjustable Operating frequency: 75 KHz Output Current: 0.2A Max (the higher the output voltage, output current is smaller) Output Power: 40W (Peak 70W) Working Temperature: -40 ~ + 85 degrees Conversion efficiency: up to 88% Short circuit protection: Yes. Over current protection: Yes.((Input current exceeds 4.5A) Over voltage protection: Yes. (Output voltage exceeds 410V) Input reverse polarity protection: Yes Size(L*W*H):60 x 50 x 20 mm

    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.

    Sembra un piccolo modulo grande, peccato che fosse imballato male, non involucro protettivo per la spedizione!È stato spedito in una borsa antistatica in una borsa di spedizione sottile come in foto, per fortuna anche se un po 'piegato in un unico pezzo.

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

    Good power supply, perfect on my lab to supply during testing and repair old radios with vacuum tubes.

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

    Parfaits pour moi et petits montages réseaux panneau solaire sensibilité de l’ajustement ampérage est très sensible mais passable Mercis je planifie installer fane pour refroidir au qu'a ou .
